'''Lungs''' are organs that are in the chest. Humans have two of them. They contain the bronchioles, the alveolar ducts and the alveoli. They can hold about 6 liters of [[air]].

Lungs' main job is to make [[oxygen]] available to the body and to remove gases, such as [[carbon]] dioxide. The right lung has three sections, called lobes, and is a little larger than the left lung, which has two lobes. [http://my.clevelandclinic.org/anatomy/lung/hic_How_Your_Lungs_Work.aspx]
