ANATOMY

Detailed explanation-1: -B lymphocytes produce antibodies-proteins (gamma globulins) that recognize foreign substances (antigen) and attach themselves to them. B lymphocytes (or B cells) are each programmed to make one specific antibody.

Detailed explanation-2: -Immunoglobulins (Igs) are antigen-binding proteins produced by B cells. Igs contain two identical heavy (H) chains and two identical light (L) chains.

Detailed explanation-3: -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-4: -In addition to IgM, B1 B cells also produce polyreactive IgA antibodies that contribute to mucosal immunity along with IgA secreted by FO B cells (8).

Detailed explanation-5: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.
