Verified step by step guidance

Understand the role of B cells in the immune system: B cells are a type of white blood cell that play a crucial role in the adaptive immune response by producing antibodies.

Recognize the process of B cell activation: When a B cell encounters its specific antigen, it becomes activated and undergoes a process called clonal expansion, where it proliferates and differentiates.

Identify the differentiation of activated B cells: Upon activation, B cells differentiate into two main types of cells: memory B cells and plasma cells.

Define plasma cells: Plasma cells are the antibody-secreting progeny of activated B cells. They are responsible for producing and releasing large quantities of antibodies into the bloodstream to help neutralize pathogens.

Distinguish plasma cells from other immune cells: Unlike sensitized T cells or activated macrophages, plasma cells are specifically derived from B cells and are specialized in antibody production.
