Question

Exchange of gases in the human breathing system takes place in the?​

Answer 1

alveoli

Explanation

During gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Answer 2

Required Answer :-

The exchange of gases takes place in the alveoli.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Additional information :-

• Alveoli are microscopic air sacs.

• They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.

• Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.

• CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.

• Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.

• Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.
