what is the difference between the internal and external respiration?

Question

Sefton · Answer

Internal respiration happens inside the body, specifically between blood and cells. Oxygen is delivered from the blood to body cells, while carbon dioxide is picked up from cells to be carried away.External respiration happens in the lungs between air and blood. Oxygen enters the blood from the lungs, and carbon dioxide leaves the blood to be exhaled.
