How does pyloric sphincter knows to open for chyme and when to close?
It is a combination of hormones, brain signals, and sensor tissue near the sphincter.
What makes the pyloric sphincter open and close?
acidic ph
Why can't you feel your stomach squeezing and opening?
You actually can. If you pay close attention the next time you burp, you may notice a 'relaxing' feeling deep in your belly. This is the lower valve, called the pyloric sphincter, opening to allow gas from your small intestine into your stomach, and then the upper valve, the esophageal sphincter, open and release the belch into your esophagus with the final result being your vocal cords in your larynx vibrating to make that familiar sound we all know and love as a burp!
Where is the orbicularis oris located?
The orbicularis oculi is a muscle in the face that closes the eyelids. It also aids with the flow of tears over the surface of the eye.
How do you hold on to your pee?
The urinary bladder and urethra uses a sphincter. A sphincter is a tight band of muscular tissue that acts like a "door". The door is designed to only open under certain circumstances. For humans, this means we hold our urine until we find a toilet. Then, the sphincter opens and urine flows out.There can be problems with the sphincter, including being young. As young children, we learn over time to interpret the urge signal from our bodies, and to stop our activities and find a bathroom. Even children in grade school can still have occasional accidents. The key is to STOP whatever you are doing, and go to the bathroom.Women who have had one or more children, or who have had repeated bladder/urethral infections can also find they have more bladder irritability and the sphincter does not close as well as in younger ages. Talk to your doctor.

Circular muscles that close a tube when they contract?

Ring of muscle in the stomach?
The ring of muscle at the entrance to the stomach is the lower esophageal sphincter. This muscle is normally contracted to close the esophagus. At the lower end of the stomach food passes through the pyloric sphincter and into the duodenum of the small intestine.
What are the functions of a cardiac sphincter?
The function of the cardiac sphincter is to prevent a back flow of materials back into the esophagus. The cardiac sphincter closes to allow the food to stay within the stomach so it can be digested. Cardiac sphincter, working with the pyloric sphincter keeps the stomach content from moving elsewhere.
What controls the passage of material from the small intestine to the large intestine?
There are structural (anatomical) and functional (physiological) ways the digestive system regulates how food is passed from the stomach to the small intestine. The major anatomical regulators are the pyloric sphincter (a muscular band that acts like a valve to open and close the connection between the stomach and small intestine) and the pyloric antrum (the part of the stomach commonly associated with stomach motility, mixing, and propulsion of stored foodstuffs into the small intestine). When the pyloric sphincter is relaxed and the antrum is active, food is propelled into the small intestine; when the sphincter is constricted and the antrum is relaxed, food is stored in the stomach. A number of physiological factors exist that regulate the activity of the pyloric sphincter and antrum. The principal regulators are nerves and hormones involved in the digestive process. The vagus nerve is an example of a nerve with major regulatory effects on motility of the stomach and small intestine. Gastrin and cholecystokinin (CCK) are gut hormones also involved in stomach motility. Gastrin is secreted in response to food (particularly amino acids, the building blocks of proteins) in the stomach and stimulates antral motility that serves to mix food. Strong antral contractions cause opening of the pyloric sphincter and the movement of food into the small intestine. CCK is released in response to foodstuffs (particularly fats) in the small intestine and inhibits antral motility of the stomach.
The is a circular muscle located at the entrance and exit to the stomach?
LES-Lower Esophageal Sphincter aka Cardiac Sphincter prevents stomach contents from entering the esophagus.UES-Upper Esphageal Sphincter- Reduces air entering the stomachPyloric Sphincter is found at the end of the stomach and control the release of food from the stomach to the small intestine.

It is known as the lower esophageal sphincter or sometimes the cardioesophageal sphincter.

This depends on what sphnicter muscle you are talking about, because there is more than one sphincter muscle in a cow.
