How Does the Circulatory System Function?

The circulatory system, also known as the cardiovascular system, is responsible for transporting blood, oxygen, and nutrients throughout the body. It consists of the heart, blood vessels, and blood. The heart pumps oxygen-rich blood to the body's tissues through arteries, while veins carry oxygen-poor blood back to the heart. Capillaries, the smallest blood vessels, facilitate the exchange of oxygen and nutrients with the body's cells. This continuous cycle ensures that the body receives the necessary oxygen and nutrients for survival. Understanding the circulatory system is crucial for comprehending how the human body functions.
