Simple Circulation Occurs in organisms with CS Closed There is presence of an atrium & a ventricle
Functions of the Cardiovascular System ¬Transport of O2, nutrients & wastes ¬Intervention at the balance of acids & bases, salts & water ¬Regulation of body temperature ¬Take self defense system, clotting & healing ¬Transportation of chemical messengers
Cardiovascular System components Heart 2 atria 2 ventricles
