    Amylase's Function

    Amylase breaks down starch into maltose, a simpler sugar.

    Teeth Types

    Incisors cut, canines tear, premolars grind, and molars chew food.

    Stomach Protection

    The stomach has a mucus layer to protect it from its own acid.

    Small Intestine Absorption

    The small intestine's villi increase surface area to absorb nutrients.

    Study Notes

    Digestive System

    • Saliva is produced in salivary glands
    • Amylase breaks down starch into sugars (maltose)
    • 32 teeth in an adult mouth:
      • Incisors: sharp, cut food
      • Canines: pointed, tear food
      • Premolars: flat, grind food
      • Molars: grind & chew food
    • Stomach:
      • Lined with mucus to prevent acid damage
      • Contains hydrochloric acid and protein-digesting enzymes
      • Churns food (physical digestion)
      • Acid helps digestion
    • Small Intestine:
      • Contains villi (tiny finger-like structures)
      • Large surface area for absorption
      • Aids absorption of nutrients
