Question

Choose the correct sequence in which fever functions as a defence mechanism.

(A) WBCs produce chemicals that raise body temperature.
(B) Pathogen reproduction rate declines.
(C) Pathogens produce toxins.
(D) Toxins trigger WBCs.

• A. B-D-C-A
• B. D-A-C-B
• C. C-D-A-B
• D. A-C-D-B

Answer 1

The correct option is C C-D-A-B

• Fever is not a disease it is a defence mechanism of the body.
• When pathogens enter the body they will release toxins into the body.
• These toxins stimulate the white blood cells and hence the white blood cells produce a chemical substance that raises the body temperature.
• The rise in body temperature reduces the rate of multiplication of pathogens and increases the rate of phagocytosis.
