ANATOMY

Detailed explanation-1: -B-cells are the type of cells that produce antibodies to fight bacteria and viruses. These antibodies are Y-shaped proteins that are specific to each pathogen and are able to lock onto the surface of an invading cell and mark it for destruction by other immune cells.

Detailed explanation-2: -An antibody is a protein produced by your immune system to attack and fight off these antigens.

Detailed explanation-3: -Immunoglobulins (Igs) are antigen-binding proteins produced by B cells. Igs contain two identical heavy (H) chains and two identical light (L) chains. Each H chain associates with an L chain to form an antigen-binding site so that each Ig is bivalent.

Detailed explanation-4: -B cells create antibodies. 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.
