    The stomach is located just below the diaphragm and has a distinctive J-shape. The stomach is comprised of the fundus (upper region), the body (central region), the antrum (lower area), and the pylorus (sphincter at the lower end). The stomach acts as a temporary storage for food as the digestive process continues. Peristalsis churns and mixes the food with highly acidic gastric juices and transforms the food into chyme. Chyme is gradually released into the small intestine through the pyloric sphincter at about 3mL per 20 seconds. Gastric emptying into the duodenum takes 40 minutes to 2 hours (“Biology of the digestive tract”, 2024).
