The trachea is located in the human neck and chest area, serving as a vital part of the respiratory system. It is often referred to as the windpipe and connects the larynx (voice box) to the bronchi, which lead into the lungs. The trachea is composed of cartilage rings that keep it open, allowing for the passage of air during breathing. Its primary function is to transport air to and from the lungs, where gas exchange occurs. The trachea also has a lining that helps to trap dust and foreign particles, protecting the lungs from potential irritants and infections.
