TRACHEAS Meaning and
Definition
-
The trachea, also known as the windpipe, is a tube-like structure in the respiratory system that connects the larynx (voice box) to the bronchi of the lungs. It serves as the main passage for air to flow in and out of the lungs during breathing.
A typical trachea is composed of rings of cartilage that provide structural support and prevent collapse while allowing flexibility. These cartilaginous rings run along its length and give the trachea a cylindrical shape. The inner lining of the trachea contains ciliated epithelial cells that possess hair-like structures called cilia, which help in moving mucus and foreign particles upward towards the throat for elimination.
The trachea is responsible for conducting air and facilitating the exchange of oxygen and carbon dioxide between the atmosphere and the lungs. It filters, warms, and humidifies the inhaled air, ensuring that it reaches the lungs in optimal conditions for gas exchange.
In medical terms, the trachea can occasionally be affected by various conditions or diseases, such as tracheitis (inflammation of the trachea), tracheal stenosis (narrowing of the trachea), or tracheal tumors. Treatment for tracheal disorders may involve medications, therapies, or in some cases, surgical interventions to restore its normal function and maintain proper airflow.
