Together, the arterioles, associated capillary network, and postcapillary venules form a functional unit called the microcirculatory or microvascular bed of that tissue.

The pre-exercise parameters (condition "pre-exercise") venous oxygen saturation (SO2), postcapillary venous filling pressures (rHb) and microcirculatory blood flow (flow) were measured at two distinct tissue depths (2 mm and 8 mm) after resting 10 minutes on the ergometer bicycle.
Increased permeability results mainly from actions of histamine on postcapillary venules, where histamine causes the endothelial cells to contract and separate at their boundaries (Goodman-Gilman 1990).

The measurement depth of the LDF reaches to the arterioles, capillaries, and postcapillary venules of the upper horizontal plexus but does not extend to the deep horizontal plexus [36].
Amazingly, he demonstrated that nothing happened in the capillaries but that there was separation of the endothelial cells in postcapillary venules, which was the pathogenesis of the vascular leak; this totally unexpected observation is widely regarded as one of the major discoveries in experimental vascular pathology.
Hemangiopericytoma is an uncommon hypervascular mesenchymal neoplasm originating from modified contractile smooth-muscle cells that surround capillaries and postcapillary venules, called pericytes of Zimmerman.
