Answer 2

Explanation:

The aorta is the main artery that carries blood away from your heart to the rest of your body. After the blood leaves the heart through the aortic valve, it travels through the aorta, making a cane-shaped curve that connects with other major arteries to deliver oxygen-rich blood to the brain, muscles, and other cells.

A large vein that carries blood to the heart from other areas of the body. The vena cava has two parts: the superior vena cava and the inferior vena cava. The superior vena cava carries blood from the head, neck, arms, and chest.
