Expert Solution

Step 1 Introduction:

Lymphocytes are a type of white blood cell that functions as part of the immune system. Their various functions allow them to properly respond to foreign invaders in the body.

Step 2 Concept:

The three types of lymphocytes are

T-cell: They are produced in the thymus and are cell-mediated.

Cytotoxic T-cell: The main function is to kill virally infected cells, but they also kill cells with intracellular bacteria or tumorous cells.

Memory T-cell: They provide the immune system with memory against previously encountered antigens. Memory T cells may either be CD4+ or CD8+.

Helper T-cell: The roles of a Helper T-cell include activating other immune cells, releasing cytokines, and helping B cells to produce antibodies. They help to shape, activate, and regulate the adaptive immune response.
