1. What are the four parts of the stomach?
Four parts of the stomach: Cardia, fundus, body, antrum.
2. Describe the location and function of the cardia.
Location and function of the cardia: Near gastroesophageal junction, prevents reflux.
3. What is the function of the fundus of the stomach?
Function of the fundus: Food storage and initial digestion.
4. Identify the area of the stomach responsible for grinding and mixing food with gastric juices.
Area responsible for grinding food: Antrum.
5. Describe the structure and function of the body of the stomach.
Structure and function of the body: Main region for food storage and mixing.
6. What is the role of the antrum in gastric function?
Role of antrum: Grinding food and regulating gastric emptying.
7. Explain the significance of the pylorus in gastric emptying.
Significance of pylorus: Controls passage of chyme into duodenum.
8. Describe the structure and function of the pyloric sphincter.
Structure and function of pyloric sphincter: Regulates chyme flow.
9. What is the histological composition of the mucosa of the stomach?
Histological composition of stomach mucosa: Mucous membrane with gastric pits and glands.
10. Explain the role of gastric pits in gastric secretion.
Role of gastric pits: Site of gastric juice secretion.
11. What are gastric glands, and what do they secrete?
Gastric glands: Tubular structures secreting gastric juice.
12. Describe the structure and function of chief cells in the stomach.
Structure and function of chief cells: Secrete pepsinogen for protein digestion.
13. What is the function of parietal cells in gastric secretion?
Function of parietal cells: Secrete HCl and intrinsic factor.
14. Explain the importance of intrinsic factor secreted by parietal cells.
Importance of intrinsic factor: Necessary for B12 absorption.
15. What is the role of mucous cells in the stomach?
Role of mucous cells: Produce mucus for protection.
16. Describe the function of G cells in gastric secretion.
Function of G cells: Produce gastrin to stimulate acid secretion.
