There are two lungs in the chest cavity, one on each side of the heart. When you breathe in, you inhale oxygen. When you exhale, you breathe out again and carbon dioxide is released into your lungs.

Its main centers are the brain and the spinal cord. Together they are called the Central Nervous System.
