In the Malpighian body of the spleen， glomerulus like blood capillary nets are
formed with the branches spread from the central artery.
Lymph capillaries run intricately with venous sinuses in the red pulp of the
spleen.
The lymph flow of the spleen is remakably increased by the rise of blood pressure
in the splenic vein. Much red blood cells are included in this lymph.
The spleen plays roles of blood reservoir， promotion of portal blood flow， and
filtration of blood by its continuous and rhythmical contraction.
