    Alkaline mucus exists in the human eye, stomach, saliva, and cervix. [5] In the stomach, alkaline mucus is secreted by gastric glands in the gastric mucosa of the stomach wall. [6] Secretion of alkaline mucus is necessary to protect the mucous membrane of the stomach from acids released during digestion. [6]

  4. Gastrointestinal physiology - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_physiology

    Every day, seven liters of fluid are secreted by the digestive system. This fluid is composed of four primary components: ions, digestive enzymes, mucus, and bile. About half of these fluids are secreted by the salivary glands, pancreas, and liver, which compose the accessory organs and glands of the digestive system.

  5. Intestinal mucosal barrier - Wikipedia

    en.wikipedia.org/wiki/Intestinal_mucosal_barrier

    The mucus prevents large particles from contacting the epithelial cell layer while allowing small molecules to pass. The mucus also facilitates passage of the luminal contents along the length of the intestines, protects the epithelial cells from digestive enzymes, and prevents the direct contact of microorganisms with the epithelial layer.

  6. Gastrointestinal wall - Wikipedia

    en.wikipedia.org/wiki/Gastrointestinal_wall

    It is where most digestive, absorptive and secretory processes occur. The lamina propria, a layer of connective tissue within the mucosa. The muscularis mucosae, a thin layer of smooth muscle.

    Mucous membranes line the digestive, respiratory and reproductive tracts and are the primary barrier between the external world and the interior of the body; in an adult human the total surface area of the mucosa is about 400 square meters while the surface area of the skin is about 2 square meters.

  9. 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.
