What role do the sphincter muscles play in digestion?

What is a sphincter in the digestive system?
The pyloric sphincter regulates passage of chymefrom the stomach
What causes the internal urethral sphincter to open?
The internal urethral sphincter opens in response to signals from the autonomic nervous system, particularly the parasympathetic nervous system. This relaxation allows urine to flow from the bladder into the urethra for expulsion.
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.
Which sphincter allows for defecation and is under voluntary control?
The external anal sphincter is under voluntary control. You have the urge to defecate because your internal anal sphincter involuntarily opens, but you can keep yourself from going to the bathroom because your external anal sphincter is voluntarily closed. Hope that helps!
What makes the pyloric sphincter open and close?
The pyloric sphincter opens in response to the presence of food in the stomach. This triggers a reflex that relaxes the sphincter, allowing food to pass into the small intestine. The sphincter closes to prevent the backflow of intestinal contents back into the stomach.
