abdomen
Let an agent explain the abdomen as an anatomical region in humans, other vertebrates and arthropods, relay its regions, contents and terminology from reference sources, and route symptoms and clinical questions 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 the abdomen as an anatomical region in humans, other vertebrates and arthropods, relay its regions, contents and terminology from reference sources, and route symptoms and clinical questions to clinicians.
The part of the body between the thorax and the pelvis in vertebrates, containing the digestive organs, liver, spleen, kidneys and, in humans, bounded by the diaphragm above, the abdominal wall in front and sides, and the pelvis below; in arthropods the abdomen is the rear body segment behind the thorax.
What it is for: Housing and protecting the digestive and other organs.
It can be explain regions and contents; explain anatomical terminology; distinguish vertebrate and arthropod abdomens; route symptoms to clinicians.
Distinguishing features
Region between diaphragm and pelvis in humans
Muscular wall rather than bony cage
Contains peritoneal and retroperitoneal organs
Different meaning in arthropod anatomy
What it looks like
In humans the belly region between chest and pelvis; in insects the segmented rear body part.
Physical character
human abdominal regions: 9 regions - or four quadrants in clinical use
How it is recognised
Between thorax and pelvis in vertebrates
Contains the digestive organs
In arthropods the rear segment; the pelvis and chest are separate regions

What the second pass must settle

- The registry entry has merged aliases for body shapes and an insect structure; should they be split off?
