The lung is an organ in many vertebrates (animals having a spine, or backbone). It gives blood oxygen from the air, and takes away carbon dioxide. Most vertebrates have 2 lungs.

In animals, the lungs are the area where respiration takes place. Without respiration in the lungs, animals would not survive as the body cells would not be able to receive the oxygen needed.
