How the Heart Works

The heart is a strong and muscular organ that is about the size of a fist in adults. It pumps blood throughout the body and is located behind the breastbone between the lungs. Deoxygenated blood flows from the heart to the lungs where it gives up carbon dioxide and is freshly oxygenated. From there, the blood returns to the heart and is pumped to the rest of the body.
