Diapedesis is the process by which white blood cells move into tissue spaces from the interior of blood capillaries. It is the process of emigration of WBCs from the bloodstream. With the help of adhesion molecules, WBCs become attached to the endothelium of the blood vessels and squeeze between these cells. The adhesion molecules bind to the sugar moieties present on the surface of WBCs. Phagocytic WBCs such as neutrophils arrive at the site of infection by the process of diapedesis only.
Oxidation occurs when a reactant loses electrons during the reaction. Reduction occurs when a reactant gains electrons during the reaction. This often occurs when metals are reacted with acid.
