NUTRITION: RESPIRATORY SYSTEM

 Our body needs oxygen to work. We use the respiratory system to breathe (get oxygen from the air) and move oxygen through our bodies.

There are 3 parts:

- We breathe air in through our NOSE, we breathe automatically.

- The air goes down the TRACHEA (or windpipe)

- The air goes into the LUNGS, where the oxygen passes into the blood.
