• The trachea, also called the windpipe, is a 4-inch-long tube with a diameter of less than an inch in most people.
• The trachea runs from the back of the larynx (voice box) to the back of the breastbone (sternum).
• Following that, the trachea separates into two bronchi tubes, one for each lung.
• The trachea is made up of about 20 strong cartilage rings. The back of each ring is made up of muscle and connective tissue.
• The mucosa that lines the trachea's interior is a moist, smooth tissue.
• The trachea extends and lengthens somewhat with each breath in before reverting to its regular size.
