Answer:
alveolus
Explanation:
The bronchi deliver oxygen-rich air to the lungs, where gas exchange occurs in tiny air sacs called alveoli. Exhaled air (oxygen-poor and carbon dioxide–rich) go the reverse way—from the ends of the bronchioles and back up. ... The respiratory membrane is the barrier through which oxygen and carbon dioxide are exchanged.Jul 12, 2013
