This video describes the functions of the excretory system, which is critical to survival. The many living cells in the human body produce metabolic wastes, which must be eliminated from the body. These wastes include carbon dioxide, urea, water, water vapor, and salts. The four organs that make up the excretory system are the lungs, kidneys, liver, and skin.
