Trachea: The trachea

The trachea , commonly known as the windpipe, is a cylindrical tube that serves as a vital part of the respiratory system. It is approximately 10-12 centimeters in length and 2-2.5 centimeters in diameter in adults. The trachea is made of cartilage rings, smooth muscle, and connective tissue, which help maintain its structure and keep the airway open for the passage of air. The trachea , bronchi and bronchioles form the tracheobronchial tree – a system of airways that allow passage of air into the lungs, where gas exchange occurs. These airways are located in the neck and thorax. In this article we will look at the anatomical position, structure and neurovascular supply of the airways; as well as considering their clinical relevance. Learn about the trachea , the long tube that connects your voice box to your lungs. Find out how it works, what can affect it and how to keep it healthy.
