Question:-

how gaseous exchange occurs in alveoli?

${\red{\underline{\underline{\bold{Answer:-}}}}}$

Gas Exchange:-

• Gas exchange is the ‘exchange’ of oxygen and carbon dioxide in the lungs.

• But it actually happens in a very specific part of the lungs, the Alveoli.

• The Alveoli, are located on the bronchioles and are surrounded by capillaries, tiny blood vessels.

• When you breathe in the Alveoli get filled with air, which has oxygen,

• making the concentration of oxygen in the Alveoli be higher than in the blood vessel surrounding it,

• therefore it diffuses into the blood vessel.

At the same time, carbon dioxide in the blood diffuses into the Alveoli and is exhaled out.
