The iliocecal sphincter
The ileum is the last (and longest) portion of small intestine. It empties into into the cecum (the first part of the "large intestine") at the iliocecal junction. The iliocecal sphincter is a ring of invountary smooth muscle at this junction, controlling the passage of digestive contents from the small intestine to the large intestine.
The pyloric sphincter
The ring of muscle that controls the passage of material from the stomach into the small intestine.
The pyloric sphincter regulates the passage of chyme into the duodenum (sm. intestine).
It is called pyloric sphincter and it regulates the passage of digested food from the stomach onto the duodenum ( small intestine ).
The vagus nerve controls the pyloric valve. It helps regulate the passage of food from the stomach to the small intestine by controlling the muscular movement of the pyloric valve.
They are variable controls which can open to allow the passage of material and then closed to prevent further passage of materials. If you didn't have an anal sphincter you'd really have problems.
The valve that controls the movement of food between the stomach and small intestine is called the pyloric sphincter. It regulates the passage of partially digested food from the stomach into the small intestine for further digestion and absorption.

The medical term for circular muscle found in tubular structures that regulates the passage of substances is "sphincter." Sphincters act as valves to control the flow of fluids or materials through tubular structures in the body.

Microvilli and tight junctions are two structures present in epithelial cells from the small intestine that are not present in cholera bacteria. Microvilli increase the surface area for nutrient absorption, while tight junctions help to form a barrier between cells to regulate the passage of molecules. Cholera bacteria cause an infection in the intestine but lack these typical cell structures as they are single-celled organisms.
The pyloric sphincter valve is a ring of muscle at the exit of the stomach that controls the flow of partially digested food (chyme) into the small intestine. It functions by regulating the passage of chyme from the stomach in small amounts to aid in digestion and prevent the small intestine from being overwhelmed.
