Diapedesis
Diapedesis
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.
Filtration results when nutrients are moved through the capillary walls by hydrostatic pressure. Hydrostatic pressure in the capillaries is greater than the osmotic pressure so there is a net movement of fluid and/or solutes out of the capillaries.
intercellular clefts
neutrophils
Osmosis
Yes, the capillaries are the smallest kind of blood vessel, that facilitate the movement of substances (like oxygen and glucose) in and out of the blood through their very thin walls.
Diffusion ;)
