  3. Mucous membrane - Wikipedia

    en.wikipedia.org/wiki/Mucous_membrane

    For instance, mucosa in the stomach protects it from stomach acid, [2]: 384, 797 and mucosa lining the bladder protects the underlying tissue from urine. [8] In the uterus, the mucous membrane is called the endometrium, and it swells each month and is then eliminated during menstruation. [2]: 1019

  4. Gastric glands - Wikipedia

    en.wikipedia.org/wiki/Gastric_glands

    The secretions of the different exocrine gastric gland cells produce a watery, acidic fluid into the stomach lumen called gastric juice. [5] [6] Gastric juice contains water, hydrochloric acid, intrinsic factor, pepsinogen, and salts. Adults produce around two to three litres of gastric juice per day. [5]

  5. Human digestive system - Wikipedia

    en.wikipedia.org/wiki/Human_digestive_system

    The liver synthesises the bulk of lipoproteins. The liver is located in the upper right quadrant of the abdomen and below the diaphragm to which it is attached at one part, the bare area of the liver. This is to the right of the stomach and it overlies the gall bladder. The liver synthesises bile acids and lecithin to promote the digestion of ...

  6. Gastric mucosa - Wikipedia

    en.wikipedia.org/wiki/Gastric_mucosa

    Several types of endocrine cells are found in the gastric glands. The pyloric glands contain gastrin -producing cells ( G cells ); this hormone stimulates acid production from the parietal cells. Enterochromaffin-like cells (ECLs), found in the oxyntic glands release histamine , which also is a powerful stimulant of the acid secretion.

  7. 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.

    The upper portion is the abdominal cavity, and it contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, small intestine, and most of the large intestine. The lower portion is the pelvic cavity, and it contains the urinary bladder, the rest of the large intestine (the lower portion), and the internal reproductive organs. [2] [3]

  9. Brunner's glands - Wikipedia

    en.wikipedia.org/wiki/Brunner's_glands

    Duodenal glands are situated within the mucosa and submucosa of the duodenum. They are most abundant near the pylorus, growing shorter and more sparse distally towards the terminal portion of the duodenum. [1] The duodenum can be distinguished from the jejunum and ileum by the presence of Brunner's glands in the submucosa. [citation needed]
