PATHOLOGY

Detailed explanation-1: -Plasma cells: Plasma cells release antibodies in response to antigens. Once a B-cell becomes a mature plasma cell, it can release up to 2, 000 antibodies per second. Plasma cells are also called plasmacytes or effector cells.

Detailed explanation-2: -A lymphocyte is a type of white blood cell that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins.

Detailed explanation-3: -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.
