What's external respiration?

The exchange of oxygen and carbon dioxide between the air inhaled into the lungs and the blood flowing through the pulmonary capillaries.

11

What's internal respiration?

the exchange of oxygen and carbon dioxide between the blood in the capillaries all over the body and all of the cells and tissues
