20)formed elements of blood refers to the corpuscles or blood cells such as RBC, WBC and platelets

21) whole blood refers to the total volume of blood including plasma and formed elements .

22) The main component of erythrocyte is haemoglobin. it helps to carry oxygen.

23) Phagocytosis is the process of bacterias and other antigens by the WBC especially neutrophils.

24) A white blood cell also called as leukocyte.

25) pyrogen , a substance produced by neutrophils causes fever.
