Write the functions of the two types of lymphocytes in the defense mechanism of the body.

The lymphocytes mainly found in lymph and are responsible for producing the immune response.

Lymphocytes are of two types—

i. B-lymphocytes

ii. T-lymphocytes

B-lymphocytes

B-lymphocytes is also known as B-cells and they mature in the bone marrow.

They produce an army of protein in blood, known as antibodies in response to pathogens. They are involved in the antibody-mediated immunity(AMI) or humoral immunity.

T-lymphocytes

T-lymphocytes is also known as T-cells and they mature in the thymus gland.

They help B-cells(B-lymphocytes) to produce antibodies and are capable of destroying the cancer cell. They are involved in the cell-mediated immunity(CMI).
