kPa (Myocardial Wall Stress) & mmHg (Pressure)
The application of solid and fluid mechanics principles to model heart chamber contraction, blood flow dynamics, and myocardial wall stress.
Wall Stress σ = (P × r) / (2 h) (Law of Laplace for Spheres)

Hounsfield Units (HU, Water = 0, Air = -1000, Bone = +1000)
A diagnostic medical imaging modality combining rotating X-ray tubes and digital detectors with filtered back-projection algorithms to produce 3D cross-sectional tissue images.
Hounsfield Unit HU = 1000 × (μ_tissue - μ_water) / (μ_water - μ_air)

pN·μm² (Bending Stiffness)
The study of the mechanical properties, viscoelasticity, and force generation of the intracellular filament network (actin, microtubules, intermediate filaments).
Flexural Rigidity EI = E_young × I_area_moment
