Key Points

  •  Mouth allows air and nutrients to enter your body, and it also helps you speak. It's also called the oral cavity.
  • The primary function of teeth is mastication, which involves the cutting, mixing, and grinding food to allow the tongue and oropharynx to shape it into a bolus that can be swallowed.
  •  Tongue moves food around your mouth to help you chew and swallow.
  • Salvia plants are traditionally noted for their antioxidant effects and ability to enhance 'head and brain' function, improve memory, quicken the senses, and delay age-associated cognitive decline
