Urinary System

The urinary tract (also called the excretory system) consists of the parts of the body that makes, stores and excretes urine. Urine contains waste from the blood that must be eliminated from the body.

The urinary tract includes a pair of bean-shaped kidneys (which filter waste from the blood and produce urine), two ureters (tubes through which urine leaves the kidneys and travels to the bladder), a bladder (where urine is stored), and the urethra (the tube that carries urine from the bladder out of the body).

Definitions:

bladder - a hollow organ that stores urine until it is excreted. kidney - two bean-shaped organs that take waste from the blood and produce urine. ureter - two tubes, each of which carries urine from a kidney to the bladder. urethra - the tube that carries urine from the bladder out of the body.
