Where is your bronchial tube

The next step is through the trachea, which carries the air to the left and right bronchus. The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles.

These passageways then evolve into tiny air sacs called alveoli , which is the site of oxygen and carbon dioxide exchange in the respiratory system. Primary bronchi are located in the upper portion of the lungs, with secondary bronchi near the center of the lungs.

Tertiary bronchi are located near the bottom of these organs, just above the bronchioles. No gas exchanges occur in any of the bronchi. When the bronchi become swollen due to irritants or infection, bronchitis results and makes breathing more difficult.

Bronchitis sufferers also tend to have much more mucus and phlegm than someone without inflamed bronchi. The trachea, or windpipe, helps supply air to the lungs by providing a passage way from the mouth.

It is about 4 to 5 inches long and 1 inch in…. The jejunum is one of three sections that make up the small intestine. Learn about its function and anatomy, as well as the conditions that can affect…. 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.

The respiratory system does this through breathing. Author: Healthwise Staff. Medical Review: E. This information does not replace the advice of a doctor. Healthwise, Incorporated, disclaims any warranty or liability for your use of this information. Select basic ads.

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.
