- 12 body systems (e.g. Skeletal, Muscular, Cardiovascular, Nervous, Digestive)
- 20 body regions (e.g. Head, Thorax, Upper Arm, Abdomen)
- 9 entity types: organ, muscle, bone, nerve, vessel, gland, ligament, tendon, joint
- Hierarchical parent-child organ relationships (e.g. Heart > Left Ventricle)
- Directional entity relationships: connects_to, innervates, supplies_blood, drains, is_part_of
- External IDs: FMA ID (Foundational Model of Anatomy), Wikidata QID, UBERON ID
- Clinical significance and function descriptions
- Watercolor anatomy illustrations
- Entity comparisons (N-squared)
- Glossary terms across anatomy categories
- Guides in themed series
- Interactive anatomy tools

## URL Patterns
- Append `.md` to any URL for plain-text markdown format.
- i18n: URL prefix `/{lang}` for non-English (ko, ja, zh-hans, es, fr, de, pt, ru, vi, tr, ar, hi, th, id).
- `/structures/` — Anatomical structures list (filterable by system, region, type) (e.g. `/structures/`)
- `/structure/{slug}/` — Structure detail with function, clinical significance, relations (e.g. `/structure/heart/`)
- `/systems/` — Body systems list (12 systems) (e.g. `/systems/`)
- `/system/{slug}/` — Body system detail with structures (e.g. `/system/cardiovascular/`)
- `/regions/` — Body regions list (20 regions) (e.g. `/regions/`)
- `/region/{slug}/` — Body region detail with structures (e.g. `/region/thorax/`)
- `/compare/` — Anatomy comparison tool (e.g. `/compare/`)
- `/compare/{slug1}/vs/{slug2}/` — Compare two structures (e.g. `/compare/heart/vs/lungs/`)
- `/glossary/` — Anatomy glossary (e.g. `/glossary/`)
- `/glossary/{slug}/` — Glossary term definition (e.g. `/glossary/anterior/`)
- `/guide/` — Anatomy guides (e.g. `/guide/`)
- `/guide/{slug}/` — Guide article (e.g. `/guide/cardiovascular-system-overview/`)
- `/tools/` — Interactive anatomy tools (e.g. `/tools/`)
- `/tools/{slug}/` — Tool page (e.g. `/tools/body-system-explorer/`)
- `/rankings/` — Anatomy rankings index (e.g. `/rankings/`)
- `/rankings/{metric}/` — Ranking by metric (e.g. `/rankings/most-structures-by-system/`)
- `/search/` — Search structures, glossary (e.g. `/search/?q=heart`)
