AnatomicalSystem

AnatomicalSystem sits beside AnatomicalStructure under MedicalEntity. Where AnatomicalStructure is a single organ, bone, or muscle, AnatomicalSystem is the collaborating group: the cardiovascular system, the nervous system, the endocrine system.

Direct properties (5)

comprisedOf: AnatomicalStructure or AnatomicalSystem — component members (heart + vessels, hypothalamus + pituitary + adrenals).
relatedStructure: AnatomicalStructure — a structure associated with but not part of the system.
associatedPathophysiology: Text — what goes wrong when the system fails (hypertension, arrhythmia, thromboembolism for cardiovascular).
relatedCondition: MedicalCondition — diseases that affect the system.
relatedTherapy: MedicalTherapy — therapies targeting the system.

Common AnatomicalSystem mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.

01
AnatomicalSystem used for a single organ
Wrong
```
"@type": "AnatomicalSystem", "name": "Heart"
```
Right
```
"@type": "AnatomicalStructure" for a single organ; "AnatomicalSystem" for the collaborating group
```
An organ is a structure; a system is a collection of structures that work together. Cardiovascular system = heart + vessels, not just heart.
02
comprisedOf as a string
Wrong
```
"comprisedOf": "Heart, arteries, veins"
```
Right
```
Array of AnatomicalStructure / AnatomicalSystem nodes
```
Free text hides the component relationships crawlers and medical knowledge graphs walk through.
03
relatedCondition and associatedPathophysiology both filled with the same diseases
Wrong
```
Duplicating disease names in both fields
```
Right
```
associatedPathophysiology is free text describing mechanisms and manifestations; relatedCondition points to MedicalCondition entities
```
Pathophysiology = the story of what fails; relatedCondition = the structured link to the named disease entity. They complement rather than duplicate.
