What are the responses of human white blood cells to disease?

Answer 1

White blood cells will increase in number when you are sick. There are several types. Each will respond differently to the type of infection.
1. Neutrophils are very active and are generally the first to attack bacteria at the site of an injury.
2. Eosinophils main mode of attack is to excrete toxic compounds.
3. Monocytes enter peripheral tissues to become tissue macrophages which can engulf
large particles and pathogens.

4. Lymphocytes:
a. T cells (cell-mediated immunity) attack foreign cells directly
b. B cells (humoral immunity) differentiate into plasma cells which synthesize antibodies
c. Natural killer (NK) cells detect and destroy abnormal tissue cells such as cancers
