In the inhalation, air enters through the nose, goes to the pharynx, travels down the larynx and the trachea and reaches the lungs through the bronchi. In the lungs, it runs down the bronchus to reach the eye sacs when gas exchanges take place.

When the air enters in the air sacs, the air exchange takes place.
00:00:31
This means that when we exhalate, we exhalate CO2 in the step of oxygen.
00:00:40
The CO2 comes from the circulatory system that takes the CO2 from the cells of the body
00:00:46
and when they arrive to the lungs and achieve the air sac, it takes the oxygen and expels the CO2.
00:00:51
And the CO2 goes out of the air sac.

Exhalation.
