    • The functions of the digestive system are:

    – To break down food to a form that can be used by body cells

    – The digestive process, which includes transporting food and wastes, physical and chemical breakdown, absorption of digested food, and final elimination of wastes

Disorders of the digestive system l.jpg

Disorders of the Digestive System

  • Alactasia

    • Also called “lactose intolerance.” Not enough of the enzyme lactase is produced. The unabsorbed lactose ferments in the intestines leading to gas, cramps, and diarrhea.

  • Appendicitis

    • Inflammation of the appendix

  • Cholecystitis

    • Inflammation of the gallbladder

Disorders of the Digestive System (continued)

  • Cirrhosis

    • A chronic degenerative condition of the liver accompanied by the formation of scar tissue

  • Colon cancer

    • An abnormal growth in the large intestine

  • Constipation

    • The inability to defecate

  • Crohn’s disease

    • Inflammation and ulceration, usually affecting the ileum and colon, or both

Disorders of the digestive system continued8 l.jpg

Disorders of the Digestive System (continued)

  • Diarrhea

    • The passage of frequent and watery stools

  • Diverticulitis

    • The weakening of the colon wall, leading to formation of a pouch causing infection or abscesses if fecal material trapped

  • Food poisoning

    • Illnesses transmitted by food
