Where does the external respiration process take place?

Answer 1

External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.

Answer 2

External respiration takes place in the lungs, specifically in the alveoli where oxygen from the air is absorbed into the blood and carbon dioxide is released from the blood into the air sacs to be exhaled.

Answer 3

It's the interaction between the lungs/gills and the environment. So, in the lungs.

Answer 4

In the lungs, you enter oxygen into your body & that oxygen goes to the alveoli, which are in the lungs. So, it's in the lungs.

Answer 5

External respiration, commonly known as breathing, takes place between the lungs (gills, or trachea)and the atmosphere, just at the respiratory surface.
