Alteration of zebrafish hematocrit in the capillary-pressure driven micro-channel at 27 °C. (A–C) The square of travel distance versus time scatter plot (asterisks) reveals the linear fitting based on the Newtonian fluid assumption (solid line, eq. (11) with n = 1). A = plasma, B = 13% hematocrit, C = whole blood. (D–F) The inverse of mean velocity versus travel distance scatter plot (square dots) supports the linear fitting based on the Newtonian fluid assumption (solid line, eq. (10) with n = 1). D = plasma, E = 13% haematocrit, F = whole blood. (G–I) Viscosity versus shear rate scatter plot (round dots) supports the fitted power law parameters m and n in eq. (1). The method was adopted from Kang et al.³². G = plasma, H = 13% haematocrit, I = whole blood.
