Neutrophils
are key mediators of the inflammatory response, and program antigen presenting cells to activate T cells and release localized factors to attract monocytes and dendritic cells [7].
Which type of WBC is involved in the inflammatory response?
The main phagocytes involved in acute inflammation are
the neutrophils
, a type of white blood cell that contains granules of cell-destroying enzymes and proteins.
What do white blood cells do in the inflammatory response?
The chemicals that trigger an inflammatory response attract leukocytes to the site of injury or infection. Leukocytes are white blood cells. Their role is to
fight infections and get rid of debris
.
How does WBC respond to infection?
Primary response to infection
If a pathogen enters your body, white blood cells of your immune system
quickly recognise its foreign antigens
. This stimulates specific lymphocytes to grow, multiply and finally produce antibodies that will stick to the antigens on the invading pathogens and destroy them.
How much WBC count is normal?
The normal number of WBCs in the blood is
4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 10
9
/L)
. Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens.
What are three signs of the inflammatory response?
The four cardinal signs of inflammation are
redness (Latin rubor), heat (calor), swelling (tumor), and pain (dolor)

In what two ways can white blood cells fight infection?
White blood cells carry out their defense activities by
ingesting foreign materials and cellular debris
, by destroying infectious agents and cancer cells, or by producing antibodies.

help the body fight infection and other diseases
. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).
What is an alarming WBC count?
In general, for adults a count
of more than 11,000 white blood cells
(leukocytes) in a microliter of blood is considered a high white blood cell count.
What is the lowest WBC count?
In general, for adults a count
lower than 4,000 white blood cells per microliter of blood
is considered a low white blood cell count. For children, that threshold varies with age.
Is white blood cell count of 22000 high?
A normal white blood cell count is generally about 4,500 to 11,000/μL. White blood cell counts that are too high or too low may be dangerous, depending on the cause. A high white blood cell count is called
leukocytosis
, which is generally diagnosed when white blood cell levels exceed 11,000/μL.
