The spincters located in the esophagus are: the upper sphincter at the top and the lower (the cardiac sphincter) at the bottom of the esophagus. They regulate the food passing through the esophagus.
the lower oesophageal sphincter
and the one that allows entry into the duodenum (small intestine) is the pyloric sphincter.
the pyloric sphincter is at the end of the pyloric stomach which is the lower end
i dont know exact name but it is a smooth muscle. smooth muscle is the term usually used.
The pyloric sphincter.
anus
I will take a guess at this question. I think it is the Cardiac Sphincter.
The pyloric sphincter regulates passage of chymefrom the stomach
The English name is pyloric sphincter (i.e. pylori has a c at the end). The Latin is sphincter pylori. This is a sphincter muscle at the lower end of the stomach controlling the amount of food being released into the duodenum.

The large end of the pigs digestive tract
The gastrointestinal tract is equipped at critical junctures with a number of muscular valves, or sphincters , which, usually under the direction of the autonomic nervous system, can regulate the movement of food through the digestive tube. Another function of a sphincter is to prevent backflow of partially digested food.The first of these pursestring valves occurs at the cardia , the opening where the esophagus meets the stomach, and is called the cardiac sphincter , from its location almost directly in front of the heart. Another important muscle ring is the pyloric sphincter , at the opening called the pylorus , located at the other end of the stomach, at the connection between stomach and small intestine. The release of waste from the rectum is controlled, partly voluntarily, by an anal sphincter , located at the anus , which marks the end of the tract.
The ring of muscle at the entrance to the stomach is the lower esophageal sphincter. This muscle is normally contracted to close the esophagus. At the lower end of the stomach food passes through the pyloric sphincter and into the duodenum of the small intestine.
Both the upper and lower ends of the stomach have a sphincter that regulates flow into and out of the stomach. The lower esophageal sphincter is at the top of the stomach, and the pyloric sphincter is at the lower end of the stomach.
Both are ring like muscles and keep something in. They are both part of the digestive tract. A cardiac Sphincter is a tight ringlike muscle at the end of the esophagus, and before the stomach that keeps a horse from belching or vomiting. A pyloric Sphincter is basic anatomy for anyone. This is also a tight ring like muscles at the end of the stomach that keeps the stomach acids in the stomach and not spilling into the rest of the digestive tract.
