Explanation:
The smallest bronchioles end in tiny air sacs. These are called alveoli. They inflate when a person inhales and deflate when a person exhales. During gas exchange oxygen moves from the lungs to the bloodstream. Gas exchange allows the body to replenish the oxygen and eliminate the carbon dioxide.
