Mucous membranes of the upper respiratory tract help prevent the entry of pathogens because they have:
A)smooth muscle tissue
B)stratified squamous epithelial tissue
C)microvilli
D)ciliated epithelial tissue

Question

Quizplus · Accepted Answer

The ciliated epithelial tissue has tiny hair-like structures that help move mucus and trapped pathogens out of the respiratory tract, preventing their entry into the body. Smooth muscle tissue, stratified squamous epithelial tissue, and microvilli do not play a significant role in preventing the entry of pathogens.
