C Correct answer
Explanation

It is chief function of buccal cavity to break down huge macromolecules (proteins, fats and starch), which cannot be absorbed intact, into smaller molecules (amino acids, fatty acids and glucose) that can be absorbed across the wall of the tube, and into the circulatory system for dissemination throughout the body.

Multiple choice
  1. Tip

  2. Middle

  3. Back

  4. All these

A Correct answer
Explanation

The tip of the tongue is densely packed with taste buds and nerve endings, making it the most sensitive part for detecting flavors and textures. The middle and back areas have different distributions of taste receptors.

Multiple choice
  1. Regulates the air pressure on both sides of the ear drum

  2. Regulates temperature on both sides of the ear drum

  3. Regulates the sound variation on both sides of the ear drum

  4. None of these

C Correct answer
Explanation

The ear serves two primary functions: hearing (audition) and maintaining equilibrium or balance, which is mediated by the vestibular system in the inner ear.

Multiple choice
  1. Protect ear from insects, germs and dust

  2. Help to maintain the temperature of the auditory canal

  3. Help to maintain the dampness of the auditory canal

  4. All of the above
