External respiration refers to the exchange of gases (oxygen and carbon dioxide) between the air in the lungs and the blood in the pulmonary capillaries. Pulmonary ventilation is the movement of air in and out of the lungs, while breathing generally refers to the entire process of gas exchange and includes both pulmonary ventilation and external respiration. Internal respiration refers to the exchange of gases between blood and body cells, and cellular respiration refers to the metabolic process of producing ATP within cells.
