Gastric Absorption Function Coefficient:
The gastric gland in gastric mucosa secretes a kind of colorless and transparent acidic gastric juice, and the gastric gland of an adult can secrete 1.5-2.5 liters of gastric juice each day. Gastric juice contains three components play items, namely, pepsin, hydrochloric acid and mucus. The pepsin can decompose proteins in food into proteose and protease with smaller molecules. Hydrochloric acid is gastric acid. Gastric acid can change protease with no activity into active pepsin and create a suitable acidic environment for pepsin, having the function for killing bacteria entering into the stomach with food. Gastric acid can stimulate the secretion of pancreatic juice, bile and small intestinal fluid after entering into the small intestines.The the caused by the acidic environment of gastric acid can help the small intestines absorb iron and calcium. With the role of lubrication, gastric mucus can reduce the damage of food for gastric mucosa and can also reduce the erosion of gastric acid and pepsin for gastric mucosa, having a protective effect for stomach.
Small Intestine peristalsis Function Coefficient:
Small intestine peristalsis is in a unique movement style, being an alternating motion of rhythmic contraction and relaxation with circular muscle as the main.
Function: it promotes chyme and digestive juice to be fully mixed for chemical digestion; it makes chyme close to the intestine wall to promote absorption; it squeezes the intestine wall to promote reflux of blood and lymph.
