Answer to Question 1

ANS: A
Marginated granulocytes are granulocytes clinging to the sides of small venules. They freely exchange with granulocytes in the circulating pool but can readily move into tissue along a chemotactic gradient when needed.

Answer to Question 2

ANS: D
Each white cell plays a different primary role in defending the body against nonself agents. Granulocytes are the primary defense against bacteria; eosinophils kill parasites; and plasma cells, which are fully differentiated B cells, make antibodies.
