Abstract:
This article focuses on tracheal submucosal glands and their role in health and disease. The occurrence, distribution and morphology of tracheobronchial glands differ among vertebrate - and even mammalian - species. Tracheal glands are of major importance in physiology but also in pathological conditions such as tracheobronchitis, acute and chronic lung injury, cystic fibrosis and others. Some species do not possess tracheal glands; tracheobronchial clearance is performed by other secretory units.

Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...
The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
