4th most abundant WBC; kill parasitic worms; slightly phagocytic; role in allergy and asthma; abundance could mean allergic reaction
basophil
least abundant WBC; release histamine and other mediators of inflammation; contain anticoagulant
what are the agranulocytes

surrounds the testicle
penis
surrounds the urethra
