Keeping this in view, what valve opens from the esophagus to the stomach? lower esophageal sphincter (LES) Subsequently, question is, what is the name of the sphincter that separates the stomach from the small intestine? The pyloric antrum is the initial portion of the pylorus. It is near the bottom of the stomach, proximal to the pyloric sphincter, which separates the stomach and the duodenum. One may also ask, how does the stomach empty into the small intestine? The duodenum is the first segment of the small intestine, and the stomach releases food into it. Food enters the duodenum through the pyloric sphincter in amounts that the small intestine can digest. When full, the duodenum signals the stomach to stop emptying.What opens the pyloric sphincter?With each wave, the pyloric sphincter opens and allows a little bit of chyme to pass into the duodenum. As the duodenum fills, it puts pressure on the pyloric sphincter, causing it to close. The duodenum then uses peristalsis to move the chyme through the rest of the small intestine.
