Answer:
B) lines most of the respiratory tract
Explanation:
The respiratory epithelium refers to a type of ciliated columnar epithelium that is present in most of the respiratory tract. This epithelium has a diverse range of functions: from barrier/protective functions for the prevention of dangerous microorganisms to the production of moisture by secretion.
Pseudostratified respiratory epithelium consists primarily of columnar ciliated cells. Most of the respiratory passageways, from the nasal cavity through the bronchi, are lined by ciliated, pseudostratified columnar epithelium with goblet cells.
The respiratory epithelium that lines the upper respiratory tract is known as a ciliated pseudostratified columnar epithelium. The reason behind its name is the the arrangement of the numerous cell types that compose the respiratory epithelium.
