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 secretion and its mechanisms and modes, describe secretory organs and products, relate secretion to health at a general level, and support learning.

The process by which cells, glands and tissues produce and release substances such as hormones, enzymes, mucus, sweat, saliva and other body fluids for use elsewhere in the body or outside it, including internal secretion by endocrine glands into the blood, external secretion by exocrine glands through ducts, and modes such as merocrine, apocrine and holocrine secretion; secretion is a form of cellular transport studied in physiology and cell biology and disturbed in many diseases.

What it is for: Release of substances by cells and glands.

It can be explain mechanisms and modes; describe organs and products; relate to health generally; support learning.

Distinguishing features

Cellular transport

Endocrine and exocrine

Vesicle-mediated

Regulated

What it looks like

Not visible at cellular level; secreted fluids such as sweat and saliva.

How it is recognised

Substances released for use elsewhere

Endocrine or exocrine

Excretion removes waste rather than useful products
