The trachea, or windpipe, plays a crucial role in maintaining respiratory health by providing a clear airway for the passage of air to and from the lungs. It is lined with cilia and mucus that trap and expel foreign particles and pathogens, helping to prevent infections and maintain clean air within the respiratory system. Additionally, the trachea helps regulate airflow and supports the lungs during breathing, ensuring efficient gas exchange and overall respiratory function.
