Answer 2

Answer:

A blood vessel is a tube that carries blood. Oxygen rich blood leaves the left side of the heart and enters the aorta. The aorta branches into arteries, which eventually branch into smaller arterioles. ... The vena cava are the two largest veins that carry blood into the right upper chamber of the heart (the right atrium).
