What is the function of the respiratory system?

3
00:00:30,129 --> 00:00:36,130
The respiratory system is the network of organs that help you to breathe.

4
00:00:36,130 --> 00:00:45,130
These systems help your body to absorb oxygen, the air, so your organs can work.

00:00:45,130 --> 00:00:57,210
Parts of the respiratory system

6
00:00:57,210 --> 00:01:07,219
Nostrils. The nostrils are in your nose. When we inhale, the air comes through our nostrils.

7
00:01:07,219 --> 00:01:18,219
Our nostrils are narrow and have some little air so it stops harmful elements.

8
00:01:18,219 --> 00:01:26,890
Trachea and bronchi. The trachea is a tube which filters the air that will

9
00:01:26,890 --> 00:01:33,930
inane. The trachea divide in two tubes that the end and connect with two lungs.

10
00:01:33,930 --> 00:01:39,810
Test two tubes that kill bronchi.

11
00:01:40,129 --> 00:01:47,950
The lungs and alveoli. The lungs are like big sacs in our chest. The lungs are filled with

12
00:01:47,950 --> 00:01:57,230
the alveoli. In the alveoli is where the exchange of oxygen is surrounded by capillaries. The air

13
00:01:57,230 --> 00:02:08,590
goes into the alveoli and the oxygen goes into the blood. Thanks for listening!
