carbohydrates, proteins, and fats are transformed by chemical digestion into smaller molecules
that can be absorbed and used by cells.
What is deglutition? - CORRECT ANSWER - swallowing food particles from the mouth
into the pharynx and then to esophagus.
What is peristalsis? - CORRECT ANSWER - The movements that propel the food
particles through the digestive tract.
What is absorption? - CORRECT ANSWER - The simple molecules that are produced

What is the purpose of the incisors? - CORRECT ANSWER - Are chisel shaped and have
SHARP edges for biting food.
What is the purpose of the cuspids? - CORRECT ANSWER - Are cone shaped and have
points for grasping and tearing food.
What is the purpose of the bicuspids? - CORRECT ANSWER - They have flat surfaces
with rounded projections for crushing and grinding also known as premolars.
