But the present opinion is, — thatthe blood undergoes some change in it, which renders it useful in thesecretion of the bile ; and this opinion derives support from the greatquantity of hlood with which this organ is known to be supplied, andfrom its vein passing to the vena porta. I have added the following diagram, to point out thebranches which take their origin from the descending orta. THE DISSECTORS GUIDE. 171 It was necessary to make a division in the diagram, to pre-vent the numerous branches becoming complicated. The thoracic aorta, in the posterior mediastinum, sendsoff ten pair of intercostal arteries, aesophageal branches tothe oesophagus, and bronchial branches to supply the struc-ture of the lungs. 17 3184187 5 8. 1. The abdominal aorta, immediately after having passed between thecrura of the diaphragm, sends off _ , 2 The inferior phrenic artery. Occasionally, this vessel arises iromthe cceliac, and sometimes there are two trunks arising from the aorta. 3. The ccelic artery, arising from the left side of the aorta; it tormsan axis, which gives off three branches. 4. The coronaria ventriculi. 5. The splenic artery. 6. The hepatic artery. ;The coronaria ventriculi passes forwards to the cardiac orifice of the stomach, where it divides into 172 the dissectors guide. 7. The posterior coronary, which supplies the posterior surface of thestomach, sending off 8. The cardiac branch, to supply the cardiac orifice. 9. The anterior coronary, supplying the anterior part of the branch sends off 10. A branch to supply the pyloric o
