THE CIRCULATORY SYSTEM

The circulatory system is a complex network responsible for transporting blood throughout the body, ensuring that oxygen and nutrients reach various tissues and organs. Central to this system is the heart, a muscular organ composed of cardiac muscle, which pumps oxygenated blood from the left side and deoxygenated blood from the right side.
