Knowledge of stomach and intestine
1, the function of the stomach, the main function of the stomach is to digest and absorb nutrients in food and excrete food residues at the same time. The digestive function of gastrointestinal tract involves the secretion and function of gastric acid, bile, digestive enzymes and other substances. These substances cooperate with each other to break down food into small molecules, which is convenient for human body to absorb and utilize.

The occurrence of these diseases is related to many factors such as diet, living habits and heredity. For example, unhealthy living habits such as irregular diet, overeating, smoking and drinking can easily lead to gastric mucosal damage, which in turn leads to gastritis, gastric ulcer and other diseases.
3, the stomach also has endocrine function, can secrete some hormones, such as gastrin, insulin and so on. These hormones are involved in regulating the physiological activities of the human body. In addition, genetic factors are also an important cause of gastrointestinal health problems. Some people are born with excessive gastric acid secretion or fragile gastric mucosa, and are prone to stomach problems.
