Parts Of The System

The Five Parts :

1 - The Diaphragm - A muscle that pushes the lung up and down letting you breathe.

2 - The Trachea - Your wind pipe that air travels in and out of when you breathe.

3 - The Alveolus(s) - The first picture, sacs the absorb o2 and transfer it to your blood.

4 - The Epiglottis - A flap in your Trachea that lets air in and keeps solid and liquid out!

5 - Mucus - Yes "buggers", they trap invaders and dirt to make sure your lungs stay safe.
