ANATOMY

Detailed explanation-1: -These are cell surface receptors that are attached to the plasma membrane. The B-Cells produce protein structures called antibodies. The B-cell receptors attach to free moving antigens. They bind to the foreign organism/pathogen and activate the Immune System.

Detailed explanation-2: -B cells have B cell receptors (BCRs) on their surface, which they use to bind to a specific protein. Once the B cells bind to this protein, called an antigen, they release antibodies that stick to the antigen and prevent it from harming the body. Then, the B cells secrete cytokines to attract other immune cells.

Detailed explanation-3: -Each B cell produces a single species of antibody, each with a unique antigen-binding site. When a naïve or memory B cell is activated by antigen (with the aid of a helper T cell), it proliferates and differentiates into an antibody-secreting effector cell.

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. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection.
