Neutrophil
most abundant white blood cell, a type of granulocyte
Neutrophils are a type of phagocytic white blood cell and part of innate immunity. More specifically, they form the most abundant type of granulocytes and make up 40% to 70% of all white blood cells in humans. Their functions vary in different animals. In humans they participate in processes such as sterile inflammation, tissue repair, and cancer, and exhibit coordinated collective behavior. They are also known as neutrocytes, heterophils or polymorphonuclear leukocytes.
They are formed from stem cells in the bone marrow and differentiated into subpopulations of neutrophil-killers and neutrophil-cagers. They are short-lived (between 5 and 135 hours) and highly mobile, as they can enter parts of tissue where other cells/molecules cannot. Neutrophils may be subdivided into segmented neutrophils and banded neutrophils (or bands). They form part of the polymorphonuclear cells family (PMNs) together with basophils and eosinophils.
The name neutrophil derives from staining characteristics on hematoxylin and eosin (H&E) histological or cytological preparations.
“Neutrophil” enters the record as most abundant white blood cell, a type of granulocyte. Crown Archives preserves that source wording while asking what Neutrophil, most and abundant can confirm, complicate or overturn.
Why this record matters
“Neutrophil” is worth following because a concise public description often conceals a longer documentary argument. Here, Neutrophil, most and abundant provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 21, 2026. The linked authority identifier is Q188417. The Library of Congress control number is sh85091230. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
