Cardiovascular (Blood Vessels) & Respiratory System Diagrams for Test

The systemic and pulmonary circulations. KEY: =Oxygen rich, CO 2 -poor blood =Oxygen poor, CO 2 -rich blood Capillary beds of lungs where gas exchange occurs Pulmonary veins Pulmonary arteries Pulmonary Circuit Aorta and branches Left atrium Left ventricle Venae cavae Capillary beds of all body tissues where gas exchange occurs Systemic Circuit Right atrium Right ventricle
