- There are three parts of stomach named as cardia, body and pylorus.
- Pylorus has two regions. Pylorus opens into small intestine through the pyloric orifice.
- Stomach is the food reservoir and it digests food only chemically with the help of enzymes.
- Pyloric sphincter is located in the pyloric orifice. It is made up of a thick band of circular muscles.
- oblique muscles
- gastric glands
- Oblique muscle
- Gastric gland
- Foveolar layer mucus
- Parietal cell secretion blocked: Proteins are not hydrolyzed and decrease in RBC population
- Congenital absence of enterokinase: Carbohydrate digestion
- Cholecystectomy: Difficulty in digestion of fat-rich food
- Goblet cells non-functional: Smooth movement down the intestine affected
