1). What are the functions of an artery
Ans: maintain blood pressure even when the heart relaxes ; carries out blood

Ans: returns deoxygenated blood back into heart
3). What the functions of the arteriole
Ans: transports blood from arteries to capillaries
4). What are the functions of the venue
Ans: a very small blood vessel, always allows blood to return from capillary beds to
drain into larger blood vessels.
