Let an agent explain mucus and its functions in neutral clinical and biological terms, relay what changes in mucus indicate in general terms from clinical sources, describe mucus in other animals, and route personal symptoms to clinicians.

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 mucus and its functions in neutral clinical and biological terms, relay what changes in mucus indicate in general terms from clinical sources, describe mucus in other animals, and route personal symptoms to clinicians.

A slippery secretion of mucous membranes and glands, composed of water, mucin glycoproteins, salts, antibodies and cells, that lines and protects the respiratory, digestive and reproductive tracts and other surfaces by trapping particles and microbes and keeping tissues moist; mucus includes nasal mucus, sputum coughed from the airways, cervical mucus that changes through the menstrual cycle, and the slime coat of fish and amphibians.

What it is for: Protecting and lubricating body surfaces.

It can be explain composition and functions; relay clinical significance in general terms; describe mucus in other animals; route personal symptoms to clinicians.

Distinguishing features

Mucin gel

Barrier and clearance

Changes with infection and hormones

Present across animals

What it looks like

A clear to coloured viscous fluid on membranes; dried nasal mucus forms crusts.

Physical character

daily production in the airways and nose: about 1 litre - estimates

water content: about 95 percent

How it is recognised

Mucin-rich secretion of membranes

Nasal, airway, cervical and other kinds

Saliva and tears are related fluids; pus is an inflammatory exudate

What the second pass must settle

  • Should sputum and cervical mucus be separate entries?
  • How should clinical guidelines be linked?
  • The registry entry has merged aliases naming kinds and animal forms; should they be split off?
