Answer 1

White blood cells-

- White blood cells or WBCs or leukocytes is the most important factor of immune system.

- WBCs are divided into 5 classes depending upon their structure and function, these are neutrophils, eosinophils, basophils, lymphocytes and monocytes.

1) Neutrophils-

- It is produced in bone marrow and account 50-70% of total WBCs.

- These are abundant in nature.

- Neutrophils play important role in bacterial and fungal infection.

2) Eosinophils-

- These are 1-4% in the bloodstream.

- These play important role in parasitic infections and also in some allergic reactions.

3) Basophils-

- These are approximately 1-2% of WBCs in the bloodstream.

- It plays important role in the allergic reactions as it posses surface receptor for binding the antibody.

4) Lymphocytes-

- These are second most abundant type of WBCs as it accounts 20-40%.

- These are present in the lymph nodes, spleen, lymphatic tissues and the bloodstream.

- There are two types of lymphocytes T cells and B cells.

- The main function of these is to activate immune system and produces antibody.

5) Monocytes-

- These are largest type leukocyte and account 1-10% of total WBCs in the bloodstream.

- It plays important role in the infections
