Detailed explanation-2: -This exchange of oxygen and carbon dioxide is called respiration.
Detailed explanation-3: -External respiration describes the exchange of gasses between the external environment and the bloodstream. The components of external respiration include alveolar surface area, ventilation and perfusion matching, and partial pressure gradients.
Detailed explanation-4: -External respiration, also known as breathing, involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation). During internal respiration, oxygen and carbon dioxide are exchanged between the cells and blood vessels.
