Sphincters prevent material from flowing backwards, like the pyloric sphincter in the stomach.
Precapillary sphincters control blood flow into capillaries, regulating the distribution of oxygen and nutrients to tissues based on demand. Constriction of these sphincters reduces blood flow while relaxation increases blood flow, ensuring efficient delivery of resources to active tissues.
A sphincter is a circular band of muscle tissue that, when contracted, cuts off the flow of material from one place to another. There are two urinary sphincters, one at the base of the bladder and one at the pelvic canal along the urethra. The purpose of both sphincters is to prevent urinary leakage.

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.
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.
