The heart is an amazing organ. It pumps oxygen and nutrient-rich blood throughout your body to sustain life. This fist-sized powerhouse beats (expands and contracts) 100,000 times per day, pumping five or six quarts of blood each minute, or about 2,000 gallons per day.
Your heart is a key part of your cardiovascular system, which also includes all your blood vessels that carry blood from that carry blood from the heart to the body and then back to the heart.
