Illustration of the airways of a lung. The bronchus (top right) divides into many bronchioles. The bronchioles further divide, becoming smaller, and terminate in tiny air sacs, called alveoli (round). The lungs are the site of gaseous exchange; oxygen enters the blood and carbon dioxide is removed. | |
