TracheaPlenumManifoldThe trachea is the airway in the respiratory system sometimes called the windpipe.
Air enters through your nose or mouth to your air sacs.
Goblet cells in the epithelium produce mucus that traps the dust and dirt that is taken into the windpipe through the mouth and nose. The long, finger-like cillia cells then sweep the mucus back up the windpipe to the throat where it can be swallowed and then destroyed in the stomach by the digestive juices and acids.

It next passes into the lungs when we breathe in, and out through the trachea, the larynx and the mouth and nose when we breathe out.

To allow the air to enter the body. The air can enter through either the nose or through the mouth.
The air enters through the mouth or the nose and is pulled down through the windpipe into the lungs. From the lungs, the oxygen molecules are dissolved in the alveoli and enter the red blood cells in the capillaries of the lung. From the capillaries, they travel to the heart and push oxygen through the body.

The mouth is the common opening for the food pipe and windpipe.
Once you push food to the back of your through to swallow it, the esophagus pushes it down to your stomach. As food goes from your mouth to your esophagus, it passes over top of the epiglottis, which shuts like a lid to keep stuff from falling down your trachea (windpipe).
The air that is inhaled passes through the throat. More specifically, it passes through the trachea on its way to the lungs.
The windpipe is also known as the trachea. The function of the windpipe is to provide a clear path for air from the nose and mouth to pass to and from the bronchial tubes.
