Breathing (or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide. The body's circulatory system transports these gases to and from the cells, where "cellular respiration" takes place.
