Quizplus · Accepted Answer

Internal respiration refers to the exchange of gases (oxygen and carbon dioxide) between the cells of the blood and tissues. This process occurs through diffusion, where oxygen moves from the blood to the cells and carbon dioxide moves from the cells to the blood. Inhalation and exhalation refer to the movement of air in and out of the lungs, while external respiration refers to the exchange of gases between the lungs and blood.
