Where is the anal sphincter located?
Sphincters are muscular valves found throughout the body used to open or close an opening. An example is the cardiac sphincter which prevents food from coming back up the esophagus after swallowing
What receptors are stimulated in the micturition reflex?
Micturation is what we commonally call urination. There are various stretch activated receptors within the bladder and in the adjoining sphincter that participate in the reflex. The bladder has to disallow backflow and coordinate the contraction of the bladder with the relaxation of the terminal sphincter. This is done through both voluntary control of the musculature as well via sympathetic and parasympathetic reflexes.
What is the function of the Sphincter that controls the exit of the urine?
Mainly the urinary sphincters prevent the backflow of urine backwards into the bladder and the kidneys. Sphincters allow one-way flow and to prevent leakage (or in other words, prevent accidental urine loss).
What is the medical term meaning backflow of blood through the mitral valve?
Mitral regurgitation is backflow of blood through the mitral valve.
Into what chamber does the pulmonic valve prevent backflow of blood?
The pulmonic valve prevents backflow of blood into the right ventricle.
What causes gastroesophageal reflux disease?
Gastroesophageal reflux disease (GERD) is typically caused by the weakening of the lower esophageal sphincter, a muscle that acts as a valve between the esophagus and stomach. When this muscle relaxes inappropriately or becomes weak, stomach acid can flow back into the esophagus, causing symptoms such as heartburn and acid reflux. Other factors that can contribute to GERD include obesity, hiatal hernia, and certain lifestyle habits such as smoking and consuming certain foods and beverages.
What is esophageal?
Reflux esophagitis-- Inflammation of the lower esophagus caused by the backflow of stomach contents.
What is the name of the valve that prevents regurgitation of food from the small intestine back into the stomach?
epiglottis
What is the name that controls the entrance to the stomach and prevents backflow to the esophagus?
i think its the epoglotis....but im not sure
What organ is affected by heartburn?
Heartburn is reflux (backflow) of the stomach contents into the esophagus, causing burning and discomfort.
What is the purpose of gastroesophageal reflux surgery?
heartburn symptom relief and reduced backflow of stomach contents into the esophagus.
What is Guards entrances and exits of digestive system mean?
If you're referring to sphincters "guarding" entrances and exits, it means that these specific muscles close the structure to prevent backflow of body fluid. Ex: there is a sphincter between the esophagus and the stomach that "guards" the entrance to prevent the very acidic gastric juice from entering the esophagus and damaging the lining. The muscles around the eye and mouth can also be considered sphincters.

What are the valves in alimentary canal?
The gastrointestinal tract is equipped at critical junctures with a number of muscular valves, or sphincters , which, usually under the direction of the autonomic nervous system, can regulate the movement of food through the digestive tube. Another function of a sphincter is to prevent backflow of partially digested food.The first of these pursestring valves occurs at the cardia , the opening where the esophagus meets the stomach, and is called the cardiac sphincter , from its location almost directly in front of the heart. Another important muscle ring is the pyloric sphincter , at the opening called the pylorus , located at the other end of the stomach, at the connection between stomach and small intestine. The release of waste from the rectum is controlled, partly voluntarily, by an anal sphincter , located at the anus , which marks the end of the tract.
What sphincter prevents food to move from large intestine to the small intestine?
The large intestine begins at the ileocecal junction and extends to the anus. The ileocecal junction contains a muscular ring called the ileocecal sphincter, which prevents the backflow of wastes from the large intestine into the small intestine.
What is function of the pylorus?
The pylorus is also called as Pyloric Sphincter. Its two mainly functions are to prevent the food from backflow from the duodenum into the stomach and to make sure that the food that stay in the stomach is long enough after being seethe.
Are influx and reflux both real words?
