Rhodig lib. 4. cap. 16. Historia Rhodig says that some thought the heart to grow â„¥ ij in a year till man comes to 50. then so to decrease to an 100. which is the last period of life His parts are either externall or internall Externall as the Pericardium of which we have spoken his proper coat which is so thin that it cannot be separated His Adeps his two sorts of vessels the one which compasses the heart the other that enters the ventricle his Auriculae The internae are his fleshy substance his ventricles and vales Adeps is more in man then in any other creature Adeps which may make some wonderment if you consider his heat which will suffer little on the left ventricle but all on the right to the very Conon Massa will have it from the thicker part of the bloud the thinner evaporated But Achillinus hath invented a pretty one As butter is made by a strong motion so adeps here It is about the Basis where the greater and lesser vessels are seated Nature would have it Adeps non Pinguedo lest molten by

heated by his continuall motion it should dry but especially in great fastings and exercises and according to the increase or decrease of the heat doth it augment or diminish so much doth heat feed upon it Bauhinus observed many times certain pieces of fat to be in the ventricles Cordis But the Conus is moistned from the humour contained in Pericardio Coronaria valvula His vessell to nourish the

through and be broken with continuall motion It is more solid in the point then in the Basis and here the right fibres are more compacted and thicker then in the head of the muscles or tendons Sedas facultatis vitalis Omnia genera fibrarum This flesh is the seat of vitall faculty and the first cause of functions of the heart It hath all sorts of fibres though not conspicuous as in a muscle to make his motion and defence from injuries Therefore Galen calls it 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 or carnosum viscus It is not a muscle because it hath all sorts of fibres besides it hath naturall motion not voluntary as muscles have Motus is continuall Motus continuus to prevent his own combustion This is two-fold Diastole Systole which are made by his fibres and between the motion there is Quies duplex Quies duplex Diastole cum Conus ad Basin id est Perisystole Diastole or Amplification is when the point by his right fibres is drawn to the Basis of the heart and so the heart is

Arteriam venosâ—n This motion is called Systole seu contractio depressio dicitur This contraction is made by those strong ligaments which are in the inward ventricles of the heart which in contraction fall and bring with them the coats of the heart But the Motus Cordis originally is seated in the left ventricle Motus originaliter in sinistro Therefore the right needs no ventilation except communicated from the left as appears by those vessels of the left ventricle to which only pulsificall power is communicated So the motion of the right is like that in the ears which is because the neighbouring part moves or from agitation of the bloud not for that there is in it any faculty of moving for when the auricula are dilated the rest of the arteries are shut Quatuor motus duo auricularum duo ventricule rum So therefore in viva sectione Animalis alicujus four motions are observed differing in time and place 2. proper of the eares 2. of the ventricles Neither is this motion from the nerves as Fallopius and Piccolhominy would have it but from the Parechyma of the heart and so is naturall not animal and voluntary It hath 2. cavities which are called ventres Dextra Ventricu

Largior sinistro It 's larger and greater then the
other for the great quantity of bloud it receives Sinus sanguineus Ruf. Therefore of Rufus it 's called sinus sanguineus venosus It is a looser and softer flesh and of a thinner wall into this Vena Cava ascends whilest the heart is dilated it pours in his bloud that it might be here concocted and cleansed And of the thicker part the inward substance of the heart is nourished The thinner part with the same contraction per septum is sweat through into the left ventticle for the generation of vitall spirits Natus ad pulmones for for the lungs was this ventricle made as is apparent for they only have it who have lungs In caeteris which respire not but transpire only as fish have not this right ventricle So that this right ventricle and the lungs were made for the left 's sake Sinister is exactly in the middest of the heart Sinister Rotundus it 's narrower then the other for that it containeth lesse matter His cavity is round comes down to the point hath as much flesh as thrice the right for the better keeping of naturall heat and more solid that the vitall spirits vanish not Therefore it 's called Sinus spirituosus Sinus spirituosus arteriosus ventriculus In this cavity are made the vitall spirits which by the arteries with arteriall bloud are communicated to the rest of the body for his nourishment and refection Materies spirituum Aer externus sanguis The materialls are aire and bloud mixed together Aire received in by the mouth and nostrils prepared in the lungs and per arteriam venosam whilst the heat is dilated is carried into the left ventricle Bloud attenuated in the right ventricle partly into the lungs per venam arteriosam for their nutriment and partly per septum is drawn by the ventricle and retained there by his innate property mingled with the aire where by the in born faculty of the heart spirit and continuall motion it 's perfected and becomes vitall spirit and arteriall bloud which in the contraction of the heart is poured into the great artery for the life and nourishment of the whole body Superficies interna ventriculorum inaequalis The inward superficies of both ventricles is unequall and rough least spirits and bloud there entring before they be perfected should glide away And here to this businesse the valves concurre The unevennesse is partly ob foveas plures which in the left are remarkable and partly for fleshy bits Portiunculae which about the point of the heart thin and small in the right five or six in the left two thicker and stronger unto which the nervous fibres of the valve do grow Ligamenta cordis And these by some are called the ligaments of the heart This is the hottest according to Galen howsoever the Peripatetick will have the right Yet is it not so hot as to produce hairs as Pliny reports of Aristomenes Messen lib. 11.

Vlmus sanguinem arterialem to be prepared attenuated and concocted in the spleen thence into the Trunk of Aorta and so into the right ventricle of the heart where mingled with the aire prepared in the lungs But do not valves hinder this passage Varolus per Intestina Mercatus cum Columbo Varolus denies all passages to the left but only by the trunk from the Intestina Mercatus inclines to Columbus concerning the passage only the finer part to nourish the lungs and the thicker and grosser to come to the heart per Arteriam venosam and there refined for the rest of the body At each side of the Basis of the heart there is an Appendix which neither in regard of profit or action but from similitude is called Auricula Auricula which about the ventricles before the orifices of the vessels are placed to carry stuffe into the heart Dextra Dextra which is set before Vena Cava is greater and makes with Vena Cava as it were one common body It 's greater then the left and his point stands upward The Sinistra is placed ad Arteriam venosam Sinistra It 's much lesse because his orifice is lesser then that of Vena Cava It is likewise sharper longer in his side and more wrinkled in his externall superficies and more crested then the right harder but lesse fleshy and thicker because the ears must answer to their ventricles since they serve for a kind of preparation of matter They are hollow for the inlargement of their Sinus and have a peculiar substance not communicable to any other part they are cuticular Cuticulares least they break by attraction and for the better following the motion of the heart because when the heart is dilated they like skins are contracted and thrust matter to the heart when they are
Arteria Venosa foras intro spectant Foras intro ne refluat sanguis in Cavam to hold the bloud that in contraction of the heart it run not into the Cavam I wonder how Columbus mistakes himself who will have these valves with those of Arteria Venasa to serve for the emission of bloud as if they were intus foras But Piccolhominy reprehends him Since therefore this branch that enters the heart is lesser then that which ascends and that there are ports and stops in the Auricula dextra and right ventricle since no common passage from the lungs in Cavam whereby these branches might be spread through the whole body I cannot see that all bloud that is for nourishment comes first to the heart there to be perfected Vena arteriosa The other vessel of the right ventricle is Vena Arteriosa a vein by office because it carrieth bloud 2 Because it stirs an artery by substance for it 's like it having two coats It 's fixt with a lesse orifice then Cava hath to the right ventricle from whence as you have heard Vesalius say it ariseth when in respect of his connexion it is better said to be a branch of Aorta which is plain in foetu But in truth it 's begotten with the rest of the spermaticall parts His coates are thick and hard that they be not hurt by respiration neither ought they to be easily dilated which was for two reasons profitable 1. That the whole capacity of spirits might be free from the instruments of spirit 2. That bloud rush not violently into the heart And since the lungs were to be nourished with thin and vaporous bloud only the most thin is elaborated and being filled here by these thick wals is made here thinner for their fitter nourishment Besides to keep this right ventricle from cold aire for the branches of Aspera Arteria which drawing cold aire are carried between the branches Venae Arteriosae Arteriae Venosae whereby the aire drawn per Caeca spiracula is communicated Now if it had but one coat it should draw as much air as Arteria Venosa so at length the right might be extinguished Therefore he draws not more air then is fit for the refreshing of the spirits in the right ventricle Pividitur in duos ramos in dextrum sinistrum pulmonem Vsus Thus resting upon Arteria Magna is divided into two Trunks which are carried to the right and left lungs And these are disseminated into innumerable branches per Pulmones Use is in the contraction of the heart to take and carry a great part of the bloud out of the right ventricle for nourishment into the lungs In the body of this vessell there are three valves which intus foras spectant Valvulae tres intus foras sig moides dictae and every one like a half moon they seem to be so hard that they are like a round cartilage Arteria venosa is a vessel of the left ventricle Arteria venosa whence it was It is an Artery by office because if contains aire and carries it and hath pulsation which by sense cannot be perceived yet it is the more probable because it is continuated to the left ventricle It is a vein by substance his orifice is greater then that of Aorta It hath a thinand simple coat that the aire which comes from Aspera Arteria's branches may the better pierce and the laxe substance give way to the attraction of the aire into the heart for the better tempering of his heat and fuliginous vapours returned into Asperam Arteriam It is a great vessell and in his outlet from the heart divided into two branches as if it had two orifices The right runs under the Basis of the heart into the right lung the left like Vena Arteriosa into the left where it is divided into innumerable branches This and Aorta are joyned in their rise only there goes between them a certain piece which made a channell and was perforated in foetu Botallus observed between these valves of this part another which was alwayes gaping by which the bloud did flow and reflow in Venam Cavam Use is in dilatation of the heart to draw air out of the lungs Vsus corde dilatato trahere aeram è pulmonibus Contractio spiritus in Pulmones and in his contraction to carry a portion of vitall bloud with fuliginous vapours into the lungs And least all the air should goe back into the lungs at the orifice of this vessell there is a membranous circle out of Substantia Cordis which leads inward and is divided into two valves Duae valvulae Foras intus foras intus which are greater then those à Vena Cava and end in an obtuse point and are stronger and have longer filaments and more fleshy of which one respects the right side the other the left which joyned are like an Episcopall miter There are but two valves quia it was fit that it should not exactly shut 1. That since all parts want bloud and spirit the lungs might likewise have a continuall supply 2. Quia they only give a continuall passage to the avoiding of fuliginous vapours out of the heart since nature hath allotted no other part Bauhinus observed in 1611. Observatio Bauhini 1611. that from the Arteria Venosa there went out of the left ventricle a branch up to the left lung and so winding down by the side of the great artery under the midriffe was inserted into the emulgent a fit passage for the avoidance of matter out of the lungs into the Kidneys Riolanus gives three uses of this vessell Vsus 1. Aerem in Cor. 2. Fuligines exportare 3. Sanguinem in pulmones First to carry air into the heart 2. To bring forth the Purgamenta spiritus vitalis 3. To supply the lungs with arteriall bloud And these three are done by the same passage at one time neither doth the artery cease to beat Arteria Magna Venae pulsatiles Audaces Substantia Tunicae 2.1 Exterior tenuis sine sibris transversis Arteria Magna is the other vessell of the left ventricle Some call arteries Venas pulsatiles The Arabian Interpreters Venas audaces Of these there are three sorts Aspera Arteria Arteria Venosa Arteria Magna His Substance is membranous the fitter for distention It hath 2 particular coats The exteriour is thin and soft with many right fibres some oblique none transverse 2. Interior densa Interiour coat is five times as thick as that of the veins First that arteriall bloud and spirit evaporate not 2. That it be not cracked with the continuall motion of the Systole and the Diastole Cum sibris transversis tantum It hath only transverse fibres for the sudden distribution of bloud and spirit Galen puts another coat to it which is in the inward superficies like a cob-web They are without sense as veins are least they should
suffer by their continuall motion This great one hath his rise out of the left ventricle with a large mouth from whence by his contraction bloud and spirit elaborated in the left ventricle is conveyed with heat into the whole body and least in the dilatation they should run back into the ventricle nature hath put three valves in his orifice Tres valvulae intus foras Sigmoides Sigmoides intus foras vergentes as are in Vena Arteriosa but are greater and stronger quia the body of this artery is stronger then that of Vena Arteriosa These hinder the aliment drawn out of the guts by the Mesaraick arteries from coming to enter the heart In some creatures it is cartilagineous in some bony secundum Aristotelem Quia quod movetur movetur supra aliquo quiescente cui innititur dum movetur The branches of this artery come along with those à Porta and Cava yet sever with Cava As the veins which come to the skin have no arteries so in the substance of the muscles they are seldome seen with veins because the bloud is thinner and the spirits breathed from the arteries can come further without help of an artery Use of this great artery and his branches have a double consideration Vsus duplex 1. ut canales Ad spirituum vitalium retentionem c. 1. as they are pipes or channels 2. as they have pulsation As channels they are given to the parts for three causes 1. That they may hold spirituall and vitall bloud and distribute it through the whole body 2. To carry vitall spirits for the upholding of the parts 3. To transmit with the same spirit heat and vitall faculty through the whole bodie As they have pulsation 2. ut pulsatiles 1. Naturalem calorem fovere c. they have 3 uses 1. To preserve the naturall heat of the parts by saving it for otherwise it would be extinguisht 2. By his motion to hinder putrefaction in the veins for bloud else would soon putrefy 3. To shake the bloud into the substance of the parts whereby nutrition may be made This motion of the arteries is called pulsus Hic motus Pulsus which is perfected by dilatation and contraction and it is not insitus arteriis but flows à Corde as appears if you tie an artery beneath the ligature it moves not and are simul dilated and contracted with the heart Only in this they differ that the motion of the heart is greater and vehementer Arteries are close under veins not for safegard but that by his motion they may force bloud to come into the veins as likewise being dilated they draw from the veins and contracted cast it back again by the mutuall passages of the veins and arteries so likewise by their mouths terminated in the skin all fuliginous excrement they may avoid and draw a great part of aire into them And this is that that Hippocrates says Totum corpus foras introque spirabile est Hence is his necessity Neither was there any creature ever without a heart although the Auspices in Pliny did feign many creatures without hearts when they would deterre the Emperours from some enterprise De Pulmonibus RIolanus commands us that before we touch the heart we shew the vessels and then the lungs Yet with Bauhinus we bring the lungs in the last place These are the receipt of life spirit and aire for the refreshing of the heart and the instrument of respiration and voyce and given to those creatures quaerespirant and have a neck and therefore fishes quia non respirant want lungs and the left ventricle of the heart They are called 〈◊〉 〈◊〉 〈◊〉 〈◊〉 〈◊〉 quod est respirare Situs in the hollow of the chest Figura a little different from the mouth least by the sudden arrivall of the aire they should be too much cooled Yet in bodies with long necks where the aire comes not conveniently tempered we see a disposition to consumptions and dry diseases In the living whilst we draw in aire they fill the whole cavitie except the hollow between the coats of the Mediastinum whilest we expirare they fall but not so much as in dead bodies for that they are full of aire and bloud And although we use with bellows to blow them yet are they never so full as in the living because they are to hold aire for many motions of the heart as is plain in Divers and singers Connexus to the neck and back Connexus collo by the benefit of Aspera Arteria although the greatest part is free of them whereby they may more freely move and by the intervention of the Mediastinum they are tied before to the Sternum Sterno as likewise by certain fibres to the sides of the chest and Pleura behind to the vertebra Per fibras Pleura If too streightly tied it causes a difficulty in breathing Massa ne Cor deprimant Yet Massa says there is good use of these ties in regard of the heart least it should be crushed with the weight of the lungs They are likewise tied to the heart per venam arteriosam arteriam venosam Motus is diversly argued De motu secundum Aristotelem à Corde Galen ad fugam vacui Aristotle 3. de Part. Animal cap. 6. will have the motion of the lungs to be à Corde Galen will have them move non propria vi sed ad fugam vacui as appears in wounds of the chest the aire entring the lungs move not because the aire fills the empty place But the chest being whole the lungs necessarily are dilated to avoid vacuum Neither do they only fall as Bauhinus observes ad vacui fugam but either pressed by the chest or by the aire expired or by both they fall together Yet so as Nature ties them to the Pleura that they may follow the motion of the chest Laurentius ad motum Pectoris Laurentius will have them move non à Corde quia illius motus perpetuus non est nec vi propria sed per accidens they follow the motion of the chest Aver propria vi Averroes will have them move propria vi non thoracis motum sequi for so there might be granted a perpetuall motion Riolan motu insito Riolanus his motus is insitus and depends not from any other and is dilated and contracted like a bag not like a bellows for in a free breathing the chest standing still the lungs move quia respiramus And breathing is perfected by dilatation and contraction Figure is fitted to the parts they rest upon Figura ad cavitatem Pectoris Therefore without they answer the cavity of the chest and are extumescentes within they are hollow that they might the better yield with his lobes to the heart and be his covering The right joyned to the left represent the cloven foot of an oxe They are divided by the benefit of the
Mediastinum into Dextrum Sinistrum Dividuntur in dextrum sinistrum So that one side either hurt or lost the other may be of use as we see in consumed bodies where one side is quite gone yet they live by the benefit of the vessels that come from Aspera Arteria the heart Each Lung is divided by a line obliquely drawn transverse over against the fourth vertebra of the chest into two lobes In duos iobos the upper and the lower lobe yet so as they are tied by membranous fibres This is rather a note of section then division They are so divided the better to embrace the heart and lest in stooping they should be pressed Besides if they were continuated the length of the chest Ne dilatatio impediretur it would hinder the fit disatation and constriction These are sometimes called the Alae Alae because they are sometimes spread like wings They are three sometimes more often two and in those who have short chests quintus lobus is seldome found Substance is thin rare laxe spongy Substantia rara spongiosa In fâ—tu rubra and as it were made of the froth of bloud all for lightnesse and motion it 's woven with three sort of vessels and covered with a thin membrane which according to our years in softness colour and substance differ and the variety of our aliment for in faetu whilst the heart and lungs move not their substance is red but after having aereum alimentum they turn to a pale yellow In long sicknesses they grow spotted with dusky and black spots Membrana which invests it is from Pleura Membrana a Pleura Communis cum vasis and where the vessels enter the lungs ther their coats is common This is thin and light soft that it might be dilated and shut with more ease It is porous for the excretion of purulent matter in Pleurisies and Peripneumonia per anacatharsin tussiendo Superficies laevis His Superficies is smooth and as it were drawn over with a slipperie humour Nervi are but small Nervi exiles because the lungs need but little sense they are form the sixt pair and enter not the flesh of the lungs lest their continuall motion might breed pain Hence it appears that all the lungs are without pain Vasa Vasa three sorts which no other part hath It hath Asperas Arterias veins from Vena Arteriosa and smooth arteries from Arteria Venosa and all three have their peculiar action The Bronchia Asperae Arteriae are placed between the veins and the arteries which are a-crosse into the lobes on both sides and so end in capillares The first vessell is proper to the lungs of which we will speak next The other comes from the heart of which we have already spoken Yet some considerations we will adde as that the Vena Arteriosa serves the naturall faculty the Arteria Venosa the vitall and Aspera Arteria the Animall The two vessels are farre greater then the lungs bignesse may seem to require if we proportion them with other parts Yet in respect of the continuall motion of the lungs they quickly consume much nourishment Besides they not only carry naturall bloud and vitall with vitall spirit but also by their own extremities and the extremities Asperae Arteriae they are a receipt for air and bring it into the ventricles If but a small branch of this is broken the lungs grow purulent We will here adde a rule of Fernelius Fernelii consilium that in passions of the lungs we should open the liver-veine of the left arm quia the veins of the lungs come from the right ventricle of the heart and this is derived from the left side of Vena Cava which runs by the left lobe into the armes For the best evacuation is secundum rectitudinem fibrarum But the lungs receive not bloud from Cava but from Vena Arteriosa yet emptying Vena Cava ad fugam vacui says Riolanus you empty the lungs Concerning their nourishment it is different from that of other parts as their substance is different for as their substance is the thinnest so is their nourishment the most pure and thin In other parts their coats are thin and fine whereby the thick bloud may be distributed to their parts that are about them For the body is nourished with the bloud it draws through the coats of the vessels The arteries are thick and dense whereby a small quantity of thin and vaporous bloud may be drawn for the maintenance of life But in the lungs the coats of the veins are thick that only the finest may come through that the aliment might answer his part and the arteries thinto effuse and breath plenty of fine and thin vitall bloud So that here the artery hath the coat of a vein to give plentifully sanguinem spirituosum So that what the vein by his thickness keeps back the artery with his thinnesse may recompense Concernign the motion of the arteries of the lungs it is the same with that of Magna Arteria Use First to refresh the heart whilest the air passeth per Asperam Arteriam Vsâ—â—d Cord s refrigeriâ—m and so by his common Anastomoses with Arteria Venosa into the heart at his dilatation So that they prepare it that it come not foule or impure or cold to the heart 2. To be instruments of voice and respiration And unto these you may reduce the six uses propounded by â—d vocem respirationem Piccolhominy De Aspera Arteria THe third vessell proper to the lungs is Aspera Arteria a name from his unequall substance and to distinguish it from the smooth arteries Canna pulmonis It 's commonly called Canna Pulmonis It 's a hollow pipe and greatest in all that have lungs Situs Before the Gullet Situs ante Oesophagum ad laryngem in the lower part of the fauces and so open it 's carried into the lungs His lower part is divided into many pipes the larynx is head which is to be spoken of in the history of the mouth Connexus Connexus faucibus above by the help of the inward coat to the jaws by the externall before and at the sides to the muscles and vessels behind with certain fibrous ties Oesophago that his descent might be the safer Substance is partly membranous Substantia partim membranes partim cartilaginia Duaetunicae Interna partly cartilagineous It hath two coats from Pleura and annexed strongly by the membranous ties of the cartilage and like a hard pipe and by this coat is tied to the neighbour parts and joyns and separates the recurrents Interna is stronger and comes from the coat which invests the Palate to defend it from all sharp vapours distillations or purulent matter His length is woven with right fibres soft and smooth and lined as it were with an unctuous humour that it be not dried with great heats and

hath most use of spirit Substance is not altogether bony Substantia non tata ossea nec carnea as is the scull so all motion should be lost nor all fleshy as is the lower belly so all parts might fall in together and so cause suffocation Therefore Nature hath provided an instrument with an intercourse of flesh and bones so that by the bones an equall amplitude iâ—preserved and by the muscles a freedome of motion is maintaied Therefore having placed this great Prince the Heart in the chest she presently set a guard about it for his defence and security which was to be preserved by cold aire Therefore she put him into a moveable castle that by his spreading aire for his refreshing might be drawn into the lungs and by his contraction fuliginous vapours and smoaks might be expelled The Chest is divided into parts containing and contained Partes continentes conentae communes propriae Propriae durae out melles Containing are either common or proper The common are our first five

drawn together the valves are dilated because they are moved in a distinct time The reason saith Galen is because when the heart is distended it 's filled the ears when they are filled are distented Extended they are smooth and equall contracted they wrinkle within they answer to the unequall superficies of the ventricles They are thin the fitter for contraction Tenues they are soft and nervous for strengths sake for that is strongest that is most nervous Hippocrates in lib. de Corde in sectione vivorum observed the motion of the heart ceased yet these to move Galen in 7.
