Fevers
decrease the concentration of iron in the blood.
The correct answer is Option B
Explanation of correct option:
A single event of fever and/or inflammation in a person appears to inhibit the reticuloendothelial system's release of iron from red blood cells, resulting in a drop in serum iron content and long-term stimulation of ferritin formation.
Explanation of incorrect option:
Option A:
Interferons are a family of signaling proteins that are produced and released by host cells in response to the presence of a variety of viruses. Fever does not reduce interferon production.
Option C:
Phagocyte is a kind of cell capable of ingesting and digesting foreign particles such as bacteria, carbon, dust, or dye. Fever does not decrease the activity of phagocytes.
Option D:
Fever increases the body temperature and increased body temperature does not allow the growth of bacteria.
Final answer: Fevers decrease the concentration of iron in the blood.
