Trachea (Medical Definition) | Quick Explainer Video

The trachea, also known as the windpipe, is a vital part of the respiratory system that connects the larynx (voice box) to the bronchi in the lungs. It is made up of cartilage rings that provide support and prevent collapse, allowing air to flow in and out of the lungs. The trachea also contains cilia, tiny hair-like structures that help to trap and remove foreign particles and mucus from the respiratory tract. Any blockage or damage to the trachea can lead to breathing difficulties and other serious health issues.
