A comprehensive analytical solution of macromolecular transport within an artery
Mehrzad Khakpour,Kambiz Vafai +1 more
TL;DR: In this paper, the volume-averaged porous media equations are employed to solve for transport through the porous arterial layers, and the Staverman filtration coefficient is incorporated to account for selective permeability of each porous layer to macromolecules.

Filtration, diffusion and molecular sieving through peripheral capillary membranes; a contribution to the pore theory of capillary permeability.
TL;DR: Theoretical and experimental studies on the sieving of molecules by ultrafiltration through porous membranes indicate that an effective pore diameter of at least IOO A would be required to explain permeability of this magnitude.

Passage of Molecules Through Capillary Walls
TL;DR: A wealth of evidence supports the view that the exchange of materials through the walls of living capillaries takes place by physical processes which involve no expenditure of energy on the part of the capillary endothelial cells themselves.
