Parts of the respiratory system

Here are the main components of the respiratory system:


This is your main windpipe, which starts at the back of your throat.


You have two of these, a left and right one that split off from the trachea to feed each lung.


These tiny tubes branch off from the bronchi, extending throughout all of your lungs.


These are the tiny air sacs that connect to each bronchiole. Blood passes through here, exchanging fresh oxygen from the air for carbon dioxide to be carried back out and exhaled.


This is your primary breathing muscle, located at the base of your chest.

People who suffer from chronic lung disorders have something wrong with one or more parts of this system. This prevents their lungs from working properly, and as a result, prevents their body from getting the oxygen it needs to function properly.
