First, the function of the stomach:
The main function of the stomach is to store and digest food. When food enters the stomach, the stomach muscles will undergo mechanical digestion through contraction and relaxation. At the same time, gastric acid and digestive enzymes in gastric juice will be mixed with food, and protein, fat and other nutrients in food will be decomposed, which will provide a basis for further absorption by small intestine.
Second, the shape and structure of the stomach:
The shape and structure of the stomach vary from person to person, but it usually presents a curved tubular structure. The stomach consists of four parts: cardia, fundus, stomach body and pylorus. The cardia is the entrance of the stomach and connected with the esophagus; The fundus of the stomach is a part of the stomach and contains most of the gastric juice. The stomach body is the main part of the stomach, responsible for the digestion and absorption of food; The pylorus is the outlet of the stomach and connects with the small intestine.
Third, stomach trouble:
Gastropathy is one of the common diseases in digestive system, including gastritis, gastric ulcer and gastric cancer. Gastritis refers to inflammation of gastric mucosa, usually caused by Helicobacter pylori infection, and its symptoms include abdominal pain, bloating and nausea. Gastric ulcer means that the depth of gastric mucosal injury exceeds the muscularis mucosa, and the symptoms include periodic abdominal pain, acid regurgitation and belching.
Fourth, the maintenance of the stomach:
Developing the good habit of chewing slowly can increase the secretion of saliva and help food to digest and absorb better. If you don't chew it carefully, the rough bookstore will directly wear the gastric mucosa, increase the burden on the stomach, and prolong the residence time of food in the stomach, thus causing muscle fatigue and decreased gastric motility.
Supplementing probiotics every day is good for your health. Probiotics can regulate intestinal flora, improve gastrointestinal function, colonize live bacterial strains to the digestive system, protect the gastrointestinal tract, give full play to the role of beneficial bacteria, balance gastrointestinal flora, repair gastrointestinal mucosal damage, maintain gastrointestinal health, and achieve the purpose of real gastrointestinal health care and conditioning.
Verb (abbreviation of verb) summary:
The stomach is an important part of the human digestive system and plays an important role in the digestion and absorption of food. Understanding the functional morphology and structure of the stomach, common diseases and maintenance methods will help us to better protect our health.
