Explain how the right side and left side of the heart cooperate as a double pump
What will be an ideal response?
The heart is divided functionally into right and left sides. The right side of the heart is sometimes called the pulmonary pump while the left side of the heart is sometimes called the systemic pump. The right side of the heart pumps blood into a series of blood vessels leading to and within the lungs for gas exchange, collectively called the pulmonary circuit. The left side of the heart receives oxygenated blood from the pulmonary veins and pumps it into the blood vessels that serve the rest of the body through the systemic circuit for another gas exchange event.
