Digestive system, including the two parts of the digestive tract (mouth, pharynx, esophagus, stomach, small intestine, large intestine and anus) and digestive gland (salivary glands, gastric, intestinal glands, pancreas and liver). Digestive tract by the mucosa and smooth muscle. Digestive wall muscle contraction and relaxation, and the formation of digestive tract motility, and forward to eat the food, one by one, the digestive organs, digestion and absorption, the remaining food residues into the stool from anus discharge . Digestive gland to secrete a variety of digestive juice digestive juice contains digestive enzymes, can promote the digestion of food decomposition, in order to facilitate the absorption of nutrients. Visible, digestive function is receiving digest food, absorb nutrients. To ensure the growth and activities of the body's needs, and excreted in the residue. Obviously, the digestive system is related to human life and health systems. TCM summed up this system into the "stomach" called "the day after tomorrow".
The human digestive system developed earlier. About four weeks of the embryo when the stomach has occurred. The intestinal tract has been formed, the liver and pancreas has been taking shape, when the embryo 12 weeks, basically more complete, and gastrointestinal glands already have to 16 weeks. After birth, the digestive system will need to bear the digestion and absorption of the task, the newborn baby's natural sucking instinct, born six months after the love to chew, to full 1 year old on the digestion of a variety of oils and fats to a child when the digestion absorptive capacity of puberty, the digestive system development faster, increasing the capacity of the gastrointestinal, general stomach of young people can accommodate up to one ton l food, the digestive gland secretion of digestive juices is more and more to meet human growth and development needs of the nutrients a growing need.
