Answer to Question 1

ANS: D
Basophils have cytoplasmic granules that contain vasoactive amines (e.g., histamine) and an an-ticoagulant (heparin). Their function is similar to tissue mast cells. Neutrophils are the chief phagocytes of early inflammation. Eosinophils ingest antigen-antibody complexes and are in-duced by IgE-mediated hypersensitivity reactions to attack parasites. Monocytes do not have amines, and their job is to help fight infection.

Answer to Question 2

ANS: A
Neutrophils constitute about 40-60 of the total leukocyte count in adults. The eosinophils, which have large, coarse granules, constitute only 1-4 of the normal leukocyte count in adults. Basophils make up less than 1 of the leukocytes. Lymphocytes constitute approximately 36 of the total leukocyte count.
