Respiratory system

Function: The Respiratory system provides oxygen and takes away waste witch is carbon dioxide.

Organs: Lungs: have bronchioles
             Bronchioles: have alveoli
             Alveoli: Oxygen passes from the alveoli into capillaryes of the circulatory system.
             Diaphragm: Pulls and pushes the air
             Trachea: Oxygen tube          

We made a model of the Respiratory system and we used plastic bottles and balloons. We made it by putting the regular balloon and not the ripped one on the top and the ripped one on the bottom because there was a hole on the bottom of the bottle and the way it works is by pulling the bottom. Then the regular balloon gets air and then releases the air like we do.
