Explanation:

The heart is a muscular organ roughly the size of a closed fist. It sits in the chest, slightly to the left of center. As the heart contracts, it pumps blood around the body. It carries deoxygenated blood to the lungs where it loads up with oxygen and unloads carbon dioxide, a waste product of metabolism.
