The Diapedesis


Diapedesis is the penetration of erythrocytes through the intact wall of capillaries and small veins into surrounding tissues due to impaired vascular wall permeability . Diapedesis of erythrocytes is observed in physiological conditions (for example, during menstruation) and in many pathological conditions, for example, hemorrhage due to intoxication with arsenic, mercury and phosphorus salts, with uremia, jaundice and some infectious diseases (influenza, plague , anthrax ). Diapedesis of erythrocytes determines the clinical picture of hemorrhagic diathesis (see).
