==Pressure in the Peritubular Capillaries==

The peritubular capillaries have a lower hydrostatic pressure and a higher protein osmotic pressure than the rest of the capillaries in the body.  This is largely thanks to the fact that the blood within them has had a substantial quantity of its plasma removed by the [[The Formation of the Filtrate by the Glomerular Apparatus- Anatomy & Physiology | Glomerulus]].  Resulting in a low concentration of solutes but a high concentration of protein.  These pressures however are not constant and changes in them affect reabsorption.  They have the biggest effect in the '''proximal tubule''' thanks to the relatively weaker tight junctions which allow water and ions to pass paracellulary.
