Pulmonary Ventilation.
External Respiration.
Internal Respiration.
Pulmonary Ventilation is the movement of air into and out of the lungs so that the gases there are continuously changed and refreshed (commonly called breathing).
External Respiration is the movement of oxygen from the lungs to the blood and of carbon dioxide from the blood to the lungs
Internal Respiration is the transport of oxygen from the lungs to the tissue cells of the body, and of carbon dioxide from the tissue cells to the lungs. This is accomplished by the cardiovascular system using blood as the transporting fluid.
