Respiratory System

This week in the purple room was all about our respiratory system.
Our friends learned all about how we breath and where the air that we breathe goes.
Our bodies breathe either through our mouth or our nose. Our nose has tiny hair inside that cleans the air from dirt. After we take a breathe the air travels to our air tube called the trachea. The trachea is covered by the epiglottis and every time we breathe it opens up to let the air in. The epiglottis protects our respiratory system from food that we eat because our trachea is behind our esophagus. Ones the air is in the trachea it travels to our lungs where the air is cleaned and spread all over our body. We also learned about the function of our diaphragm. It’s located at the bottom of our lungs and every time we breathe in, the diaphragm goes down and give the lungs more room to expand, and every time we breathe out, the diaphragm comes up to help our lungs get rid of the air it’s not using.
We made our own lungs using balloons and straws to see what happens to our lungs when we breathe in and out.  Please check out our documentation board that documents all of the learning that has taken place over the past month as we learned about the human body.

Questions to ask at home.
Why does the epiglottis need to close our trachea?
Where is the trachea located?
How many lungs do we have?
What does the diaphragm do when we breathe in?
What do the little hairs in our noses do?
