It is separated from the ventricle by the aortic valve, that consists of three semilunar cusps; the right, left and posterior cusp.

What is the largest part of the aorta?

The descending aorta is the largest part of the aorta. It arises as a continuation of the aortic arch after the branching of the left subclavian vein. As previously mentioned, the descending aorta is divided into the thoracic aorta and the abdominal aorta, which are anatomically separated by the diaphragm.

What are the two arteries that supply the heart?

The ascending aorta gives off two arteries, which, albeit few, are very important. These are the left and right coronary arteries that provide arterial supply to the heart. These arteries spring out of the origin point of the ascending aorta, a segment referred to as the aortic root. The aortic root contains three aortic sinuses, which are dilatations of the aortic wall found just above the cusps of the aortic valve. Viewed from above, these sinuses resemble three well defined rounded pockets that meet at the center of the aortic lumen. The aortic sinuses, also known as Valsalva sinuses, are named according to their position as the anterior, left posterior, and right posterior aortic sinuses.

Is the aorta a straight path?

The aorta basically delivers oxygenated blood to all components of the body via the systemic circulation and thus, needs to be normal to deliver blood to the organs. In most individuals, the aorta pursues a moderately straight path.

Overview

Structure

In anatomical sources, the aorta is usually divided into sections.
One way of classifying a part of the aorta is by anatomical compartment, where the thoracic aorta (or thoracic portion of the aorta) runs from the heart to the diaphragm. The aorta then continues downward as the abdominal aorta (or abdominal portion of the aorta) from the diaphragm to the aortic bifurcation.
