Your trachea, or windpipe, is one part of your airway system. Airways are pipes that carry oxygen-rich air to your lungs. They also carry carbon dioxide, a waste gas, out of your lungs. When you inhale, air travels from your nose, through your larynx, and down your windpipe. The windpipe splits into two bronchi that enter your lungs. Problems with the trachea include narrowing, inflammation, and some inherited conditions. You may need a procedure called a tracheostomy to help you breathe if you have swallowing problems, or have conditions that affect coughing or block your airways.
Trachea is also known as the windpipe. It is a tube about 10-12.5 cm long (4-5 inches) and about 2.5 cm wide (1 inch). The trachea extends from the lower edge of the larynx downward into the thoracic cavity, where it splits into right and left bronchi. Rings of cartilage keep the airway open. Functions of the trachea: 1  to conduct air to and from the lungs; 2  to filter air;  to trap particles in mucus.
