Heart, Front View
Because every cell in the body must have a never-ending supply of oxygenated blood, the heart never stops beating throughout a person's lifetime. It beats about 100,000 times a day, pumping 6 quarts of blood through the 65,000 miles of vessels that comprise the adult circulatory system, three times every minute.
