Copyright © 2009 Pearson Education, Inc. Functions of leukocytes (WBC) Lymphocytes – specific immune response (make antibodies and antibody- like proteins) Eosinophils – protect against parasites Basophils – contribute to allergic response Platelets – initiate blood clotting Neutrophils and Monocytes – protect against bacteria and fungi
