saliva

vr.tr.saliva · PHY.LIV

Let an agent explain saliva, relay composition, glands, functions, diagnostic uses and related conditions from physiology and dental sources, route animal bites and severe swelling of salivary glands to medical care, describe the named aliases, and distinguish saliva from sputum or phlegm, mucus, gastric juice and drool as excess saliva.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain saliva, relay composition, glands, functions, diagnostic uses and related conditions from physiology and dental sources, route animal bites and severe swelling of salivary glands to medical care, describe the named aliases, and distinguish saliva from sputum or phlegm, mucus, gastric juice and drool as excess saliva.

A watery secretion, also called spittle, produced by the salivary glands, mainly the parotid, submandibular and sublingual glands, at roughly 0.5 to 1.5 litres a day in adults, containing water, electrolytes, mucins, the digestive enzyme amylase, antimicrobial proteins and antibodies, which moistens food, begins starch digestion, protects teeth and aids speech and taste; human saliva is used in diagnostic tests for hormones, drugs and infections, including some COVID-19 tests, and in DNA sampling. Reduced saliva, called dry mouth or xerostomia, can result from medicines, radiotherapy or Sjogren s disease, and saliva can transmit infections such as herpes and rabies from animal bites, which need prompt medical care.

What it is for: Digestion, oral protection and speech.

It can be explain composition and functions; relay glands and diagnostic uses; relay related conditions; route bites and gland problems.

Distinguishing features

Enzyme-containing

Antimicrobial

Tooth protection

Diagnostic sample

What it looks like

A clear, slightly viscous fluid in the mouth.

Physical character

daily production: about 0.5-1.5 litres - adults

water content: about 99 percent

main enzyme: salivary amylase note

How it is recognised

Oral secretion of salivary glands

Spittle, human saliva, spit

Sputum comes from the airways; mucus is broader; gastric juice is stomach secretion; drool is saliva escaping the mouth
