  2. Saliva - Wikipedia

    en.wikipedia.org/wiki/Saliva

    Saliva on a baby's lips. Saliva (commonly referred to as spit or drool) is an extracellular fluid produced and secreted by salivary glands in the mouth.In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).

  3. Lingual lipase - Wikipedia

    en.wikipedia.org/wiki/Lingual_lipase

    Lingual lipase is a member of a family of digestive enzymes called triacylglycerol lipases, EC 3.1.1.3, that use the catalytic triad of aspartate, histidine, and serine to hydrolyze medium and long-chain triglycerides into partial glycerides and free fatty acids.

  4. Salivary gland - Wikipedia

    en.wikipedia.org/wiki/Salivary_gland

    The salivary glands in many vertebrates including mammals are exocrine glands that produce saliva through a system of ducts. Humans have three paired major salivary glands (parotid, submandibular, and sublingual), as well as hundreds of minor salivary glands. [1] Salivary glands can be classified as serous, mucous, or seromucous (mixed).

  5. Human digestive system - Wikipedia

    en.wikipedia.org/wiki/Human_digestive_system

    A peptide hormone, gastrin, produced by G cells in the gastric glands, stimulates the production of gastric juice which activates the digestive enzymes. Pepsinogen is a precursor enzyme produced by the gastric chief cells, and gastric acid activates this to the enzyme pepsin which begins the digestion of proteins. As these two chemicals would ...

  6. Von Ebner's gland - Wikipedia

    en.wikipedia.org/wiki/Von_Ebner's_gland

    Human Von Ebner's gland. Von Ebner's glands, also called Ebner's glands or gustatory glands, are exocrine glands found in the mouth. More specifically, they are serous salivary glands which reside adjacent to the moats surrounding the circumvallate and foliate papillae just anterior to the posterior third of the tongue in its submucosa, anterior to the terminal sulcus.

  7. Submandibular gland - Wikipedia

    en.wikipedia.org/wiki/Submandibular_gland

    Mucous cells secrete mucin which aids in the lubrication of the food bolus as it travels through the esophagus. In addition, the serous cells produce salivary amylase, which aids in the breakdown of starches in the mouth. The submandibular gland's highly active acini account for most of the salivary volume.

  8. Lipase - Wikipedia

    en.wikipedia.org/wiki/Lipase

    Hepatic lipase acts on the remaining lipids carried on lipoproteins in the blood to regenerate LDL (low density lipoprotein). – lipoprotein lipase: LPL or "LIPD" endothelium: Lipoprotein lipase functions in the blood to act on triacylglycerides carried on VLDL (very low density lipoprotein) so that cells can take up the freed fatty acids.

  9. Heterocrine gland - Wikipedia

    en.wikipedia.org/wiki/Heterocrine_gland

    Exocrine function: The primary role of salivary glands is to produce and secrete saliva into the oral cavity through ducts. This secretion is vital for various digestive processes, including moistening food to aid in swallowing , breaking down complex carbohydrates through the enzyme amylase , and providing lubrication for speech and mastication .
