Respiratory system, made by Leo of Cuarto B.

2
00:00:28,660 --> 00:00:35,079
Respiratory system. What is the respiratory system and what is its functions?

3
00:00:35,799 --> 00:00:39,259
It's a network of organs held due to breath.

4
00:00:39,920 --> 00:00:44,979
Absorb oxygen from the air, cleanse your body from unwanted.

5
00:00:45,920 --> 00:00:49,079
What is the parts of the respiratory system?

6
00:00:49,079 --> 00:00:56,079
The parts of the respiratory system are nostrils, bronchi, lungs, trachea and alveoli.

7
00:01:05,469 --> 00:01:06,469
Nostrils

8
00:01:06,469 --> 00:01:09,469
The nostrils are in your nose.

9
00:01:09,469 --> 00:01:15,469
When we inhale, the air comes through our nostrils.

10
00:01:15,469 --> 00:01:24,469
Our nostrils are narrow and have some little air so it stops harmful elements.

11
00:01:42,120 --> 00:02:06,920
Trachea. The trachea is a tube which filters the air that we inhale, bronchi. The trachea divides into two tubes at the end and connects with the two lungs. These two tubes are tied, the bronchi.

12
00:02:06,920 --> 00:02:26,349
Lungs. The lungs are like big sacks in our chest.

13
00:02:26,349 --> 00:02:30,349
Alveoli. The lungs are filled with alveoli.

14
00:02:30,349 --> 00:02:39,349
In the alveoli is where the exchange of oxygen and carbon dioxide happens.

15
00:02:39,349 --> 00:02:44,349
The alveoli is surrounded by capillaries.

16
00:02:44,349 --> 00:02:51,349
The air goes into the alveoli and the oxygen goes into the blood.

17
00:02:51,349 --> 00:02:59,120
Thank you for listening!
