Hello little scientist! This is the Respiratory system. Let me show you around it and what happens
Up here is where it starts. The nose, mouth, and a part called the Nasal Cavity. When breathing in air passes through the Nasal Cavity and travels down the Epiglottis.
This tube isn't actually one tube. It consists of the epiglottis, larynx, trachea, and bronchus. They all work together to let air travel to the lungs.
Right there in the lungs gases or more known as oxygen and carbon dioxide are exchanged.
Now the process happens again but the opposite. Instead of breathing in oxygen you are breathing out carbon dioxide. You do the process again.
Well that's the bell. Thanks for reading.
