endotrachea
Endotrachea refers to the space within the trachea, also known as the windpipe. The trachea is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing for the passage of air. The endotracheal space is the lumen, or the inner cavity, through which respiration occurs. Maintaining a clear endotracheal pathway is vital for breathing. Obstructions in this space, such as from foreign objects, swelling, or secretions, can lead to respiratory distress or failure. Medical interventions like endotracheal intubation are used to secure and maintain an open airway within the endotracheal space when a person is unable to breathe adequately on their own. This procedure involves inserting a tube into the trachea to bypass any blockages and facilitate ventilation. The integrity and patency of the endotracheal space are therefore critical for the exchange of gases necessary for life. Inflammation or infection of the trachea, known as tracheitis, can directly affect the endotracheal space, potentially narrowing it and impairing airflow.
