Define the Lymphocytes

They are agranulocytes. The nucleus occupies approximately the entire cell. They vary in size from 6- 18 mm diameter; sometimes divide in small and large lymphocytes. Lymphocytes build up 30% to 40% of all leukocytes. Lymphocytes come in two categorizes: B cells (those that mature in bone marrow) and T-cells (those that mature in the thymus). Let us get to know them. B-cells, while stimulated, mature into plasma cells.

These are the cells which generate antibodies. A specific B cell is tuned to a particular germ, and when the germ is availabe in the body, the B-cell clones itself and generates millions of antibodies designed to eliminate the germ. T-cells, on the other hand, in fact bump up against cells and kill them. T-cells termed as Killer T-cells can detect cells in our body which are harboring viruses, and when it detects such type of a cell, it kills it. Two other types of T-cells, termed as Helper and Suppressor T-cells help sensitize killer T-cells and control the immune Response.
