Cardiopulmonary Quiz 1 Practice
Cardiac and pulmonary diseases are conditions that affect the lungs and heart. Over the week we have been able to cover some aspects of the cardiovascular system and the cardiopulmonary quiz one is designed to keep your mind fresh on what we learnt. Give it a shot and good luck!
