4. Urinary System Our bodies produce several kinds of wastes, including sweat, carbon dioxide gas, feces (also known as stool), and urine (pee). These wastes exit the body in different ways: Sweat is released through pores (tiny holes) in the skin. Water vapor and carbon dioxide are exhaled (breathed out) from the lungs. And undigested food materials are formed into feces in the intestines and excreted from the body as solid waste in bowel movements.
