The trachea (: tracheae or tracheas), also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all land vertebrate animals' lungs. The trachea extends from the larynx and branches into the two primary bronchi. At the top of the trachea, the cricoid cartilage attaches it to the larynx. The trachea is formed by a number of horseshoe-shaped rings, joined together vertically by overlying ligaments, and by the trachealis muscle at their ends. The epiglottis closes the opening to the larynx duri

AI overview

The trachea, or windpipe, is a tube made of cartilage that connects your voice box to your lungs and allows air to pass through to them. It's a crucial part of the breathing system found in nearly all land vertebrates, and it's held together by ring-shaped cartilage and muscles that keep it open for air passage.
