Question

Quizplus · Accepted Answer

Internal respiration describes the exchange of gases (oxygen and carbon dioxide) within the cells of all the body's organs and tissues. This process involves the uptake of oxygen by the cells for cellular respiration and the release of carbon dioxide, which then enters the bloodstream for transport back to the lungs for elimination. Alveolar exchange and external respiration both involve the exchange of gases between the respiratory system and the environment, while intercellular exchange is a more general term and does not specifically refer to gas exchange.
