artery
a blood vessel that carries blood from the heart to the body
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
Enable an AI agent to recognise an artery, record evidence about its structure and blood delivery, judge uncertainty in its condition, and identify actions requiring clinical assessment.
a blood vessel that carries blood from the heart to the body
It can be Locate and distinguish an artery or segment using anatomical landmarks and vascular connections.; Attach imaging, physiological measurements and interpretations to the exact observed segment.; Compare lumen, wall and flow observations across time while checking measurement comparability.; Trace downstream territories and documented alternative arterial routes when evaluating a local abnormality.; Flag uncertain or concerning observations for qualified clinical review using an explicitly identified assessment framework.; Record proposed or completed interventions and their prerequisites without treating model completeness as permission to intervene..
Distinguishing features
Identify the vessel through anatomical continuity with the arterial outflow pathway from the heart; an unusual or reversed flow observation alone must not change its anatomical identity.
Distinguish arteries from veins by their position in the circulation rather than oxygen content; pulmonary arteries must remain representable.
Distinguish a named artery from a branch or arbitrary segment by explicit proximal and distal landmarks.
Distinguish a native artery from a graft or prosthetic conduit by recording the origin and material of the vessel wall.
At the artery-arteriole boundary, require an explicit anatomical or terminology convention rather than assuming one universal diameter cutoff.
Scope

+ Observed blood flow, pressure and patency under stated conditions
+ Local abnormalities, implanted devices and previous interventions
- The heart's pumping function and cardiac disease
- Veins, capillaries and the microcirculation as independently modelled vessels
- Blood composition, coagulation disorders and systemic disease
- Whole-organ function and downstream tissue injury
- Clinical procedures, medications and implanted devices as independent entities
Characteristics
- Anatomical designation
- Preferred anatomical name, terminology identifier, aliases and laterality Prevents observations from being assigned to the wrong artery or side.
- Arterial circuit
- Systemic, pulmonary, other explicitly described circuit, or unresolved Establishes the context for interpreting connections, pressure and blood delivery.
- Segment boundaries
- Proximal and distal anatomical landmarks with parent-vessel reference Makes measurements and abnormalities comparable across observations.
- Branch and territory connections
- Upstream artery, downstream branches, anastomoses and supplied territories Connects a local arterial change to potentially affected blood-delivery pathways.
- Lumen dimensions
- Diameter in mm or cross-sectional area in mm², with location, method and acquisition phase Supports assessment of narrowing, dilation and change over time.
- Wall observations
- Observed wall features, location, extent, method and interpretive confidence Separates directly observed wall changes from inferred diagnoses.
- Patency
- Patent, partially obstructed, occluded, indeterminate or not assessed, with time and evidence Records whether a blood-flow pathway is demonstrably open.
- Blood-flow observation
- Velocity in cm/s, volume flow in mL/min, direction and waveform where available Describes blood movement without treating velocity alone as delivered blood volume.
- Arterial pressure
- mmHg, with measurement site, method, time and physiological conditions Prevents a pressure measured elsewhere from being mistaken for local arterial pressure.
- Intervention relationship
- Linked procedure or device, treated segment, date and current observed status Preserves the context needed to interpret altered anatomy and later observations.

Arterial identity and territory Establishes which artery is represented and where it sits in the circulation.
Arterial identity depends on anatomical continuity and branching context, not oxygen content or a single flow observation.
Anatomical identification
Resolves the vessel's designation, circuit and native-vessel identity.
Identified arterial entity
Record the evidence supporting identification as a particular native artery, including anatomical variants and unresolved naming differences.
- What anatomical name, laterality and arterial circuit identify this vessel? definition
- Which imaging, operative observation or anatomical record establishes its continuity with the arterial circulation? provenance
Segment and supply boundaries
Defines the represented extent and its connections to branches and territories.
Bounded segment and connections
Record proximal and distal landmarks, branch origins, supplied territories and documented anastomotic connections.
- Which landmarks delimit this artery or segment, and which branch origins fall within it? boundary
- Which downstream territories and alternative arterial connections are documented, and by what evidence? provenance
Arterial lumen and course Records the dimensions and spatial course of the blood-carrying channel.
Narrowing, dilation and tortuosity need location-specific geometry and explicit measurement conventions.
Lumen calibre
Captures lumen size and local variation along the segment.
Local lumen dimensions
Record measured diameters or areas, their positions and the reference used for any reported narrowing or dilation.
- What lumen diameter or area was measured, at which location, imaging plane and acquisition phase? measurement
- If narrowing or dilation is reported, which reference segment and calculation convention were used? measurement
Course and spatial relations
Describes the artery's route and relationships relevant to compression or access.
Arterial route and deformation
Record course, tortuosity, focal angulation and relationships to adjacent structures, distinguishing persistent anatomy from position-dependent observations.
- Where does the artery bend, deviate or pass through a potentially constraining anatomical space? boundary
- Do observed calibre or course changes depend on posture, movement or another recorded acquisition condition? measurement
Arterial wall and local lesions Records wall observations and local abnormalities affecting the wall or lumen.
An open lumen does not fully describe arterial condition; wall integrity and lesion extent require separate evidence.
Wall composition and integrity
Captures visible wall features and evidence about structural continuity.
Observed wall condition
Record wall thickening, plaque, calcification or suspected disruption as supported observations, with diagnostic interpretations separately attributed.
- Which wall features are directly visible, where are they located and what method demonstrated them? provenance
- What evidence supports or leaves unresolved a suspected separation, breach or other loss of wall integrity? measurement
Lesion extent and evolution
Localises abnormalities and preserves evidence of change.
Bounded arterial abnormality
Record each suspected or established lesion's longitudinal extent, branch involvement, interpretation and comparison with previous observations.
- What are the lesion's proximal and distal limits, and does it involve branch origins or adjacent segments? boundary
- What change is demonstrated by comparable observations, and what apparent change could reflect measurement differences? measurement
Arterial flow and delivery Captures patency, local haemodynamics and evidence connecting them to downstream blood delivery.
Anatomical appearance, observed flow and adequacy of tissue supply are related assessments that require distinct evidence.
Patency and haemodynamics
Records whether blood passage is demonstrated and under which physiological conditions.
Observed arterial flow state
Record patency, flow direction, velocity or volume flow, waveform and available local pressure with method and time.
- What evidence establishes patency or obstruction, and could absent detected flow reflect a limitation of the observation? measurement
- What flow and pressure measurements are available, and under what rest, exertion or other physiological conditions were they acquired? measurement
Downstream delivery context
Links arterial observations to separate evidence about supplied territories and collateral routes.
Supported delivery assessment
Record the evidence connecting this artery's condition to downstream delivery, without assuming that visible patency establishes adequate tissue perfusion.
- Which independent observations of downstream perfusion support an assessment of this artery's contribution to blood delivery? provenance
- Which collateral routes are anatomically documented, and which have evidence of functional flow? measurement
Arterial intervention and follow-up Connects altered arterial anatomy and current evidence to reviewable action decisions.
Prior treatment changes how an artery is interpreted, while proposed actions require vessel-specific evidence and clinical authority.
Treated arterial anatomy
Records the relationship between the native artery, treatment sites and linked devices or conduits.
Intervention site and current status
Locate previous repairs, access sites, anastomoses and implanted devices relative to native segments and branches.
- Which procedures or devices have affected this artery, at what sites and on what dates? provenance
- Where are the boundaries between native artery, repaired tissue, implanted device and any separate graft? boundary
Assessment and action prerequisites
Records the basis and unresolved prerequisites for further assessment or intervention.
Artery-specific action assessment
Record the clinical question, supporting arterial observations, missing evidence and responsible decision-maker for proposed monitoring, investigation or treatment.
- What artery-specific uncertainty or documented change is the proposed action intended to resolve or address? action
- Which anatomical, haemodynamic and clinical prerequisites must the responsible clinician establish before the proposed action can proceed? action
- Which named assessment framework and evidence support the proposed follow-up or escalation? provenance
What the second pass must settle
- Does the registry intend artery to include pulmonary and fetal arterial circuits despite its definition referring to blood carried to the body?
- What registry convention separates arteries from arterioles and determines when a branch or segment merits its own model instance?
- Which vessel-specific measurement conventions and reference ranges should govern assessments of narrowing, dilation and haemodynamic significance?
- How should repaired arteries, graft replacements and mixed native-prosthetic pathways retain identity across interventions?
- Which validated clinical frameworks should govern escalation and follow-up for each arterial territory, population and care setting?
