Answer 1

ANSWER.

Formed element	Nucleus shape	Cytoplasm or granule color.	Functions	Prevalence.
Erythrocyte	No nucleus	Red color granules	Exchange of oxygen and carbodioxide to and from the tissues.	40 to 45% of whole blood.
Neutrophil	Multilobed nucleus	Purple granules	Protection against foreign bodies through phagocytosis.	0 to 50%
Eosinophil	Bilobed nucleus	Orange red granules.	Protect the body against foreign and allergic substances.	1 to 4%
Basophil	Bilobed nucleus.	Purple granules.	Granules contain histamine which release during inflammation. Heparin present in the granules help to prevent blood clotting.	0 to 1%
Lymphocyte	Round or slightly indented nucleus.	Light blue cytoplasm.	Produce antibodies and protect the body against various pathogens.	20 to 40%
Monocyte	Kidney shaped nucleus.	Muddy blue cytoplasm.	Monocytes enter into the tissues known as macrophages which give protection against pathogens.	2 to 8%
Platelet	No nucleus	Red purple granules.	Prevent blood clotting.	>1% of total WBCs.
