Perfusion is actively modified by the smooth muscles of the small arteries (arterioles, which in turn are influenced by local metabolic, nervous and hormonal mechanisms as well as ions) in terms of adapting the driving pressure gradient and transmural pressure to local needs. Here also a part of the blood plasma water (possibly also parts of the plasma proteins) escapes through the capillary endothelia into the interstitium, in order to leave it again, after perfusion or diffusion, at the venous part of the capillaries and through lymph capillaries.
