Splenic Sinus

the wide venous capillaries following the arterial splenic capillaries. Have a fragmentary porous endothelium permeable to intact erythrocytes from the extravascular space of the red pulp, consisting of spindle-shaped phagocytosis-enabled →Retikulumzellen (bank cells) and transverse →Reticulinfasern. Its contractile walls can accelerate, slow or block the blood flow as needed.
