Opening at the lower end of the stomach is called what?

Explanation:
Opening at the lower end of the stomach is the pyloric orifice. This is the distal entrance from the stomach into the duodenum, located at the pylorus. The surrounding muscular ring is the pyloric sphincter (valve), which controls the passage of stomach contents into the intestine. The cardia sits at the proximal end near the gastroesophageal junction, and the esophageal (lower esophageal) sphincter is at the top of the stomach, not at the lower end. The term pyloric valve refers to the sphincter itself rather than the opening.
