Analyze Question 17

Using the Medical Terminology knowledge point, we analyze the term "bifurcate." The prefix "bi-" means two, and "furca" means fork. Therefore, to bifurcate means to divide into two branches.

Analyze Question 18

Using the Upper Respiratory Tract knowledge point, we examine the vestibular region of the nasal cavity. The nasal vestibule is the anterior portion containing coarse hairs (vibrissae) that filter out large dust particles and pathogens, acting as a first line of defense.
