The Main Function of the Lungs

Abstract

The main function of the lungs is the exchange of gases: the absorption of oxygen from the environment and the removal of carbon dioxide from the body. These processes are necessary for cellular metabolism. Effective gas exchange is possible with the integration and coordination of the functions of various organs. The outside air is pumped to the lung surface through which gas exchange takes place, while the alveolar gas, "loaded" with carbon dioxide, is removed from the lungs using the same pumping mechanism.
