Study Notes

Digestive System

  • The digestive system is lined with simple columnar epithelial tissue.

Oral Cavity

  • Complete digestion occurs in the small intestine, but the process begins in the oral cavity.
  • The uvula is located in the oral cavity and its function is to help in the formation of sounds during speech.
  • The lingual tonsils are located on the back of the tongue in the oral cavity.
  • The tonsils in the oral cavity function as part of the immune system, helping to filter out pathogens.
  • The soft palate in the oral cavity separates the nasal cavity from the oral cavity and helps in the formation of sounds during speech.
  • The lingual frenulum is located in the oral cavity and its function is to connect the tongue to the floor of the mouth, limiting the tongue's movement.
  • The palatine tonsils are located on both sides of the back of the throat in the oral cavity.
  • The lateral walls of the oral cavity are formed by the cheeks.
  • The oral cavity contains the teeth.

Lower GI Tract

  • The main function of the lower GI tract is to absorb water and electrolytes.
