name two specific types of leukocytes or derivatives of leukocytes that are phagocytotic?

Question

from microbiology

Answer 1

Leukocytes and Derivatives are as follows ==

1)granulocyte - Any of a group of white blood cells having many large granules in their cytoplasm and distinctive lobular (polymorphic) nuclei; three subgroups are recognized based on the staining properties of the granules: neutrophils, eosinophils, and basophils.

A) Neutrophil = polymorphonuclear leukocyte - The most abundant type of granulocytic white blood cell (60-70% of total WBCs) which is the rapid responder to sites of injury and inflammation and is highly destructive of microorganisms, especially bacteria; its granules stain poorly and appear pale gray to lavender in typical blood stains.

It is capable of phagocytosis and will participate in the removal of damaged tissues even in the absence of infection.

B)Eosinophil - The type of granulocytic white blood cell (2-4% of total WBCs), containing large cytoplasmic granules which are stained red by eosin or other acid dyes.

It is capable of phagocytosis and participates primarily in immune responses against multicellular parasites (worms) and is also involved in certain hypersensitivities (allergies).

3 ) Basophil - The least abundant type of white blood cell (0.5-1.0% of total WBCs).

A Non Phagocytic granulocyte containing large cytoplasmic granules which are stained blue with basic dyes; the granules contain immune regulatory substances including heparin, histamine and serotonin; these cells resemble and may be developmentally related to tissue mast cells (tissue basophils).

SO OUT OF THE THREE ABOVE ONLY TWO ARE PHAGOCYTIC .




Monocyte - The largest type of white blood cell (3-8% of total WBCs).

a phagocytic agranulocyte, having a single well-defined, often kidney-bean shaped, nucleus and very fine granulation in the cytoplasm; they have long lifespans and when they emigrate into tissues they differentiate into various types of macrophages; they are slow responders to sites of injury and inflammation and are highly destructive of microorganisms.

Macrophage - Any of the large long-lived phagocytic cells derived from monocytes comprising a major component of the diffuse immune system (sometimes called the reticuloendothelial system or, more recently, the mononuclear phagocytic system).

Macrophages from different sites have somewhat different properties; in addition to contributing to the killing of microorganisms and tumor cells; the release immune regulatory substances and play a vital role in antigen-presentation leading to the production of antibodies by B lymphocytes and the activation of T lymphocytes.

Answer 2

Two Types Of Leukocytes

Answer 3

Leukocytes include: Neutrophils, Lymphocytes, Monocytes, Eosinophils, and Basophils ("Neutrophils Like Making Everything Better" is a way to remember that). Monocytes differentiates into macrophages in tissues (macrophages phagocytose bacteria, cell debris, etc). I believe the other one is either the eosinophil or neutrophil.

Answer 4

neutrophil and moncyte
