III. Parts and Functions

This waste and extra water becomes urine, which is stored in the bladder. * Pancreas - The pancreas plays a role in digestion, as well as in hormone production. * Ovary - In addition to containing the egg cells necessary for reproduction, the ovaries also produce estrogen and progesterone. * Testes - The testes produce testosterone and sperm.
