If the stomach did not have sphincter muscles, it would lead to uncontrolled movement of food and gastric contents. This could result in the backflow of stomach acid into the esophagus, causing acid reflux or gastroesophageal reflux disease (GERD). Additionally, the inability to regulate the passage of food into the intestines could disrupt digestion and nutrient absorption, leading to potential malnutrition and digestive disorders. Overall, sphincter muscles play a crucial role in maintaining digestive health and function.
If the pyloric sphincter were to become parlyzed, therefore remaining in the open position, gastric contents would move very quickly through the stomach into the duodenum and intentestinal tract. Under normal conditions, when the stomach is empty, the sphincter relaxes, allowing the first several bites of food to reach the stomach to move on to the intestines for immediate absorption. After these arrive, the sphincter closes and reopens periodically to manage the flow of partially digested food. In the event this were to be stuck open, one would expect to experience a number of problems. Firstly, the feeling of never being full after eating. Secondly, allowing large quantities of under-digested food to reach the intestinal tract would likely cause constipation and therefore dysfunction of the absorption process, eventually leading to intestinal obstruction.
The anal sphincter and the bladder sphincter in potty trained children and in most other people whose spinal cords are intact or are not suffering from some diseases.
A cholinergic agonist will cause the pyloric sphincter to relax, leading to increased gastric emptying. This is because cholinergic stimulation promotes smooth muscle relaxation in the gastrointestinal tract, allowing food to pass through the pyloric sphincter more easily.
If the sphincter muscle, such as the anal sphincter, were severed, it could lead to issues with bowel control, resulting in fecal incontinence. Surgical intervention may be necessary to repair or reconstruct the sphincter to restore proper function. Physical therapy and lifestyle modifications may also be needed to manage symptoms.
The sphincter that opens when food or fluids exert pressure on it is called the lower esophageal sphincter (LES).
If you are referring to the digestive system, I believe this would be the pyloric sphincter. After the stomach turns dry food into a wet mass, it delivers it to the duodenum via the pyloric sphincter (muscle).
Well, your anus contains the anal sphincter which, technically, is an opening of the body. So I would probably say the answer you are looking for is a sphincter muscle. Otherwise known as circular muscles
some examples of the sphincter muscle are, the anus (not even joking, if we didn't have one there, we would poop our pants without controlling it lol), the intestines, stomach, bile duct, and uterus.
One example of involuntary muscles would be in the digestive system, where muscles in the stomach churn food.
If you are vomiting it does. But usually food doesn't go back into the esophagus because it tends to go down hill, going back into the esophagus is going against gravity. ---------- Also, the lower esophageal sphincter normally prevents stomach contents from flowing backwards. Sphincters are rings of muscle that open and close to control the flow in various places in the body.
If such things were voluntary we would not exist.
The sphincter that controls the pupil of the eye.
Muscles cause contraction. Contraction aides in moving the food along.

There are 2 anal sphincter's; if they fail then feces will drip out of the anus.

No mules cannot vomit. This is due to the cardiac sphincter located at the bottom of the esophagus, this sphincter only moves one way, allowing food only to travel into the stomach and not back into the esophagus.
