The main functions of the lesser curvature of the stomach are to store, grind and stir food and transport it to the duodenum; to participate in the maturation process of red blood cells, to secrete gastric acid and gastrointestinal digestive enzymes and other parts of digested food, and its specific roles are as follows: 1. After gastric peristalsis, food can be ground, stirred and transported to the small intestine. 2. The wall cells of the lesser curvature of the stomach can secrete endogenous factors to promote the absorption of vitamin B₁₂ and participate in the maturation of erythrocytes to prevent anemia. 3. Secretion of hydrochloric acid provides a suitable environment for pepsin, which plays the role of sterilization and bacteriostasis, and secretion of protease partially digests food. The lesser curvature of the stomach is concave to the upper right, with a total length of 12-14cm, which is the most common site of gastric ulcer and gastric cancer, so if you have epigastric pain, distension, nausea and vomiting and other discomforts, please go to the regular hospital in time to consult the doctor, and don’t be negligent in order to avoid delaying your condition.
