Question

The exchange of oxygen and carbon dioxide between air in the alveoli and blood in the pulmonary capillaries is called _____.​

Quizplus · Accepted Answer

External respiration refers to the exchange of gases between the environment and the body, specifically between the air in the alveoli of the lungs and the blood in the pulmonary capillaries. Internal respiration, on the other hand, refers to the exchange of gases between the blood and the body's tissues, while cellular respiration refers to the intracellular process of converting glucose and oxygen into ATP and releasing carbon dioxide as a waste product. Oxidation is a chemical process that involves the loss of electrons from a substance.
