The aorta is the root systemic artery. It receives blood directly from the left ventricle of the heart via the aortic valve. As the aorta branches, and these arteries branch in turn, they become successively smaller in diameter, down to the arteriole.

Blood from the aorta passes into a branching system of arteries that lead to all parts of the body. It then flows into a system of capillaries where its exchange functions take place.

Many other such allometric scaling laws are known which relate lengths (such as the radius of the aorta, genome size) and time-scales (heart-rate, lifespan, reaction rates) to mass.

The anterior chamber of the early embryo's heart which functions to connect the ventricle to the ventral aorta. Synonyms: bulbus cordis, conus arteriosus, truncus arteriosus.

For example, people with Marfan syndrome may be tall, thin, have long legs, arms and fingers, and may be nearsighted. Their connective tissue is defective. If unrepaired, the connective tissue surrounding the aorta will eventually rupture and kill ...
