Metabolism of nutrients by body cells produces various wastes such as carbon dioxide and nitrogenous toxins (creatinine, urea, and ammonia), as well as imbalances of water and essential ions. These metabolic wastes and excesses must be eliminated from the body. Essential substances are retained to ensure proper body functioning. Although several organ systems are involved in excreting (getting rid of) toxic cellular wastes, the urinary system bears the primary responsibility for removing nitrogenous wastes from the blood. In addition to this purely excretory function, the kidneys maintain the electrolyte, acid-base, and fluid balances of the blood. Thus, kidneys take care of your blood and are major homeostatic organs of the body. Malfunction of the kidneys leads to a failure of homeostasis, resulting (unless corrected) in death. 1. Complete the statements (hint: read paragraph above): The kidney is referred to as an excretory organ because it excretes also a major homeostatic organ because it maintains the electrolyte, balance of the blood. Urine is continuously formed by the wastes. It is and and is routed down the by the mechanism of to a storage organ called the Eventually the urine is conducted to the body exterior by the In males, this tube-like structure is about inches long; in females, it is approximately inches long.
