What are the main functions of the human heart?

The human heart serves as the core of the circulatory system, with its main function being to pump oxygenated blood throughout the body. It consists of four chambers - two atria and two ventricles - which work together in a rhythmic pattern to ensure proper blood flow. The atria receive deoxygenated blood and pump it into the ventricles, which then contract to pump the oxygen-rich blood out to the rest of the body. Additionally, the heart maintains proper blood pressure by adjusting the force of its contractions, allowing it to deliver blood efficiently to various organs and tissues. By performing these crucial functions, the heart ensures a continuous supply of oxygen and nutrients to support the overall functioning of the body.
