Leukocyte extravasation

Movement of white blood cells out of blood vessels and towards the inflamed site

In immunology, leukocyte extravasation is the movement of leukocytes out of the circulatory system (extravasation) and towards the site of tissue damage or infection. This process forms part of the innate immune response, involving the recruitment of non-specific leukocytes. Monocytes also use this process in the absence of infection or tissue damage during their development into macrophages.
