Quizplus · Accepted Answer

Diapedesis is the process by which leukocytes (white blood cells) move through the walls of small blood vessels (specifically, capillaries) and into the surrounding tissues. This process is important for the immune response, as it allows white blood cells to reach infected or damaged tissues in order to fight off infections or help with healing. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the movement of water molecules across a membrane from an area of low solute concentration to an area of high solute concentration. Filtration is the process by which fluid is moved along a pressure gradient, such as in the kidneys where blood is filtered to form urine.
