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).

    As a result, saliva allows some digestion to occur before the food reaches the stomach. [30] Taste: [31] Saliva acts as a solvent in which solid particles can dissolve and enter the taste buds through oral mucosa located on the tongue. These taste buds are found within foliate and circumvallate papillae, where minor salivary glands secrete ...

    Seromucous glands (mixed) secrete both protein and mucus. Examples include the salivary glands: although the parotid gland (saliva secretion 25%) is predominantly serous, the sublingual gland (saliva secretion 5%) mainly mucous gland, and the submandibular gland (saliva secretion 70%) is a mixed, mainly serous gland.

  5. Parotid gland - Wikipedia

    en.wikipedia.org/wiki/Parotid_gland

    The serous cell predominates in the parotid, making the gland secrete a mainly serous secretory product. [10] The parotid gland also secretes salivary alpha-amylase (sAA), which is the first step in the decomposition of starches during mastication. It is the main exocrine gland to secrete this.

  6. 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 .

  7. Submandibular gland - Wikipedia

    en.wikipedia.org/wiki/Submandibular_gland

    The secretory acinar cells of the submandibular gland have distinct functions. The mucous cells are the most active and therefore the major product of the submandibular glands is saliva which is mucoid in nature. Mucous cells secrete mucin which aids in the lubrication of the food bolus as it travels through the esophagus.

  9. Human digestive system - Wikipedia

    en.wikipedia.org/wiki/Human_digestive_system

    Saliva contains the digestive enzymes amylase, and lingual lipase, secreted by the salivary and serous glands on the tongue. Chewing, in which the food is mixed with saliva, begins the mechanical process of digestion. This produces a bolus which is swallowed down the esophagus to enter the stomach.
