Integration is not decoration — it is a deliberate method for making each unit reach outward into history, reading, and writing first, then into geography, ethics, data, and economics, so the human anatomy becomes something a student can think with rather than just recall. Memory is associative: a formula lashed to a discovery, a controversy, and a consequence is held by a dozen threads instead of one.
Every unit radiates the same structured set of connections off the science spine — three tiers plus a quantitative lane. This is what keeps the cross-domain work rigorous instead of random.
| Tier | What it carries |
|---|---|
| Core spokes always required | History, Reading, Writing. Every unit names who discovered the idea and what they got wrong first, gives a real text to read (primary source, biography, living book — not a textbook chapter), and asks for writing in the student’s own voice. These run in every unit, no exceptions. |
| Standard spokes where they fit | Geography (where in the world this matters — industry, resources, environment) and soft social studies (the ethical and policy stakes). Where a unit genuinely doesn’t carry these, we move them to the elective pool rather than fake a connection. |
| Elective spokes pick ~two of five | Data & quantitative · Ethics · Economics · Technology & engineering · Art & design. Additive depth, never a substitute for the core. Letting students choose feeds wonder and lets faster students go deeper. |
| Applied-math lane always present | Math is not a spoke — we use math, we are not a math program. Human Anatomy leans on math more than most sciences; every unit names the specific math the human anatomy actually requires, done inside the lab context. The per-unit lane is on Page 3. |
Integration is graded as its own strand, separate from the science-mastery criteria. A student can be Mastered on the human anatomy and only Approaching on integration, or the reverse — which keeps the science bar pure while still rewarding cross-domain depth.
Every unit has an anchor built the same way. Each row names the unit’s anatomical big idea and the real-world anchor that carries the History, Reading, and Writing core — a doorway, not a detour.
| Unit | Human Anatomy big idea | Integration anchor |
|---|---|---|
| 01 Cells, Tissues & Body Plan | The body is built from cells organized into four tissue types and nested levels of organization. | Cell theory from Hooke to Virchow — pair with The Immortal Life of Henrietta Lacks; one cell line reshapes medicine and consent. |
| 02 Skeletal & Muscular | Muscles pull on bones across joints to produce movement — the body as a system of levers. | Vesalius’s 1543 Fabrica overturning Galen — observation displaces authority (the worked example below). |
| 03 Cardiovascular | The heart is a double pump driving blood through one closed circuit. | Harvey’s De Motu Cordis (1628) proving circulation against Galen — the quantitative argument that blood must recirculate. |
| 04 Respiratory | Gas exchange moves oxygen into the blood and carbon dioxide out across the alveoli. | Priestley and Lavoisier finding respiration is a slow combustion — students measure lung volumes and plot the data. |
| 05 Nervous System & Senses | Neurons carry electrochemical signals; the nervous system senses, integrates, and responds. | Cajal and Golgi and the neuron doctrine (Nobel 1906) — pair with Sacks’s The Man Who Mistook His Wife for a Hat. |
| 06 Digestive & Urinary | The body breaks down food for fuel and filters the blood to hold its internal balance. | Beaumont’s window into St. Martin’s stomach — gastric digestion revealed, and the uneasy ethics of it. |
| 07 Endocrine & Reproductive | Hormones are chemical messengers that coordinate the body through feedback loops. | Banting and Best isolating insulin in 1921 — a fatal diagnosis becomes manageable; read the glucose curves. |
| 08 Immune & Integumentary | The body defends itself through physical barriers and specific, learned immunity. | Jenner’s 1796 smallpox inoculation and Metchnikoff’s phagocytes — how the body learns a threat. |
Big idea: muscles pull on bones across joints to make movement — a system of levers, never pushes. Anchor: for 1,300 years medicine trusted Galen, who dissected animals; in 1543 Vesalius’s Fabrica, drawn from his own human dissections, corrected him on hundreds of points. Question: students put a Galen claim next to the articulated skeleton and torso model, trace which muscles cross a joint, and reason out the lever. Connection back: this is the musculoskeletal lever system — and the observational method that founds all of anatomy, the same insistence on looking behind every specimen defense.
Math never drives a unit, but human anatomy uses it constantly — always anchored to the structure or measurement at the bench. Here is the quantitative skill each unit actually uses, done inside the lab context rather than as a parallel curriculum.
| Unit | Applied math (in the lab context) |
|---|---|
| 01 Cells, Tissues & Body Plan | Magnification and scale; surface-area-to-volume ratio; unit conversions (µm, mm). |
| 02 Skeletal & Muscular | Lever class and mechanical advantage; torque about a joint; range-of-motion angles. |
| 03 Cardiovascular | Cardiac output (CO = HR × SV); blood-pressure ratios; percent vessel stenosis. |
| 04 Respiratory | Lung volumes and capacities; minute ventilation (rate × tidal volume); partial pressures. |
| 05 Nervous System & Senses | Reaction time and nerve conduction velocity (distance ÷ time); stimulus–response timing. |
| 06 Digestive & Urinary | Basal metabolic rate and caloric math; renal clearance and filtration rate. |
| 07 Endocrine & Reproductive | Feedback set-points and dose–response; hormone half-life; reading blood-glucose curves. |
| 08 Immune & Integumentary | Antibody-titer dilution series; the rule of nines for burn area; herd-immunity thresholds. |
Students do the cardiac-output arithmetic inside the circulation lab, the lever mechanics inside the musculoskeletal dissection, the titer dilution inside the immunity investigation. The number always means something because it is attached to a result they produced — never a worksheet detached from the anatomy.
Integration is its own strand. Track each unit’s integration level across the year — Not Yet, Approaching, or Mastered — separate from the science-mastery rubric. Record demonstration tokens earned in the final column.
| Unit | Not Yet | Approaching | Mastered | Tokens |
|---|---|---|---|---|

A student who walks through all eight anchors finishes understanding that human anatomy is how humans learned to reshape matter, and that every formula on the page was once a discovery someone fought for — the version of the subject a student keeps.
