The basic functional unit of the liver is the hepatic lobule, which consists of portal triads (hepatic arteriole, portal venule, bile duct, lymphatics and branch of the vagal nerve) at the periphery that surround a central vein (Fig.
LCV is defined by the following five criteria proposed by the American College of Rheumatology (7): 1) age > 16 at disease onset, 2) history of taking a medication at onset that may have been a precipitating factor, 3) the presence of palpable purpura, 4) the presence of maculopapular rash, and 5) a biopsy demonstrating granulocytes around an arteriole or a venule (LCV).

In this cryobiopsy specimen that has well-expanded airspaces, a low-power view shows a cellular infiltrate (A, arrow) that on high power is composed of only a few layers of lymphocytes surrounding a venule (B).
Vascular parameters such as venule dilation and larger retinal arteriolar calibre [9, 10], changes to the vasculature shapes and arteriolar branching angle, increased tortuosity [11-13], and Fractal Dimension (FD) of the retinal vascular network [14-16] are associated with DR.
Each appendage has 1 or 2 arterioles and a venule on its vascular stalk (1).
Veins, beginning with the postcapillary venule, collect blood from the microvascular bed and carry it away.
6) The edema induced by SP is primarily due to increased vascular permeability mediated through its action on NK-1 receptors situated on Post-capillary venule endothelial cells.
Higher magnification identified a parasite (a hydatid protoscolex) within a hepatic venule (Figures 4&5) and a diagnosis of hydatid disease (Echinococcus granulosus) was made.
It is probable that aquaporin-1 (AQ1), plentiful in high endothelium venules at the arteriole-venule junctions in lymph nodes, plays an important part (9,10).
9) Due to the relative high pressure kon the arterial side of the circulation, this blood mixture contains a relatively greater proportion of blood from the arteriole side of the capillary bed than from the venule side; and, thus, a "capillary-blood" sample obtained by skin puncture approximates closer to arterial blood than venous blood.
