Urinary System (Part 2)

The kidneys rid the body of the waste products of protein metabolism in the form of urea and maintain a balance of salts, water, and other substances. The kidneys unusual approach for ridding the bloodstream of unwanted substances is to essentially throw nearly everything out and then absorb back what the body needs. The three basic functions of the kidneys filtration, excretion, and absorption are carried out by nearly 2 million "filtering" units called nephrons.
