Verified step by step guidance

Understand the components of the immune system: The immune system is divided into two main types of responses: humoral and cell-mediated. The humoral response involves B lymphocytes and antibodies, while the cell-mediated response involves T lymphocytes.

Identify the role of T lymphocytes: T lymphocytes, or T cells, are crucial for the cell-mediated immune response. They do not produce antibodies but instead directly attack infected cells or coordinate other parts of the immune system.

Differentiate between T lymphocytes and other immune cells: Macrophages are involved in phagocytosis and antigen presentation, B lymphocytes are responsible for antibody production, and antibodies are proteins that neutralize pathogens. T lymphocytes, however, are specifically involved in recognizing and destroying infected cells.

Recognize the types of T lymphocytes: There are different types of T cells, including helper T cells (which assist other immune cells), cytotoxic T cells (which kill infected cells), and regulatory T cells (which help control the immune response).

Conclude the major role in cell-mediated immunity: Based on the understanding of immune system components and their functions, T lymphocytes are the primary cells responsible for the cell-mediated immune response, as they directly interact with and destroy infected cells.
