The fundus stores both undigested food and gases that are released during the process of chemical digestion. Food may sit in the fundus of the stomach for a while before being mixed with the chyme. While the food is in the fundus, the digestive activities of salivary amylase continue until the food begins mixing with the acidic chyme.
The parietal cells in the fundus of the stomach, produce a glycoprotein called intrinsic factor which is essential for the absorption of vitamin B12. Vitamin B12 (cobalamin), is carried to, and through the stomach, bound to a glycoprotein secreted by the salivary glands – transcobalamin I also called haptocorrin, which protects the acid ...
The greater curvature of the stomach forms the lower left or lateral border of the stomach. [3] Starting from the cardiac orifice it begins at the cardiac notch, forming an arch backward, upward, and to the left. A horizontal plane across from the cardiac notch encloses an area called the fundus of the stomach.
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.
The major type of gastric gland is the oxyntic gland that is present in the fundus and the body of the stomach making up about 80 per cent of the stomach area. These glands are often referred to simply as the gastric glands .
This allows the stomach to expand, therefore increasing the volume of the stomach without increasing pressure. [2] They also provide the stomach with an increased surface area for nutrient absorption during digestion. [2] Gastric folds may be seen during esophagogastroduodenoscopy or in radiological studies. [3] [4]
The pylorus (/ p aɪ ˈ l ɔːr ə s / or / p ɪ ˈ l oʊ r ə s /) connects the stomach to the duodenum. 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
Gastric chief cells are generally located deep in the mucosal layer of the stomach lining, in the fundus and body of the stomach. [2] [3] Chief cells release the zymogen (enzyme precursor) pepsinogen when stimulated by a variety of factors including cholinergic activity from the vagus nerve and acidic condition in the stomach.
