Your bronchial tubes are one of the tubes where air passes through your lungs to get to the area where oxygen enters the bloodstream and waste products are released so they can be breathed out of the body. When you breathe air in, it passes through your nose or mouth, through the larynx, and into the trachea or windpipe.
From your trachea, air splits off into your right and left main bronchial tubes, or right and left main bronchus. As your bronchial tubes continue to branch off and get smaller and smaller, they are referred to as bronchi and then bronchioles. Your airways terminate at the air sacs called alveoli , where the exchange of carbon dioxide and oxygen takes place. The alveoli are surrounded by a network of blood vessels called capillaries.
The capillaries are where oxygen enters the bloodstream to be delivered to the rest of the body and the body gets rid of some waste products such as carbon dioxide. After the oxygen enters the bloodstream in the capillaries, it travels back to the heart where it is distributed to the rest of the body. As oxygen is delivered to cells in the body it is exchanged for carbon dioxide that is then delivered back to the capillaries and ultimately exhaled out of the lungs.
While your healthcare provider probably often talks about the overproduction of mucus in asthma, you need some mucus to be healthy. The mucus acts as a sticky pad and tries to keep foreign things that should not be in your lungs out. Not only does the mucus keep the lungs moist, but it acts as a trap keeping out things like dust, bacteria, or viruses that could trigger an asthma attack.

The upper respiratory tract upper airway consists of the nose, mouth, sinuses, pharynx upper section of the throat , and larynx voice box. The lower respiratory tract consists of the trachea windpipe , bronchial tubes, and lungs. The bronchial tubes carry air into the lungs and branch into smaller and smaller bronchioles.
These end in alveoli air sacs. The main function of the respiratory system is to supply the blood with oxygen so the blood can deliver oxygen to all parts of the body.
