A human heart weighs between 200 g - 450 g, however approximately 300 g. A woman’s heart beats faster than a man’s. In under a minute, your heart can pump blood to every cell in your body. Every day, your heart beats about 100,000 times, sending 2,000 gallons of blood surging through your body. Although it’s no bigger than your fist, your heart keeps the blood flowing through the 60,000 miles of blood vessels that feed your organs and tissues.
