The respiratory system helps us to breathe [take in and give out air]

provide oxygen to various part of our body .

It is made up of various organs .

Main Parts of the Respiratory System:

1. Nose/Mouth: Air enters through our nose or mouth. The nose has tiny hairs that filter dust and germs.

2. Trachea (Windpipe): This is a tube that carries air to the lungs.

3. Lungs: The main organs where oxygen is taken in and carbon dioxide is removed. We have two lungs, one on each side of our chest.

4. Diaphragm: A muscle below the lungs that helps us breathe in and out. When we breathe in, it moves down; when we breathe out, it moves up

   How it works

   
   

   1. Inhaling: When we breathe in, the diaphragm contracts and moves down. This creates more space in the chest, and air rushes into the lungs.

   2. Exhaling: When we breathe out, the diaphragm relaxes and moves up, pushing air out of the lungs..

      
      

   You breathe about 20 times a minute when you're resting!

   The average person breathes in about 11,000 liters of air each day!
