Clonal Selection of B Cells

An immune system diagram illustrating clonal selection of B cells explains how specific antibodies are produced. It shows a diverse population of B cells, each with a unique receptor, and highlights how only the cell that binds a matching antigen becomes activated. That selected B cell then multiplies into identical clones, some becoming plasma cells that secrete antibodies and others forming memory cells. Arrows and labels emphasize expansion and differentiation. This visual helps explain immune specificity, memory, and why vaccines create long-lasting protection.
