Diapedesis
something
diapedesis
they squeeze through capillary walls in a process called diapedesis
neutrophils
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.
Diffusion ;)
By a process called "capillary" action.
diapedesis
Osmosis through the roots, then capillary action up the trunk and branches.
Capillary Action draws water and other fluids through small porous channels.
Capillary exchange is the process by which substances, such as oxygen and nutrients, are exchanged between the blood in capillaries and the surrounding tissues. This occurs through diffusion, facilitated diffusion, and active transport. The exchange is driven by a concentration gradient and the movement of substances across the capillary wall is regulated by small pores called fenestrations and by the presence of transport proteins.
