Question

The function of the vibrissae in the vestibule is to:

a. provide a large, mucus-covered surface area over which air must pass before reaching the pharynx.
b. provide an initial "filter" to screen particulate matter from air that is entering the system.
c. produce copious quantities of mucus.
d. serve as resonating chambers for speech.

Answer 1

A correct answer is an option - B. provides an initial "filter" to screen particulate matter from the air that is entering the system.

Step-by-step explanation:

The vestibule is the most anterior region of the nasal cavity lined with epithelium skin and surrounded by the cartilage with the small hair present in it. These nasal hairs are known as vibrissae.

Vibrissae are present on the nasal cavity opening and play the role of filters as they trap dust and particle from the air inhaled by the respiratory system.

Thus, the correct answer is option B.
