Sphincters are circumferential muscles that can relax or constrict to regulate the passage of material through a particular area. The stomach is bound by two sphincters in humans: the lower esophageal sphincter that keep stomach acid in the stomach and the pyloric sphincter that regulates the flow of food in the stomach into the duodenum.
The pyloric sphincter, at the lower end of the stomach and The cardia/lower esophageal sphincter, or cardiac sphincter at the upper portion of the stomach
Cardiac sphincter regulates entry into the stomach The pyloric sphincter regulates exit from the stomach.
The cardiac (entry) and the pyloric (exit) sphincters.
sphincters
These rings of muscle are not only found either end of the stomach, but also at the base of the bladder. They are called sphincters. The lower sphincter in the stomach is specifically known as the pyloric sphincter, but I regret to say I do not know the exact names given to other sphincters.

Sphincters prevent material from flowing backwards, like the pyloric sphincter in the stomach.
cardiac and pyloric
there 2 kinds of sphincters the cardiac and pyloric the cardiac prevents the bolus from going back to the oesophagus cardiac sphincters allows the bolus to enter the stomach the pyloric sphincters prevents food from going to the duodenum the pyloric sphincter allows the chyme to enter the duodenum hope it was helpful :)
I can think of 5 off the top of my head. Cardiac Sphincter at the top of the stomach. Pyloric Sphincter at the distal end of the stomach. Ileocecal Valve that separates the Small and Large intestines and the Internal and External Anal sphincters.
mouth, esophagus, stomach, small intestine, large intestine. There are sphincters at the two ends of the stomach, and the intestines are separated into different sections, with the anus being 2 sphincters as well. Other organs, such as the pancreas, gallbladder are used for the excretion of digestive juices.
Sphincters are in the digestive tract and urinary tract. They act as one-way doors to prevent backflow. So once foodstuffs enter the small intestines, it cannot go backward back into the stomach.
Pyloric and cardiac sphincters .
40 including the eye, mouth, esophagus, urethra, stomach, upper intestiens, lower intestines, anus etc.
