Diapedesis
The movement of the WBC through a capillary is called diapedesis. In very general terms it is also called extravasation
the passage of blood cells, esp. leukocytes, through the unruptured walls of the capillaries into the tissues.Leukocyte extravasation is the movement of leukocytes out of the circulatory system, 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.
Slow flow speed in the capillary increases the efficiency of diffusion. In addition, the thin wall of the capillary helps substances to pass through efficiently.
