==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 '''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 [[Reabsorption and Secretion Along the Proximal Tubule - Anatomy & Physiology|proximal tubule]] thanks to the relatively weaker tight junctions which allow water and ions to pass paracellulary.
