SKILL

What you will be able to do

• Describe the six major organ systems covered in this module (nervous, cardiovascular, respiratory, musculoskeletal, digestive, immune) in terms of their primary functions and their contributions to homeostasis.
• Explain how the body is organized hierarchically (cell → tissue → organ → organ system) and why each level of organization produces emergent properties that the level below cannot accomplish alone.
• Define homeostasis as the body’s self-organizing principle and identify how specific organ systems maintain it (e.g., respiratory system maintaining blood pH through CO2 regulation, cardiovascular system maintaining tissue oxygenation through cardiac output).
• Trace how dysfunction in one organ system propagates to others — given a primary disruption (chronic stress, respiratory failure, gut dysfunction), identify secondary effects across at least two other systems.
• Connect biomedical organ-system descriptions to alternative frameworks: TCM’s Zang-Fu functional systems, somatic awareness of the musculoskeletal-nervous system interface, and the biopsychosocial model’s integration of biological processes with psychological and social factors.
• Explain why “the body is a machine” is misleading and why “self-organizing system” is a more accurate frame for understanding health, disease, and treatment.

Prerequisites

• No formal prerequisites. The introductory curriculum provides the conceptual foundation.
• Familiarity with the foundational terms (cell, tissue, organ, neuron, receptor, homeostasis, inflammation) is helpful and can be acquired through the human body module’s term files.

Reference documents

• Introduction to the Human Body — the introductory lesson
• The Nervous System — neural integration and autonomic regulation
• The Cardiovascular System — transport and circulation
• The Respiratory System — gas exchange
• The Musculoskeletal System — structure and movement
• The Digestive System — nutrition, immunity, and the gut-brain axis
• The Immune System — defense and inflammation
• Zang-Fu (Organ-Function Systems) — TCM’s functional alternative to anatomical organ systems

Scope

This skill covers conceptual understanding of organ system integration. It does not cover:

• Clinical assessment of organ system function (physical examination, laboratory interpretation, imaging)
• Detailed histology or cellular biology
• Pathophysiology of specific diseases
• Surgical or procedural anatomy

Verification

You have this skill if you can: (1) describe each of the six major organ systems by function and homeostatic contribution; (2) given a primary disruption, trace its propagation across at least three organ systems; (3) explain why the digestive system is simultaneously a digestive, endocrine, immune, and nervous organ — and why this matters for understanding disease; and (4) articulate at least one way that TCM’s Zang-Fu framework captures functional integration that biomedicine’s organ-specific approach can obscure.
