The human heart pumps blood throughout the body to provide nutrients and oxygen to tissues and organs. It pumps approximately 7,600 liters of blood per day through the 96,000 blood vessels in the human body. Maintaining a healthy heart requires avoiding smoking and eating a nutritious diet, as well as engaging in regular physical activity to keep the heart and blood vessels strong.
