The muscle located at the end of the esophagus that guards the stomach opening is the?
The Lower Esophageal Sphincter.
What is the difference between an orifice and sphincter?
The orifice is an opening such as the nostrils, mouth, etc. The sphincter is a muscle. These are like valves that only allow certain materials to go in and out and are often very tight, resulting in the action of peristalsis.
What hormone causes the opening of the sphincter of oddi?
The sphincter of Oddi regulates the passage of pancreatic juices and bile into the duodenum of the small intestine.
What is the function of the phyloric sphincter?
The pyloric sphincter regulates the flow of partially digested food from the stomach to the small intestine. It ensures that the food is released in a controlled manner, allowing for proper digestion and absorption of nutrients.
What is between stomach and small intestine?
The opening between the stomach and the small intestine is called the Pyloric Sphincter- it is a ring of muscle that contracts when the stomach is full, to seal off the opening to the small intestine whilst foodstuffs are liquified in the stomach. When this has been done, the sphincter muscle relaxes, re-opening the channel to allow the liquified nutrients into the intestines.
What is the sphincter of boyden?
the sphincter of boyden surrounds the opening of bile duct into the pancreatic duct
What kind of muscle controls a circular opening?
A sphincter muscle controls a circular opening in the body. It serves to regulate the passage of substances through the opening by contracting or relaxing. Examples include the anal sphincter and the sphincter muscles in the digestive system.

What are the two openings at the end of the stomach?

What muscle controls the diameter of an opening?
The muscle that controls the diameter of an opening is called a sphincter muscle. Sphincter muscles are circular bands of smooth muscle that encircle openings in various parts of the body, such as the digestive system and urinary tract. They contract to close the opening and relax to allow passage, thus regulating the flow of substances through these openings. Examples include the anal sphincter and the pyloric sphincter in the stomach.
What is a ring like mucle that tighly constrict the opening of a passasseway?
sphincter
What is a sphincter structures?
a ring of muscle that controls the release of an organs products. EXAMPLE: Pyloric Sphincter controls release of chyme. Cardiac Sphincter controls deposition of food into the stomach from the esophagus. External Urethral Sphincter controls release of urine. External Anal Sphincter controls release of defecation.
Which hormone will stimulate the opening of the pyloric sphincter?
Gastrin is the hormone that stimulates the opening of the pyloric sphincter. It is secreted by the stomach in response to the presence of food and stimulates the release of gastric acid as well as the relaxation of the pyloric sphincter to allow food to pass from the stomach to the small intestine.
