AP BIOLOGY

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.

Detailed explanation-2: -Thus, helper T cells regulate both the production of antibody by B cells and the isotype that determines the effector function of the antibody.

Detailed explanation-3: -FO B cells and MZ B cells. Most common type of B cell and, when not circulating through the blood, is found mainly in the lymphoid follicles of secondary lymphoid organs (SLOs). They are responsible for generating the majority of high-affinity antibodies during an infection.

Detailed explanation-4: -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-5: -B cell or B lymphocyte (bursa-derived cells) is a key player of the adaptive immune response that is responsible for humoral immunity in mammals. B-cell production in humans is a lifelong process that starts in the fetal liver intrauterine and bone marrow after birth. Their development is from hematopoietic stem cells.
