Poiseuille’s law assumes a Newtonian fluid. However, blood exhibits shear-thinning (non-Newtonian) due to RBC aggregation and deformation. The actual ΔP will be lower because apparent viscosity drops at low shear rates inside capillaries. Additionally, RBCs deform, reducing effective friction, so the true pressure drop may be ~20–30% below 375 Pa. [ \Delta P = \frac8 \eta L (v

Some of the key features of the 5th edition of "Physics for the Biological Sciences" include: reducing effective friction
