Respiratory System (It’s a Gas!)

Our lesson is all about the respiratory system.

So what have I learned? Here they are…

• The respiratory system is consists of 2 lungs, upper and lower airways, terminal air sacs (alveoli), a thoracic cage and muscles of breathing

• There are two processes of breathing: ventilation and respiration.

• The upper airways of the respiratory tract are in charge for initially conditioning the inhaled air.

• The lower respiratory tract? Hmm... I can’t recall anything about it...

• The diaphragm is the main muscle of breathing.

Ok… I guess that’s all I can remember right now.

Well… teaching suggestions? Illustrations will be very helpful especially in discussing about the process of breathing itself 
