Continued peristalsis in the stomach grinds and mixes the food thoroughly, mixing in digestive chemicals and enzymes. This produces a mass called chyme . Next, the chyme is passed through the pyloric valve into the small intestine. More digestive enzymes are added, and during the trip to the large intestines, digestion and absorption are nearly completed. The large intestine holds the waste material for elimination at a suitable time.
Transit time varies.
The time from eating to elimination can take from one to three days. 84 Several organs secrete enzymes or fluids needed for digestion. Stomach - Water, Hydrochloric acid, proteolytic enzymes . Absorption and transportation of nutrients 89 nutrient absorption Cells of the intestinal lining absorb nutrients from the digested food-stuff passing through and release them into the blood and lymph. The cells of the intestines have villi which are covered with microvilli on the food mass side, and capillaries and lymph vessels on the other side of the cell.
