External respiration is a physical process in which oxygen is taken up by capillaries of lung alveoli and carbon-dioxide is released from blood.

Internal respiration isabout ensuring the transport of oxygen in the blood from the lungs to the cells, and the transport of metabolic carbon dioxide from the tissue cells into the blood and to the lungs.
