(anatomy) the membranous tube in the body that carries air from the throat to the bronchi
The trachea, commonly referred to as the windpipe, is a vital respiratory structure in the human body. It is a flexible tube that connects the larynx to the bronchi, allowing air to pass in and out of the lungs. The trachea is composed of rings of cartilage, which provide support and prevent collapse during breathing. It is lined with a layer of specialized cells that produce mucus, helping to trap dust, pathogens, and other foreign particles, and it is equipped with cilia that move in a coordinated manner to propel the mucus upward. The trachea plays a crucial role in the respiratory system, ensuring the proper flow of air into and out of the lungs.
