Hemodynamic Homeostasis

Mean arterial pressure (MAP) is owned by no single organ. This integrative volume closes the loop MAP = CVP + CO × SVR from the per-system seams, reads it through two molecular sensors (PIEZO1/2, NKCC2), and models its fast and slow defense — with essential hypertension as an integral-controller setpoint reset and chronic heart failure as a saddle-node basin collapse.

The reconstruction is grounded in real DNA. Each control node's identity is fixed by its master gene's nearest-neighbour stacking parameter γ, measured directly from the human promoter sequence (SantaLucia 1998) and validated against the locked DNA atlas bit-for-bit, never fitted: the slow volume integrator is the kidney node SIX2 (γ = 1.5556) and the renin–angiotensin node is REN (γ = 1.3634, measured on the same pipeline) [the γ values are code outputs on measured promoter sequence; γ sets each node’s switch threshold, identity is inherited from the DNA atlas, and reading an organ from it is interpretation]. On those grounded identities this volume closes the multi-organ loop, builds its molecular sensory layer, and reconstructs its setpoint and basin dynamics — part of the VP jamming branch → DNA blueprint.

Grounding and seams

The two pressure-control master genes are measured in-package from their cached promoter sequences (SIX2, REN), so their identities reproduce offline bit-for-bit. The remaining circuit-level inputs are taken from sibling packages under a single source of truth: cardiac output (cardiorespiratory), systemic vascular resistance / Windkessel tone (circulatory), kidney developmental order (DNA), and the FHN/R19 substrate (vendored). Carotid-body and cardiopulmonary afferents are cited where they enter the map, keeping one canonical home for each result.

How to read the grades

Every claim carries an explicit reproducibility grade, which is what makes the package auditable rather than rhetorical. code output marks a reproduced loop/curve shape or direction and a DNA-measured master-gene identity; [L] cited marks a cited molecular identity, gain or clinical mortality; [O] open marks an absolute first-principles scale that is deliberately left open, with its obstacle named in the irreproducibility ledger and the value separately anchored to clinical units in the calibration chapter (§12). The package asserts what it reproduces and is precise about what it cites and what it leaves open — the grading is a statement of rigor, not of doubt.
