During what process does the cardiac sphincter open involuntarily?
the cardiac sphincter opens involuntarily during peristalsis, which is the process of wavelike muscle contractions of the alimentary tract that moves food along the oesophagus down to 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.
What is the difference between an orifice and sphincter?
The orifice is an opening such as the nostrils, mouth, etc. The sphincter is a muscle. These are like valves that only allow certain materials to go in and out and are often very tight, resulting in the action of peristalsis.
What causes vomiting and inability to open eyes?
Vomiting and inability to open eyes can be caused by a variety of conditions, such as severe dehydration, migraine headaches, inner ear disorders, or a reaction to certain medications. It is important to seek medical attention to determine the underlying cause and receive appropriate treatment.
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 sphincter must open to prevent vomiting?
ugly
What happens for micturition to occur?
1) The detrusor muscle must contract 2) The internal urethral sphincter must open 3)The external urethral sphincter must open
What process does cardiac sphincter open involuntary?
Peristalsis.
During what process does the cardiac sphincter open involuntary?
Peristalsis.
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.
What is the age requirement for the new Tennessee open carry laws?
There is no statutary limit on age for open carry. BUT you must have a gun permit which has an age requirement of 21 years.
How does pyloric sphincter know when to open to let out a little chyme and then close?
The pyloric sphincter opens in response to food entering the stomach. Stretch receptors in the stomach wall detect the food volume, signaling the sphincter to open and allow a controlled amount of chyme to pass into the small intestine for further digestion. Once the chyme has passed through, the sphincter closes to prevent backflow.
What is a muscle that acts as bowels to open and close the openings are called what type of muscle?
sphincter
How does bulimia affect the esophagus?
The stomach acid (hydrochloric acid) that breaks down your food is extremely powerful, so, constant vomiting will wear away the lining of your esophagus. Eventually, you may wear holes in your esophagus, which can be fatal. Even if this doesn't happen, you will most likely have acid reflux for the rest of your life, since all the vomiting weakens your cardiac sphincter, which is basically like the lid of your stomach: it keeps the acid from splashing up into your esophagus. After years of vomiting many times a day, the sphincter constantly flaps open like the lid of a garbage can.
What sphincter controls the release of bile and pancreatic juice into the small intestine?
The sphincter of Oddi (hepatopancreatic sphincter), controls the release of pancreatic enzymes and bile into the duodenum. During digestion, intestinal phase signals stimulate the release of bile.
What causes the gastroesophageal sphincter to open to allow food to enter the stomach?
the arrival of the peristaltic wave at the stomach
How does pyloric sphincter knows to open for chyme and when to close?
The pyloric sphincter opens in response to the presence of acidic chyme in the stomach. This triggers hormonal and neural signals that stimulate the sphincter to relax and allow the chyme to pass into the small intestine. Once the chyme has been emptied, feedback mechanisms signal the pyloric sphincter to close to prevent backflow of contents into the stomach.
