Contrast internal and external respiration.
|
External respiration is the process of gas exchange that occurs in the lungs. Oxygen enters the pulmonary capillaries; carbon dioxide leaves the blood and enters the avioli. Factors influencing this process include the partial pressure gradient, the thickness of the respiratory membrane, surface area available and the matching of aveolar ventilation and pulmonary perfusion.
Internal respiration is the gas exchange that occurs between the systemic capillaries and the tissues. Carbon dioxide enters the blood, and oxygen leaves the blood and enters the tissues. |
