The blood is a fluid absolutely indispensable to life. It is responsible for the transportation of all nutrients to cells and tissues in the body. A very important segment in this process represents the cardiovascular system, also known as the circulatory system. The main blood vessel from the body is the aorta. This is the widest blood vessel which branches into several different arteries to serve all tissues in the body. Since the requirements for nutrients and oxygen differ according to species, we considered interesting to realise a synthesis of aortic branches, namely its ascending part and the aortic arch (Arcus aortae) in humans, swine (Sus scrofa domestica) and equine (Equus caballus). The present study involves the systematic evaluation of each vascular aortic segment focusing on: the confirmation of the presence of ascending aorta and aortic arch; similarities regarding the number and origin of collateral arteries. Following the review of the literature we found numerous differences in the studied species. First, we noted the absence of ascending aorta segment in pigs compared with humans and horses, where it is present. Further we identified differences regarding the coronary arteries (Aa. coronaria), differences that implies the origin of the artery openings. There were also different numbers of collaterals branches in the aortic arch: 3 in human, 2 in swine and only one in equine. Another interesting observation was the origin of carotid arteries from pigs and horses which is represented by the bi-carotid trunk, segment that is missing in humans.
