Trachea

The trachea, commonly known as the windpipe, is a tube that connects the throat (larynx) to the lungs. It serves as the main airway that allows air to flow in and out during breathing. The trachea is supported by cartilage rings that keep it open and flexible, enabling it to adjust during breathing, speaking, and swallowing. It also contains mucous membranes and tiny hair-like structures called cilia that help trap and remove dust, germs, and mucus, keeping the lungs healthy. Overall, the trachea plays a crucial role in respiratory function by providing a clear path for airflow.
