What does urine do?

Urine is the end product of the body's filtration process, which removes waste and excess water from the blood. The main components of urine are water, urea, creatinine, uric acid, and other electrolytes. Urine also contains small amounts of other substances, such as hormones and proteins.

The kidneys produce urine by filtering blood and removing waste products. The filtered waste products are then transported to the bladder, where they are stored until they are eliminated from the body through urination.

Urine serves a number of important functions in the body:

* It helps to regulate the body's fluid and electrolyte balance.

* It removes waste products from the blood.

* It helps to maintain the body's acid-base balance.

* It transports hormones and other signaling molecules throughout the body.

Urine can also be used as a diagnostic tool to assess kidney function and other medical conditions.
