APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -When microorganisms, such as bacteria or viruses, enter the body, neutrophils are one of the first immune cells to respond. They travel to the site of infection, where they destroy the microorganisms by ingesting them and releasing enzymes that kill them. Neutrophils also boost the response of other immune cells.

Detailed explanation-2: -Acute bacterial infections, such as pneumococcal, staphylococcal, or leptospiral infections, are the most frequent causes of infection-induced neutrophilia. Certain viral infections, such as herpes complex, varicella, and EBV infections, may also cause neutrophilia.

Detailed explanation-3: -The name neutrophil derives from staining characteristics on hematoxylin and eosin (H&E) histological or cytological preparations. Whereas basophilic white blood cells stain dark blue and eosinophilic white blood cells stain bright red, neutrophils stain a neutral pink.
