Detailed Solution

Concept- There are major 5 sphincters that are shown within the nourishment canal.
Esophageal sphincter: Reduces backflow from throat to pharynx and allows bolus passage into the throat.
The cardiac sphincter displays the point at which the neck and stomach converge.
The pyloric sphincter, located at the connection between the stomach and the small digestive tract, is seen at the aperture of the pylorus. It enables the duodenum to get small amounts of nutrition at once.
The butt-centric/anal sphincter is located there and only partially regulates waste evacuation from the body.
The ileo-caecal valve could be a sphincter muscle where the small and large digestive systems converge. It reduces colonic material reflux into the ileum.
Hence, the correct answer is option 4.
