Windpipe

Windpipe (also known as the trachea) is a tube that connects the pharynx and larynx to the lungs, allowing the passage of air. It is an essential part of the respiratory system in humans and many other animals.

Anatomy

The windpipe is located in the neck and chest area, extending from the larynx to the bronchi. It is approximately 10 to 12 cm long and 2 cm in diameter. The trachea is surrounded by 16 to 20 C-shaped rings of cartilage that provide structure and prevent the trachea from collapsing.

Function

The primary function of the windpipe is to provide a clear airway for air to enter and exit the lungs. The mucus lining of the trachea traps dust and other particles, preventing them from entering the lungs. The cilia on the surface of the cells lining the trachea move this mucus and material out of the lungs.

Diseases and conditions

Several diseases and conditions can affect the windpipe, including tracheitis, tracheal stenosis, and tracheal cancer. Symptoms of these conditions can include difficulty breathing, coughing, and wheezing.

Treatment

Treatment for conditions affecting the windpipe depends on the specific condition and its severity. Treatments can include medication, surgery, or other procedures. For example, a tracheostomy is a surgical procedure that creates an opening in the neck for direct access to the trachea.
