Leukocytes Practice Problems

Statement A: Neutropenia refers to a decrease in the number of neutrophils, a type of white blood cell.
Statement B: Leukocytosis refers to a decrease in the total WBC count below the normal range.

Select the appropriate choice:

Match the physiological attributes of white blood cells with their corresponding functions:

1. Chemotaxis
2. Phagocytosis
3. Cytokine Production
4. Immunological Memory

a. Release signaling molecules for immune coordination.
b. Remember specific antigens for a faster immune response.
c. Migration toward sites of infection or inflammation.
d. Engulf and digest foreign particles and pathogens.
