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 plays a crucial role in the adaptive immune response by producing antibodies.

Learn about immunoglobulins: Immunoglobulins (Ig) are antibodies produced by B cells. They are classified into different classes based on their structure and function, including IgM, IgG, IgE, and IgA.

Identify the primary immunoglobulin on B cells: Among the different classes, IgM is the primary immunoglobulin found on the surface of B cells. It acts as a receptor for antigens and is crucial for the initial stages of the immune response.

Differentiate between the immunoglobulin classes: IgG is the most abundant antibody in the blood and extracellular fluid, IgE is involved in allergic reactions, and IgA is found in mucosal areas such as the gut and respiratory tract.

Conclude that IgM is the immunoglobulin class primarily found attached to the surface of B cells, serving as a receptor for antigen recognition and activation of the B cell.
