The Gastrointestinal Tract

  • Franz Hartmann
  • Harro Jenss


With its mucosal surface thought to be 200 times the body surface area, the gastrointestinal tract is a major route of exposure to pathogenic organisms and environmental chemicals. Food- and water-borne chemicals enter the body via the gastrointestinal tract. Most agents are ingested; however, some inhaled substances are swallowed after being trapped in the mucus of the respiratory tract. Thus, apart from its classic role of nutrient absorption, the gastrointestinal tract must also protect the body from environmental assault (83, 89, 109, 137, 166).
