Which organ contains alveoli? Options: Arteriole, Esophagus, Lung, Larynx

Back

Lung

Answer explanation

The alveoli are tiny air sacs located in the lungs where gas exchange occurs. Therefore, the correct answer to which organ contains alveoli is the lung.

Front

Identify the thin membrane that covers the lungs.

Back
