The circulatory system, also known as the cardiovascular system, is the intricate network responsible for transporting blood, nutrients, oxygen, and hormones throughout the body. Comprising the heart, blood vessels, and blood itself, this system plays a vital role in maintaining the body's overall function and equilibrium. The heart pumps oxygenated blood to various tissues and organs through arteries, while veins return deoxygenated blood back to the heart for oxygen replenishment in the lungs. Additionally, the circulatory system aids in immune response, waste removal, and temperature regulation. It serves as the life-sustaining highway, ensuring the delivery of essential substances to cells and tissues and facilitating the removal of waste products, thereby supporting the body's dynamic balance and vitality.
