Question

Quizplus · Accepted Answer

Internal respiration refers to the exchange of gases, specifically oxygen and carbon dioxide, between the bloodstream and tissues. It takes place within the mitochondria during cell respiration, which uses oxygen to produce energy, but it is not another name for cell respiration. Passage of air through the lower respiratory tract is external respiration.
