The capillaries, which permit theexchange of substance between the blood and body tissues. And theveins, which return blood from the tissues back to the heart.

2. In order to maintain the homeostasis in thecardiovascular system and provided adequate blood to the tissue,blood flow must be redirected continually to the tissue as theybecome more active. Three homeostatic mechanisms ensure adequateblood flow, blood pressure and distribution are neural, endocrineand autoregulatory mechanism.
