MICROANATOMY

Detailed explanation-1: -B lymphocytes, also called B cells, create a type of protein called an antibody. These antibodies bind to pathogens or to foreign substances, such as toxins, to neutralize them. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection.

Detailed explanation-2: -The B Cells have the ability to transform into plasmocytes and are responsible for producing antibodies (Abs). Thus, humoral immunity depends on the B Cells while cell immunity depends on the T Cells.

Detailed explanation-3: -Through receptor molecules on their surfaces, lymphocytes are able to bind antigens (foreign substances or microorganisms that the host recognizes as “nonself”) and help remove them from the body. Each lymphocyte bears receptors that bind to a specific antigen.

Detailed explanation-4: -Lymphocyte activation occurs when lymphocytes (B cells or T cells) are triggered through antigen-specific receptors on their cell surface. This causes the cells to proliferate and differentiate into specialized effector lymphocytes.
