Quizplus · Accepted Answer

The pool of cells that is the first to arrive when extra granulocytes are needed in the tissues is those that are marginating. Margination is the process by which white blood cells move from the center of blood vessels to the periphery near the walls of blood vessels, where they can interact with and move into the tissues. This is the first step in the process of migration from the blood into the tissues in response to an infection or injury.
