What is the primary role of antibodies in the immune response?
To directly destroy pathogens and infected cells.
To attract white blood cells to the site of infection.
To produce hormones that regulate immune function.
To maintain body temperature during infections.
The Correct Answer is A
Explanation: To directly destroy pathogens and infected cells. Antibodies are Y-shaped proteins produced by B cells in response to a specific pathogen. They bind to the surface of the pathogen and mark it for destruction by other components of the immune system or directly neutralize the pathogen.
Incorrect choices:
b. While antibodies can attract white blood cells to the site of infection, their primary role is not to do so but rather to directly target and neutralize pathogens.
c. Antibodies do not produce hormones but are part of the humoral immune response, which involves the production of antibodies to fight off infections.
d. Antibodies do not play a role in maintaining body temperature during infections; instead, fever is a response triggered by the release of certain chemicals called pyrogens during infections.

Correct Answer is B
Explanation
Explanation: T cells are a type of lymphocyte that plays a crucial role in cell-mediated immunity. They are responsible for recognizing and directly attacking infected or abnormal cells in the body. There are two main types of T cells: cytotoxic T cells, which directly kill infected cells, and helper T cells, which assist in coordinating the immune response.
Incorrect choices:
a. B cells are responsible for the production of antibodies and are involved in the humoral immune response, which targets pathogens outside of cells. They do not directly recognize and destroy infected cells.
c. Macrophages are antigen-presenting cells that engulf and process pathogens to present their antigens to other immune cells. While they are involved in immune recognition, they do not primarily recognize and destroy infected cells.
d. Neutrophils are a type of white blood cell involved in the innate immune response. They primarily target and destroy bacteria and other foreign invaders in the body, but they do not have the specific recognition capabilities of T cells.
Correct Answer is B
Explanation
Explanation: Rheumatoid arthritis is an autoimmune disorder in which the immune system mistakenly attacks the synovium (lining of the membranes that surround the joints), causing inflammation, pain, and joint damage.
Incorrect choices:
a. Allergic rhinitis is an allergic response to airborne allergens, such as pollen or pet dander, not an autoimmune disorder.
c. Celiac disease is an autoimmune disorder triggered by the ingestion of gluten, a protein found in wheat, barley, and rye, and it primarily affects the small intestine.
d. Type 1 diabetes mellitus is an autoimmune disorder in which the immune system attacks and destroys insulin-producing beta cells in the pancreas.
