human digestive system
Enable an AI agent to recognise a human digestive system, assess its documented digestive capabilities and constraints, and identify observations or interventions that require authorised clinical judgment.
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 a human digestive system, assess its documented digestive capabilities and constraints, and identify observations or interventions that require authorised clinical judgment.
It can be Map the person's digestive anatomy and trace routes for intake, secretions, transit and output.; Record and compare digestive symptoms, output and function measurements with their methods and timing.; Relate documented organ or segment limitations to the digestive capabilities they may constrain.; Identify missing or conflicting evidence before making a digestive-state judgment.; Check proposed feeding, sampling or device-related actions against recorded anatomy, clinical restrictions and authorisation.; Flag observations for clinical review using an explicitly adopted escalation protocol..
Distinguishing features
A candidate represents the coordinated tract and accessory digestive contributions; a stomach, liver or intestine alone is a component rather than the whole system.
A candidate includes accessory-organ contributions as well as the alimentary tract; a gastrointestinal-tract-only model has a narrower boundary.
Human attribution is established through the associated person or specimen provenance; a generic vertebrate digestive description does not establish this registry identity.
Microorganisms and luminal contents are recorded as interacting communities or contents, not as human organs defining the system's identity.
Resection, bypass, stoma or absent organs are represented as variants of the person's digestive system rather than automatically disqualifying it as an instance.
Scope
+ The alimentary tract from mouth through pharynx, oesophagus, stomach and intestines to anus, with digestive roles distinguished from shared functions.
+ Salivary glands, liver, gallbladder and pancreas insofar as they contribute to digestion.
+ Ingestion, swallowing, transit, secretion, digestion, absorption and defecation.
+ Mucosal integrity, digestive symptoms and documented functional limitations.
+ Consequences of congenital variation, disease, surgery and digestive support devices for system function.
+ Interfaces through which microbes, circulation, immune activity and neural regulation affect digestion.
- Whole-person health, nutritional requirements and dietary planning as independently managed subjects.
- The respiratory system and its airway functions, including the shared pharyngeal interface.
- The complete endocrine, nervous, immune and cardiovascular systems.
- The gut microbial ecosystem as an independently characterised community.
- Detailed disease models, pharmaceutical products and clinical treatment protocols.
- Non-digestive liver and pancreatic functions except where they constrain digestive assessment or action.
Characteristics
- Human host association
- Associated person or human specimen, with provenance and privacy-appropriate identifier Establishes whose system is represented and whether observations concern a living person, a specimen or another representation.
- Digestive anatomy configuration
- Present, absent, resected, bypassed, reconstructed or unknown for each relevant segment and accessory organ Determines which digestive pathways and capabilities can reasonably be assessed.
- Luminal continuity and outlets
- Connections between tract segments, anastomoses, feeding access points, stomas and other documented communications Identifies the actual routes available for intake, transit and elimination.
- Swallowing capability
- Documented capability and limitations by intake consistency, assessment method and date; unassessed permitted Constrains oral intake and identifies when specialist assessment is needed.
- Segment transit time
- Minutes or hours, with segment, method, test conditions and applicable reference interval Supports assessment of propulsion without treating all transit tests as interchangeable.
- Digestive secretion status
- Assessed, impaired, supported or unknown by secretion type, with supporting evidence Separates digestive processing limitations from anatomical continuity and transit.
- Absorptive capability
- Adequate for assessed function, suspected impairment, confirmed impairment or unknown; specify substance and evidence Avoids treating absorption as one universal capability or inferring it from intake alone.
- Bowel and stoma output
- Events/day, mL/day or g/day as applicable, with outlet, collection interval and stool-form description Makes elimination and output changes comparable within an appropriate observation context.
- Digestive symptom profile
- Symptom type, location, onset, frequency, severity, triggers and patient-reported impact Preserves the experience and timing of dysfunction without equating a symptom with a diagnosis.
- Mucosal and wall integrity
- Documented findings by site and method, including unknown or incompletely examined regions Distinguishes observed tissue conditions from assumptions based on symptoms.

Digestive anatomy and continuity Establishes which digestive structures belong to the instance and how they connect.
Digestive capability depends on the actual tract and accessory connections, including altered anatomy.
Tract segments and shared boundaries
Identifies alimentary segments and distinguishes digestive roles at shared anatomical interfaces.
Instance-specific alimentary path
Record the documented mouth-to-outlet pathway, including uncertainty about segment presence or continuity.
- Which alimentary segments are present, and what evidence establishes their continuity? definition
- Which oral and pharyngeal observations concern digestive function, and which belong to dental, speech or respiratory models? boundary
Accessory connections and reconstruction
Represents digestive gland connections and pathways changed by development, surgery or devices.
Secretory and altered route map
Record where digestive secretions enter the tract and how resections, bypasses, anastomoses or stomas change routes.
- Which salivary, biliary and pancreatic drainage routes are documented as connected to the tract? definition
- Which operative reports, imaging findings or device records establish reconstructed routes and their current status? provenance
Intake, swallowing and transit Describes entry of material and its propulsion through the digestive tract.
An anatomically connected tract does not by itself establish usable intake or effective transit.
Oral processing and swallowing
Captures digestive entry capabilities and the swallowing interface with airway protection.
Documented intake capability
Record chewing and swallowing observations, assessed consistencies and current intake restrictions.
- What assessment documents chewing and swallowing capability for the relevant food or fluid consistency? provenance
- What current clinical instructions govern oral intake or require swallowing reassessment? action
Propulsion and passage
Distinguishes movement of contents from anatomical passage and suspected mechanical barriers.
Segment-specific transit evidence
Record evidence about oesophageal passage, gastric emptying and intestinal transit without inferring a cause from symptoms alone.
- Which segment's passage or transit was assessed, using what method and conditions? measurement
- What evidence supports distinguishing a propulsion limitation from a mechanical passage limitation? provenance
Secretions and digestive processing Represents the contributions that prepare luminal contents for absorption.
Digestive processing can be constrained by gland function or secretion delivery even when food passes through the tract.
Tract secretions
Records relevant salivary, gastric and intestinal secretion observations.
Local secretory function
Represent secretion-related evidence by location and substance, distinguishing direct tests from indirect indicators.
- Which secretion or luminal property was measured, at what site and under what intake or medication conditions? measurement
- Does the evidence directly assess secretion, or is it an indirect indicator whose interpretation needs qualification? provenance
Biliary and pancreatic contributions
Separates accessory-organ digestive output from its delivery into the tract.
Accessory digestive output and delivery
Record evidence concerning bile delivery and exocrine pancreatic contribution, together with prescribed digestive support.
- What evidence distinguishes reduced digestive output from impaired delivery through the relevant ducts or reconstructed route? provenance
- Which observations describe digestive contributions, and which require linked hepatic or endocrine models? boundary
- What prescribed enzyme or other digestive support must be considered when interpreting current function? action
Absorption and elimination Represents uptake from the digestive lumen and removal of residual contents.
A useful state assessment must distinguish intake, uptake and output rather than substituting one for another.
Nutrient, water and electrolyte uptake
Captures substance-specific evidence about absorption and the limits of indirect indicators.
Supported absorptive capability
Record the basis for claims about absorption, accounting for anatomy, intake and support.
- Which nutrient, fluid or electrolyte uptake capability is being assessed, and what test or observation supports the assessment? measurement
- Which whole-person nutritional or laboratory findings require a linked model before they can be attributed to digestive absorption? boundary
Defecation, continence and stoma output
Describes the route, pattern and control of digestive output.
Outlet-specific elimination pattern
Record bowel movements or stoma output relative to the person's anatomy and documented baseline.
- What are the frequency, amount where measured, consistency and route of output over a stated interval? measurement
- What difficulty, urgency, leakage or assistance accompanies elimination, and how does it differ from the documented baseline? measurement
Tissue integrity and regulatory interfaces Captures digestive tissue condition and interactions that influence its function.
The system includes living barriers and regulated activity whose state cannot be described by plumbing and throughput alone.
Mucosa, wall and local tissue state
Anchors tissue-state descriptions to specific sites, methods and examination coverage.
Localised integrity evidence
Record observed tissue changes and examination limits without converting unexplored regions into normal findings.
- Which digestive site and tissue depth were assessed by examination, endoscopy, imaging or histology? provenance
- What tissue condition was documented, and which regions remain unexamined or inconclusive? measurement
Microbial, neural, immune and circulatory links
Records relevant interactions while maintaining boundaries with neighbouring system models.
Evidenced digestive interface effects
Link microbial observations, regulatory influences and perfusion findings to digestive effects only to the extent supported.
- Which linked microbial, neural, immune or circulatory observation is relevant to the digestive capability being assessed? boundary
- What evidence supports the proposed digestive effect, and is that relationship established, suspected or unresolved? provenance
Digestive assessment and action constraints Combines symptoms and examination context with the constraints governing digestive actions.
Agents need to preserve uncertainty and recognise when an action depends on clinical instructions, altered anatomy or additional assessment.
Symptoms, course and assessment context
Places digestive observations in time and relates them to intake, medications and procedures.
Interpretable digestive state record
Separate reported symptoms, observed signs, test results and clinician interpretations while retaining their temporal relationships.
- When did each symptom or finding occur relative to meals, bowel output, medication changes and digestive procedures? measurement
- Who reported or interpreted each observation, and what uncertainty or disagreement remains? provenance
Feeding access, procedures and escalation
Connects proposed digestive actions to documented access, restrictions and clinical responsibility.
Authorised digestive action envelope
Record the prerequisites for feeding, sampling, access-device use and referral without deriving treatment permission from the model itself.
- What current orders, anatomical information and device-status checks govern the proposed feeding, sampling or access-related action? action
- Which adopted clinical protocol defines escalation criteria, and who is responsible for evaluating triggered concerns? action
What the second pass must settle
- Does an existing Vercy world model already own this concept, and which neighbouring registry entries should be linked rather than duplicated?
- Which anatomical terminology and boundary conventions should govern shared oral and pharyngeal structures and the digestive roles of the liver and pancreas?
- Which validated measures and reference intervals are appropriate across age groups, altered anatomy, feeding routes and assessment methods?
- What evidence is sufficient to represent digestive effects of microbial findings without implying an unsupported universal healthy microbiome?
- Which clinical protocols, jurisdictions and responsible roles should determine action restrictions and escalation criteria for intended deployments?
