  1. Lung

    The lung is the essential respiration organ in many air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located near the backbone on either side of the heart. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. A large surface area is needed for this exchange of gases which is accomplished by the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs called alveoli. To properly explain the anatomy of the lungs, the passage of air through the mouth to the alveoli needs to be looked at. The progression of air through either the mouth or the nose, travels through the oropharynx, nasopharynx, the larynx, and the trachea. The air passes down the trachea, which divides into two main bronchi and these branch to the left and right lungs where they progressively subdivide in a system of bronchi and bronchioles until the alveoli are finally reached, where the gas exchange of carbon dioxide and oxygen takes place. Breathing is driven by muscular action; in early tetrapods, air was driven into the lungs by the pharyngeal muscles via buccal pumping, which amphibians still use. Reptiles, birds and mammals use more of the musculoskeletal system.
