Which of the following processes primarily occurs in the mammalian oral cavity as described in the text?

  • A: Extensive chemical digestion of proteins.
  • B: Mechanical breakdown of food and initiation of saliva release.
  • C: Absorption of significant amounts of nutrients.
  • D: Storage of food for later digestion.

Explanation

The text states, 'Teeth with specialized shapes cut, mash, and grind, breaking the food into smaller pieces. This mechanical breakdown... Meanwhile, the anticipation or arrival of food in the oral cavity triggers the release of saliva by the salivary glands.' This explicitly describes mechanical breakdown and the initiation of saliva release.
