What Are Bronchial Tubes?

Bronchial Tubes

Say: BRONG-kee-ul toobz

When a person breathes, air comes in through the nose or mouth and then goes into the trachea (windpipe). From there, it passes through the bronchial tubes, which are in the lungs. These tubes, or airways, let air in and out of your lungs, so you can breathe. You can call them by their nickname: bronchi (say: BRONG-kye). The bronchial tubes branch into smaller tubes called bronchioles (say: BRONG-kee-ohlz).
