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 is the saclike organ at the end of the esophagus called?
Did you mean 'bag like organ' The stomach is part of the digestive system, which is sometimes called the gastrointestinal tract. It is a muscular, bag-like organ which lies between the lower end of the gullet (oesophagus) and the beginning of the small bowel (small intestine). Once food has been swallowed it passes down the gullet and into the stomach. Both ends of the esophagus are closed off by muscular constrictions known as sphincters; at the anterior, or upper, end is the upper esophageal sphincter, and at the distal, or lower, end is the lower esophageal sphincter. The cardia (also known as Z-line or esophagogastric junction or gastroesophageal junction) is the anatomical term for the junction orifice of the stomach and the esophagus. At the cardia, the mucosa of the esophagus transitions into gastric mucosa. The cardia is also the site of the lower esophageal sphincter (LES) (also termed cardiac sphincter, gastroesophageal sphincter, and esophageal sphincter).
Precapillary sphincter is used for what purpose?
Precapillary sphincters are small, ring-like muscles that can close or open parts of a capillary bed, depending on the oxygen and nutrient demands for the tissue
How many variors diaphragms in human body?
There are actually 8 diaphragms in the human body:Tentorum cerebelliPituitary diaphragm (covering the pituitary at the level of the stalk)Occipital bone on the AtlasThoracic inletThoracoabdominal diaphragmPelvic diaphragmPopliteal fossaand the arch of the footPELVIC DIAPHRAGMmuscular part of the pelvic floor, consists of the muscles levator ani and coccygeus. separates pelvic cavity from perineum. levator ani reinforces the external anal sphincter, and in women functions as a vaginal sphincter. it is these muscles we are strengthening when doing pelvic floor exercises. the pelvic diaphragm supports the pelvic viscera (ie. the bladder), as well as providing an attachment for the perineum (external genitals). these muscles originate across the wall of the pelvis (from posterior aspect of pubic bone to ischial spine) and insert either into one another at the midline, or into the sacrum/coccyx/anococcygeal ligament.THORACIC DIAPHRAGMthin muscular structure that separates the thoracic cavity from the abdominal cavity (in other words separates lungs, heart etc. from stomach, intestines etc.) this muscle is just known as the diaphragm. it attaches to the sternum at the front (specifically xiphisternum), some of the ribs, and vertebrae of the lumbar spine. it is shaped like a dome, and has a central tendon at its top/middle into which it inserts from all angles. the role of this muscle is in breathing, as when it contracts it allows the lungs to expand and fill with air, and as it relaxes again the air is pushed out of the lungs. the aorta, inferior vena cava and the oesophagus are the 3 major structures which pierce the diaphragm in order to pass between abdominal and thoracic cavities.
What is the function of the Pyloric opening?
Pyloric sphincter function is to push digested food from the lower part of the stomach into the Duodenum. It does this by the Sphincter muscle (circular muscle at an orifice) contracting closing the opening, then when relaxed it openings. this is done involuntarily. Kinda like passing stool, the sphincter muscle in the rectum (the anus) contracts and relaxes pushing the stool out of orifice, However, this is done voluntarily when constipated.

Ring like muscle that controls the flow from the stomach to the small intestine?
lower esophageal sphincter or gastroesophageal sphincter
Is the ring like muscle that controls the flow from the stomach to the small intestine?
The ring like muscle that controls the flow from the stomach to the small intestine is called the pylorus or the pyloric sphincter. It is divided into two parts: the pyloric antrum which is connected to the body of the stomach and the pyloric canal which is connected to the beginning of the small intestine (the duodenum).
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 is a ring like mucle that tighly constrict the opening of a passasseway?
sphincter
What does a girl's anal sphincter look like?
Use a mirror. It looks a lot like yours.
What close like a rubber band around the opening of the bladder?
sphincter muscles
What closes like a rubber band around the opening of the bladder?
sphincter muscles
What are ring of muscles?
Proper rings are only formed by smooth mucle and are called sphincters. NB not all sphoncters are proper ring.
What is the function of internal sphincter?
its like a valve that opens when the when ur ready 2 excrete
What is the purpose of sphincters?
Sphincters prevent material from flowing backwards, like the pyloric sphincter in the stomach.
