Verified step by step guidance

Understand the role of the immune system: The immune system is responsible for defending the body against pathogens. It consists of various cells, each with specific functions.

Identify the types of lymphocytes: The two main types of lymphocytes are B lymphocytes (B cells) and T lymphocytes (T cells). Each plays a distinct role in the immune response.

Learn about B lymphocytes: B cells are a type of white blood cell that are primarily responsible for producing antibodies. Antibodies are proteins that specifically target and neutralize foreign invaders like bacteria and viruses.

Differentiate between B and T lymphocytes: While B cells produce antibodies, T cells are involved in cell-mediated immunity. They do not produce antibodies but help in the activation of other immune cells and directly kill infected host cells.

Review the roles of other immune cells: Macrophages are involved in phagocytosis, engulfing and digesting pathogens, while neutrophils are the first responders to infection, also engaging in phagocytosis. Neither of these cells produce antibodies.
