When sphincters relax, they allow the passage of substances through the openings they control. For example, when the lower esophageal sphincter relaxes, it permits food to enter the stomach from the esophagus. Similarly, relaxation of the anal sphincter allows for the expulsion of feces. This relaxation is a crucial part of various physiological processes, including digestion and elimination.
The muscularis layer of the gastrointestinal (GI) tract is responsible for forming sphincters. These sphincters help regulate the passage of food and fluids through different parts of the GI tract, such as the lower esophageal sphincter, pyloric sphincter, and anal sphincter.
A sphincter is a band of muscles that surround an opening. The most well known sphincters are those of the anus. The anal sphincters are what controls fecal matter leaving the body. They both hold the fecal matter in place and help you to expel it. However, you also have sphincters in other places such as the eyes and the top of the stomach. In the eyes, they are also known as the iris, and they control the amount of light entering. At the top of the stomach, that is to help prevent stomach acid from coming up. When this band of muscles start to fail, acid reflux is a symptom.
The gastrointestinal tract contains sphincters, which are circular muscles that regulate the movement of material through the digestive system. Some examples of sphincters in the gastrointestinal tract include the lower esophageal sphincter, pyloric sphincter, and anal sphincter.

The three major sphincters in the human body are located in different areas. The upper esophageal sphincter is found at the top of the esophagus, controlling the passage of food from the throat into the esophagus. The lower esophageal sphincter is located at the junction of the esophagus and stomach, preventing acid reflux. The anal sphincter is situated at the end of the rectum, regulating the expulsion of feces from the body.
Mostly because they have lost control of body function, and their muscles and sphincters have relaxed. It isn't a phenomenon limited to heart attacks either, it happens to pretty much everyone that dies.

Sphincters prevent material from flowing backwards, like the pyloric sphincter in the stomach.

Sphincters
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 Precapillary Sphincters control blood pressure and body temperature by regulating the flow of blood to the capillary bed.
