Explain why the oropharynx and laryngopharynx are lined with nonkeratinized stratified squamous epithelium rather than pseudostratified ciliated columnar epithelium
What will be an ideal response?
Nonkeratinized stratified squamous epithelium provides better protection than pseudostratified ciliated columnar epithelium since it contains many cell layers. Both the oropharynx and laryngopharynx serve as a passageway for both food and air. The multiple layers prevent abrasion from the passage of food.
