The stomach is anatomically divided into four parts, the cardia, fundus, body and pylorus.
The cardia, which is connected to the esophagus, is the beginning part of the stomach. The area near the cardia is called the cardia portion, which prevents the reflux of food, gastric acid, and other substances from the stomach into the esophagus.
Above the level of the cardia, the part that expands to the upper left is called the fundus of the stomach, which can also be called the gastric fornix clinically, and can contain the air that enters the stomach when swallowing food; the part from the fundus of the stomach down to the angular incision is called the body of the stomach, which is larger in size and can hold food.
The pyloric portion is mainly the part between the lower border of the gastric body and the pylorus, which is connected to the duodenum and prevents intestinal contents from refluxing into the stomach and causing damage to the gastric mucosa. The Helicobacter pylori bacteria are easily parasitized in the pylorus, therefore, this is a good place for gastric ulcer, gastric cancer and other diseases.
If the patient has stomach discomfort, it is recommended to consult a doctor in time and receive treatment actively, so as not to delay the condition.
