Expert Solution

Step 1

Humans have a four-chambered heart with two atria and two ventricles that work as a dual pump to supply blood to all body organs and tissues. The heart is the primary muscle of the cardiovascular system. Since the vital component is frequently carried by the blood, which the heart pumps, there must be enough blood flow for each organ, tissue, and cell in the body to function normally medically.
