Digestive system

Function: interface between body and environment, digestion: food is broken down physically and chemically so that the degraded products can be absorbed into the body.

Alimentary mucosa:

  1. Barrier function: The mucosa serves as a barrier to the noxious substances, antigens, and pathogenic organisms.
  2. Immunologic function: Lymphatic tissue in the mucosa serves as a first line of defense of the body by the immune system.
  3. Secretory function: The lining of the alimentary canal secretes, at specific sites, digestive enzymes, hydrochloric acid, mucin, and antibodies.
  4. Absorptive function: The epithelium of the mucosa absorbs metabolic substrates, i.e., the breakdown products of digestion, vitamins, water, electrolytes, recyclable materials such as bile components and cholesterol and other substances.
