Neither Internal Respiration nor Cellular Respiration Occurs in the Lung

Question

Neither internal respiration nor cellular respiration occurs in the lung.

Accepted Answer

Internal respiration refers to the exchange of gases (oxygen and carbon dioxide) between the blood and the body's tissues, and cellular respiration refers to the process by which cells convert glucose and oxygen into energy. Neither of these processes occur in the lung; rather, the lung is where gas exchange occurs between the air we breathe in and the blood.
