No absorption of food or of end products of digestion is known to occur inthe mouth and esophagus. Certain drugs, however, may be absorbed fromtheir epithelial surfaces.Absorption from the stomach of the monogastric animal is very limited un-der normal conditions. On the whole, food substances are degraded to absorba-ble units only to a limited extent in the stomach. Proteins are only partially de-graded, fats are hydrolyzed only to a slight extent, and carbohydrate digestionis far from complete. Although water can be absorbed from stomach pouches,it is doubtful that under ordinary circumstances water remains in the stomachlong enough to undergo any significant reduction in volume. Inorganic salts arenot absorbed in significant amounts, but certain drugs such as ethanol are ab-sorbed from the monogastric stomach. There is a continuous flux of water andwater-soluble substances across the water-permeable pores of the gastric muco-sa, but normally their net rate of absorption from the lumen is small.The small intestine is the chief site of absorption in carnivores and omni-vores. It is also of great importance in herbivores. Vitamins, minerals, andend products of digestion are absorbed largely from the proximal half; vitaminB12, bile acids from bile, and water are absorbed largely in the distal portion.The large intestine as an organ of absorption is of limited importance incarnivores and humans except in the initial part of the colon, where water andelectrolyte absorption occurs.
