The correct statements about blood eosinophils are:
C. Are relatively abundant in the mucosa of the respiratory, urinary, and alimentary tracts.
D. Release cytokines.
Eosinophils are known for their role in allergic reactions and combating parasitic infections. They are typically less abundant in the blood compared to other leukocytes, and their numbers usually increase in response to parasitic infections and certain allergic conditions, not viral infections. Additionally, eosinophils have granules in their cytoplasm, not agranular.
