1. RESPIRITORY SYSTEM

2. This is the system that consists of very important organs that allows us to breathe. It is responsible for the gas exchange as we breathe in oxygen and breathe out carbon dioxide

3. The main organs are:

4. Nasal cavity Pharynx\ larynx Trachea

5. Nasal cavity Look how big the tongue is!!!

6. The nasal cavity is the beginning of the respiratory system. Here, oxygen is breathed in through your nose or mouth and carried through and passed on to the next organ which is the pharynx.

7. Pharynx

8. Pharynx is just a fancy word for throat. The air is taken from the throat and passed on to the larynx.

9. larynx

10. Larynx is also just a fancy word for voice box. From your voice box the oxygen is carried to what looks like a long pipe called your trachea.

11. Trachea

12. The trachea is like a long pipe made up from small rings made out of very soft bone called cartilage. The trachea goes all the way down through your chest and breaks into two bronchi.

13. Bronchi

14. The bronchi are the pipes that pass on the air from the trachea to the bronchioles which are even smaller pipes.

15. Bronchioles

16. These pipes carry the oxygen into little sacks where all the magic happens, these sacks are called alveoli sacks.

17. alveoli

19. The alveoli are responsible for the gas change, they change oxygen into carbon dioxide. Then after the gas exchange, the process is reversed

20. Lungs

21. The lungs are divided into lobes, the right lung is bigger than the left because the left lung has a 2 lobes due to the bump to make a safe space for your heart, where as the right lung has 3 lobes. The lungs act in a sponge like way to absorb the carbon dioxide after the alveoli has released it. They also protect the bronchi and bronchioles from any harm.

22. Some diseases that attack and harm this system: bacterial pneumonia

23. Pulmonary embolism Blood clots and floods your lungs.

24. Lung cancer

25. If you want you lungs to stay healthy and to look like these…

26. Don’t smoke or inhale anything that you shouldn’t be inhaling. During the winter take multi vitamins so that you don’t get influenza and risk pneumonia.
