Immunity ( 54 Questions)
Which of the following components of the immune system is involved in both innate and adaptive immunity?
B cells are part of the adaptive immune response and produce antibodies against specific antigens. They are not involved in the innate immune response.
T cells are primarily involved in the adaptive immune response and directly attack infected or abnormal cells. They are not part of the innate immune response.
Macrophages play a dual role in both innate and adaptive immunity. As part of the innate immune response, macrophages act as phagocytes, engulfing and destroying pathogens and debris in the body. They are also antigen-presenting cells, presenting processed antigens to other immune cells to initiate the adaptive immune response.
Natural killer cells are part of the innate immune response and can directly kill infected or abnormal cells. They do not participate in the adaptive immune response.II. Immune Response and Antigen Recognition:
Explanation: Macrophages play a dual role in both innate and adaptive immunity. As part of the innate immune response, macrophages act as phagocytes, engulfing and destroying pathogens and debris in the body. They are also antigen-presenting cells, presenting processed antigens to other immune cells to initiate the adaptive immune response.

b. T cells are primarily involved in the adaptive immune response and directly attack infected or abnormal cells. They are not part of the innate immune response.
d. Natural killer cells are part of the innate immune response and can directly kill infected or abnormal cells. They do not participate in the adaptive immune response.
