Explanation / Answer

3. diapedesis

(Diapedesis also called Leukocyte extravasation, is the movement of leukocytes out of the circulatory system towards the site of tissue damage or infection mainly in post-capillary venules where haemodynamic shear forces are minimised. Functions include phagocytosis of foreign particles, production of antibodies, secretion of inflammatory response triggers (histamine and heparin), and neutralization of histamine.).
