To do this it eliminates, among other things, the surpluses of certain minerals, called electrolytes, and returns to the blood the substances that are useful for the proper functioning of the organism (reabsorption).
Every day, a human being produces 800 to 2,000 milliliters of urine. The urinary tract is included in the excretory system (as the large intestine and the lungs).
This apparatus is a succession of retro- and subperitoneal organs: the two kidneys, the two ureters, the bladder and the urethra.
