Hello, today I explain the parts of the respiratory system.
00:00:02
The larynx, the trachea, the bronchi, the lungs, the bronchiolus and the air sacs.
00:00:09
And the solution is, we take air and the air runs down to the larynx and the trachea.
00:00:21
In the bronchi goes to the lungs and to the bronchials and takes space in the air sacs.
00:00:32
In their sense, change the oxygen to the CO2, and the CO2 runs to the bronchi and the trachea, and we sputum.
00:00:50
When we breathe, the air goes down to the trachea and roaches, goes to the lungs, goes to the roaches, goes to the air sacs.
00:01:07
And in the air sacs, it spells CO2 and takes oxygen and runs up all the way back.
00:01:24
Hello, today we will explain the gas exchange. The gas exchange happens in the air sac.
00:01:32
This is the red part. This is the air sac.
00:01:44
The capillaries express the CO2 and take the O2, and the O2 goes to all parts of the body.
