Question

Nonkeratinized stratified squamous epithelium can be found lining what area of the respiratory tract? alveoli nasal cavity bronchioles trachea oropharynx

Answer 1

Oropharynx

Step-by-step explanation:

Oropharynx communicates with the mouth through the isthmus of the throat. It is a small space in the oral cavity between the root of the tongue, the soft palate and the epiglottis. It is the only portion of the oral cavity corresponding to a real cavity. The epithelial laryngeal lining is characterized by a non-keratinized stratified squamous epithelium.

Answer 2

The answer is oropharynx. The reason for this type of epithelium in this region of the respiratory tract is due to its proximity to the esophagus. This means that this region of the respiratory tract is subject to abrasion by food passing down the esophagus. This epithelium is continuous with that of the esophagus.
