Cardiovascular (Blood Vessels) & Respiratory System Diagrams for Test

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