Lungs- help oxygen from the air we breathe enter the red blood cells in the blood. It also help the body to get rid of Carbon Dioxide when we breathe out.
Trachea- connects the larynx to the bronchi of the lungs.
Bronchi- carry air from the trachea into the lungs.
Diaphragm- separates the chest cavity from the abdomen.
For my project, I did an interactive model of the Respiratory System. First, I cut a circular hole at the bottom of a large plastic jar. Next, I made the lungs, trachea, and bronchi by using straws, ballons, paint, and rubber bands.
Then, I put the trachea through the hole I made at the bottom of the jar and put clay to put it in place. Lastly, I replaced the lid with a ballon to represent the diaphragm.
