a Effects of fluid filtration (J v) across capillaries on subglycocalyx albumin concentration. Albumin entering into the interstitium via a large pore (J s, solid arrow in black) diffuses backwards into the subglycocalyx space according to concentration gradients (i.e., upstream diffusion, dotted arrow in black). Fluid filtration across the endothelial glycocalyx (EG) layer dilutes albumin in the subglycocalyx space (i.e., downstream washout, dotted arrow in white). Cited from reference [17] with permission.
