The pyloric sphincter, surrounding the pyloric orifice is a strong ring of smooth muscle at the end of the pyloric canal which lets food pass from the stomach to the duodenum. It acts as a valve , controlling the outflow of gastric contents into the duodenum [ 6 ] and release of chyme .
The duodenal bulb (also ampulla of duodenum, duodenal ampulla, or duodenal cap) is the initial, dilated portion of (the superior part of) the duodenum [1] just distal to the stomach; it begins at the pylorus and ends at the neck of the gallbladder. It is normally about 5 centimeters long.
Gastric outlet obstruction (GOO) is a medical condition where there is an obstruction at the level of the pylorus, which is the outlet of the stomach. Individuals with gastric outlet obstruction will often have recurrent vomiting of food that has accumulated in the stomach, but which cannot pass into the small intestine due to the obstruction ...
The pylorus (from Greek 'gatekeeper') connects the stomach to the duodenum at the pyloric sphincter. The cardia is defined as the region following the "z-line" of the gastroesophageal junction , the point at which the epithelium changes from stratified squamous to columnar .
Prolonged bleeding may cause anemia leading to weakness and fatigue. Inflammation of the pyloric antrum, which connects the stomach to the duodenum, is more likely to lead to duodenal ulcers, while inflammation of the corpus may lead to a gastric ulcer. Stomach cancer can cause nausea, vomiting, diarrhoea, constipation, and unexplained weight ...
In human anatomy, the intestine (bowel or gut; Greek: éntera) is the segment of the gastrointestinal tract extending from the pyloric sphincter of the stomach to the anus and as in other mammals, consists of two segments: the small intestine and the large intestine.
In the pyloric region the glands are known as pyloric glands, and in the rest of the stomach they are called gastric glands. [1] Several types of endocrine cells are found in the gastric glands. The pyloric glands contain gastrin-producing cells ; this hormone stimulates acid production from the parietal cells.
Chyme or chymus (/ k aɪ m /; 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).
