Expert Solution
Step 1: Introduction
The heart is a four-chambered (two auricles on top and two ventricles on bottom) organ of the cardiovascular system. Oxygenated blood is collected in the left chambers of the heart and deoxygenated blood is drained into the right chambers of the heart through the superior and inferior vena cava.
The lung is a pulmonary organ that plays a major role in the inspiration and expiration of air. Contraction of diaphragm located beneath lungs creates negative pressure which leads to inhalation of air. Similarly, relaxation of the diaphragm results in contraction of lungs and exhalation.
