Answers

Answered by llJahangirll

Answer:

The heart pumps oxygen-rich blood to the rest of the body through one main artery called the aorta. The muscular walls of the aorta and the other arteries help the heart pump blood. When the heart beats, arteries expand as they fill with blood. When the heart relaxes, the arteries contract.
