  2. Gastric glands - Wikipedia

    en.wikipedia.org/wiki/Gastric_glands

    The gastric glands are glands in the lining of the stomach that play an essential role in the process of digestion. All of the glands have mucus-secreting foveolar cells (also known as surface mucous cells) that line the stomach and partly line the gastric pits, and mucus-secreting mucous neck cells in the necks of the gastric glands.

  3. Gastrointestinal physiology - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_physiology

    Mucus is made by two types of specialized cells termed mucous cells in the stomach and goblet cells in the intestines. Signals for increased mucus release include parasympathetic innervations, immune system response and enteric nervous system messengers.

  4. Intestinal gland - Wikipedia

    en.wikipedia.org/wiki/Intestinal_gland

    The Brunner's glands secrete large amounts of alkaline mucus in response to (1) tactile or irritating stimuli on the duodenal mucosa; (2) vagal stimulation, which increases Brunner's glands secretion concurrently with increase in stomach secretion; and (3) gastrointestinal hormones, especially secretin. [6]

    For decades, it was believed that the main function of the glands is to secrete alkaline (bicarbonate-containing) mucus in order to: [citation needed] protect the duodenum from the acidic content of chyme (which enters the duodenum from the stomach), provide an alkaline environment which promotes the activity of intestinal enzymes,

  6. Gastrointestinal wall - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_wall

    In the large intestines, villi are absent and a flat surface with thousands of glands is observed. Underlying the epithelium is the lamina propria, which contains myofibroblasts, blood vessels, nerves, and several different immune cells, and the muscularis mucosa which is a layer of smooth muscle that aids in the action of continued peristalsis ...

  7. Gastrointestinal tract - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_tract

    The lower gastrointestinal tract includes most of the small intestine and all of the large intestine. [15] 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 ...

    The cecum is a pouch marking the division between the small intestine and the large intestine. It lies below the ileocecal valve in the lower right quadrant of the abdomen. [33] The cecum receives chyme from the last part of the small intestine, the ileum, and connects to the ascending colon of the large intestine. At this junction there is a ...

    Other mucus-secreting cells are the mucous neck cells in the necks of the gastric glands. [2]: 257 Surface mucous cells have large quantities of mucin granules in their apical (top) surface and project short microvilli into the lumen of the stomach. [2]: 257 Mucins are large glycoproteins that give the mucus its gel-like properties. [3]
