Heart/Lung Facts

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.

The lungs are a pair of highly elastic and spongy organs in the chest. They are the main organs involved in breathing. They take in air from the atmosphere and provide a place for oxygen to enter the blood and for carbon dioxide to leave the blood. The lungs are divided into sections, with three on the right and two on the left.
