Cells complete essential activities of the body by consuming energy, such as growth and repairing damaged tissues. In a single organism, cells often work simultaneously. For example, when you are reading this article, not only are your eye and brain cells working, but other cells in your body are also active. Your intestinal cells are digesting food, and blood cells are transporting compounds within your body. If you get injured at this time, some cells will come to "repair" the wound.
