The pylorus is considered as having two parts, the pyloric antrum (opening to the body of the stomach) and the pyloric canal (opening to the duodenum). The pyloric canal ends as the pyloric orifice, which marks the junction between the stomach and the duodenum. The orifice is surrounded by a sphincter, a band of muscle, called the pyloric ...
Anatomical terminology. [edit on Wikidata] The ileocecal valve (ileal papilla, ileocaecal valve, Tulp's valve, Tulpius valve, Bauhin's valve, ileocecal eminence, valve of Varolius or colic valve) is a sphincter muscle valve that separates the small intestine and the large intestine. [1] Its critical function is to limit the reflux of colonic ...
Chyme. Chyme or chymus (/ kaɪm /; from Greek χυμός khymos, "juice" [1][2]) is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum [3] (the beginning of the small intestine). Chyme results from the mechanical and chemical breakdown of a bolus and consists of partially ...
The pyloric sphincter, at the lower end of the stomach. The ileocecal sphincter at the junction of the small intestine (ileum) and the large intestine, which functions to limit the reflux of colonic contents back into the ileum. The sphincter of Oddi, or Glisson's sphincter, controlling secretions from the liver, pancreas and gall bladder into ...
The small intestine is about 5.5 metres (18 feet) long and folds many times to fit in the abdomen. Although it is longer than the large intestine, it is called the small intestine because it is narrower in diameter. The small intestine has three distinct regions – the duodenum, jejunum, and ileum. The duodenum, the shortest, is where ...
t. e. The ileum (/ ˈɪliəm /) is the final section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms posterior intestine or distal intestine may be used instead of ileum. [2] Its main function is to absorb vitamin B 12, bile ...
It is located posterior to the liver and the gallbladder and superior to the pancreatic head. [citation needed] The gastroduodenal artery, [3] portal vein, and common bile duct are situated posterior to the duodenal bulb. The distal part of the bulb is located retroperitoneally. It is located immediately distal to the pyloric sphincter ...
The proventriculus is a standard part of avian anatomy, and is a rod shaped organ, located between the esophagus and the gizzard of most birds. [2] It is generally a glandular part of the stomach that may store and/or commence digestion of food before it progresses to the gizzard. [3] The primary function of the proventriculus is to secrete ...
