The trachea is lined by pseudostratified squamous epithelium. Epithelium lines body cavities and surfaces. Pseudostratified squamous epithelium is pseudostratified because it is only one cell layer thick, yet it appears to be stratified. In reality, every cell touches the basement membrane.
The histological structure of the epithelium and the underlying connective tissue of the bronchi corresponds largely to that of the trachea and the main bronchi. In addition, bronchi are surrounded by a layer of smooth muscle, which is located between the cartilage and epithelium.n addition to the staple of basal cells, ciliated cells and goblet cells, the respiratory epithelium also contains brush cells, endocrine cells (or small granule cells, function not clear) , surfactant-producing cells (or Clara cells) , and serous cells. Epithelium and underlying lamina propria are called the mucosa.
