Verified step by step guidance

Understand the two types of adaptive immunity: cell-mediated and humoral immunity. Cell-mediated immunity primarily involves T cells, while humoral immunity involves B cells and the production of antibodies.

Identify the role of T cells in cell-mediated immunity. T cells are responsible for recognizing and responding to antigens presented by antigen-presenting cells (APCs) such as macrophages and dendritic cells.

Recognize the role of B cells in humoral immunity. B cells produce antibodies that bind to free antigens in the body fluids, neutralizing them or marking them for destruction by other immune cells.

Analyze the statement about antigens: Cell-mediated immunity involves antigens presented on APCs, whereas humoral immunity deals with free antigens. This highlights the different mechanisms of antigen recognition and response.

Evaluate the options given: Determine which statements correctly describe the differences between cell-mediated and humoral immunity. Consider whether each statement accurately reflects the roles and mechanisms of T cells and B cells in the immune response.
