## What function makes a heart?

The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. “The tissues of the body need a constant supply of nutrition in order to be active,” said Dr.
