The urinary System
The urinary system is a system responsible for extracting waste components from the blood and expelling them from the body. Excretion is a process where the body gets rid of waste materials, such as urine. This system usually consists of six organs. The kidneys are the main organs of this system and are responsible for extracting waste components from the blood by using a filtration process. Once the wastes have been extracted by the kidneys, the urinary tract then eliminates and expels them from the body in the form of urine.
Functions of the urinary system
1. Produces, stores, and eliminates urine.
2. Filters the blood and returns most of the water and solutes to the bloodstream.
3. Regulates blood pressure.
4. Produces erythropoietin.
5. Keeps chemicals in balance.
