system organs help transport urine or store urine and release it when it is time. The organs of the urinary system include the two kidneys‚ two ureters‚ a urinary‚ bladder‚ sphincter‚ and the urethra. The kidneys are two bean-shaped organs‚ each about the size of a fist.

Excretory System Review Main Concepts: Describe the major gross anatomical structures of the excretory system. Kidneys: receive about 25% of the cardiac output; produce urine (a fluid containing water‚ ions‚ and small soluble compounds) Ureters: receive urine from the kidneys and conduct it to the urinary bladder. Urine movement involves a combo of gravity and the peristaltic contractions of smooth muscle in the walls of the ureters Urinary Bladder: receives and stores urine prior to elimination
