What is the name of the sphincter that opens when food or fluids exert pressure on it?
Esophageal, duodenal, urethral, and anal would all seem to fit that description.
What is the function of internal sphincter?
its like a valve that opens when the when ur ready 2 excrete
What opens and closes because of turgor pressure?
underground
What structure opens to equalize pressure in the ear?
eustachian tube
What is the cardioesophageal sphincter?
The oesophagus is the first part of the alimentary tract after the oropharynx. The cardio-oesophageal junction is the point where the oesophagus meets the stomach (at it's cardiac end - meaning the part of the stomach closer to the heart), where there is a circumferential thickening of the muscles in the wall of the gastrointestinal tract (tube). This extra thickening in the muscle layer is called the cardio-oesophageal sphincter. When food swallowed reaches this part, the sphincter dilates (expands/opens) to allow food to pass through from the oesophagus to the stomach. Once the food passes, the sphincter contracts (narrows/closes down) to prevent the contents of the stomach from returning back to the oesophagus. Regurgitation of stomach contents and resultant vomiting occurs when the functioning of this sphincter becomes defective.
What sphincter that opens when food or fluids exert pressure on it?
The sphincter that opens when food or fluids exert pressure on it is the gastroesophageal sphincter. Closure of the sphincter is under the control of the vagus nerve.
What is the name of the sphincter that opens when food or fluids exert pressure on it?
Esophageal, duodenal, urethral, and anal would all seem to fit that description.
What fluid pressure opens the atrioventricular allowing blood to enter the next chamber?
the aorta that fluid that enters
What spincter opens when food or fluids exert pressure on it?

What Muscle that opens to allow urine to be removed from the bladder?
sphincter
Does pyloric sphincter opens 3 times in a minute?
yes
What pH level opens the pyloric sphincter?
at the level of the first lumbar vertebra
What role do the sphincter muscles play in digestion?
The lower esophageal sphincter keeps food from coming back up, or vomiting. When you have to vomit, the sphincter opens allowing the food to come back up. There is another sphincter, the pyloric sphincter which leads into the small intestine. Hope this helps!
What is a sphincter in the digestive system?
The pyloric sphincter regulates passage of chymefrom the stomach
What is the function of internal sphincter?
its like a valve that opens when the when ur ready 2 excrete
How does the cardiac and pyloric help with digestion and absorpation?
The pyloric sphincter is a valve that opens and closes to allow chyme to leave the stomach and enter the duodenum. The cardiac sphincter is a valve that opens and closes to prevent stomach acid from going up the esophagus.
Sphincter controlling the movement of food from the stomach into the duodenum?
Pyloric sphincter controls the movement of food from stomach to duodenum. With parasympathetic or vagal stimulation it opens up or relaxes and with sympathetic stimulation it contracts or closes.
