The respiratory system is made up of organs and tissues that help you breathe. The main parts of this system are the airways, the lungs and linked blood vessels, and the muscles that enable breathing.
The respiratory system takes in air starting from your nose and mouth, then sends it through a tube in your throat called the trachea, and then into your lungs. The trachea connects to the lungs by splitting into two tubes called bronchiole tubes, which eventually split into smaller and smaller tubes.
