I believe that it is called the Pyloric Sphincter.
The Pyloric Sphincter.
The Pylorus (the valve between the stomach and duodenum is the pyloric valve)
The cardiac sphincter is located at the top of the stomach and controls the direction of food passing through the esophagus so that no food will re enter the esophagus. The Pyloric sphincter stops bile and digested food from entering the stomach, this valve is located at the bottom of the stomach.
A band of muscles at the opening of the stomach called the Cardiac (due to its proximity to the heart) Sphincter.
epiglottis
At the bottom of the stomach. When the pylorus opens, it lets partially digested foor or water into the duodenum (top part of small intestine.)
When food reaches the bottom of the esophagus, it enters the stomach through the lower esophageal sphincter (LES). This muscular valve opens to allow the food to pass into the stomach, where it is mixed with gastric juices for further digestion. The LES then closes to prevent stomach contents from flowing back into the esophagus.
The stomach and first part of the small intestine (duodenum) is connected by pylorus which has 2 parts. The on the stomach opening is called pyloric antrum and the opening in the duodenum is the pyloric canal type.
Alcohol consumption can relax the pyloric valve, which is a muscle at the bottom of the stomach that controls the flow of food into the small intestine. This can lead to faster emptying of the stomach contents into the small intestine, potentially causing issues with digestion and absorption of nutrients.
