organ system
Let an agent explain organ systems and their classification, describe the major systems and their functions, relay how systems interact and how medicine is organised around them, and distinguish organ systems from organs and from functional groupings.
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 organ systems and their classification, describe the major systems and their functions, relay how systems interact and how medicine is organised around them, and distinguish organ systems from organs and from functional groupings.
A group of organs that work together to perform one or more related functions in the body, such as the digestive, circulatory, respiratory, nervous, endocrine, urinary or excretory, reproductive, musculoskeletal, integumentary, immune and lymphatic systems, with functional groupings such as the cardiopulmonary system, the exocrine system and the craniomandibular system and the older term vegetative apparatus for autonomic and visceral systems; organ systems are the highest level of organisation below the organism and the basis of anatomy and medical specialties.
What it is for: Organising bodily functions.
It can be explain the concept and classification; describe major systems; relay interactions; distinguish from organs and groupings.

What it looks like
Not a single object; diagrams of the body colour-coded by system.
Physical character
major human organ systems: about 11 count - by common classification
How it is recognised
Group of organs with related functions
Digestive, circulatory, nervous, endocrine, urinary and other systems
An organ is a single structure; a tissue is a level below; functional groupings such as cardiopulmonary combine systems

What the second pass must settle
- Should each major system be the primary linked entry?
- How should anatomical terminology be linked?
- The registry entry has merged aliases naming specific systems and older terms; should they be split off?
