The respiratory system is a collection of organs and tissues that work together to enable you to breathe.
The trachea or the windpipe is a long, U-shaped tube that connect the larynx to the lungs. It functions to carry air in and out of your lungs.
Bronchioles are the lower part of the Bronchi. They function to allow air to pass inside the lungs, specifically to the network of alveoli in your lungs where oxygen and carbon dioxide exchange occurs.
Alveoli are small, balloon-shaped air sacs found at the end of the bronchioles. They allow the exchange of oxygen and carbon dioxide between the lungs and the blood during respiration. The oxygen inhaled passes through the alveoli and then into the blood while carbon dioxide is transferred from the blood to the alveoli then expelled after exhalation.
