Verified step by step guidance

Understand the role of antibodies in the immune system. Antibodies are proteins produced by B cells that help identify and neutralize foreign invaders like bacteria and viruses.

Recognize the process of antibody-mediated immune defense, which primarily involves B cells. The key steps include activation of B cells, antigen presentation, and production of antibodies.

Identify the role of B cells in the immune response. B cells are activated when they encounter an antigen, often presented by macrophages, leading to their differentiation into plasma cells that produce antibodies.

Understand the concept of clonal selection. Clonal selection refers to the process by which specific B cells are selected to proliferate and produce antibodies after encountering an antigen.

Differentiate between B cells and T cells. While B cells are directly involved in antibody production, T cells are primarily involved in cell-mediated immunity. Clonal selection of T cells is not a part of antibody-mediated immune defense.
