Overview
White blood cells, also known as leukocytes, are responsible for protecting your body from infection. As part of your immune system, white blood cells circulate in your blood and respond to injury or illness.
Function
White blood cells protect your body against infection. As your white blood cells travel through your bloodstream and tissues, they locate the site of an infection and act as an army general to notify other white blood cells of their location to help defend your body from an attack of an unknown organism.
Anatomy
Your white blood cells are in your bloodstream and travel through blood vessel walls and tissues to locate the site of an infection.
Conditions and Disorders
If you have a low white blood cell count, you are likely to get infections ( leukopenia ). If your white blood cell count is too high ( leukocytosis ), you may have an infection or an underlying medical condition like leukemia, lymphoma or an immune disorder.
Why are white blood cells called white?
The reason for white blood cells being called white, is due to their physical appearance. After separating them from the red blood cells, the cells are indeed white in colour. The same goes for red blood cells, they are red in appearance.
Why are white blood cells important?
White blood cells are essential for helping the immune system fight off infections. They are bigger than red blood cells, are fewer in number but have an equally effective impact. Maintaining a healthy white blood cell count is essential for inhibiting infections.
What type of cells have a nucleus?
The White Blood Cells (wbcs) or Leukocytes are the type of cells that have a nucleus and float freely in your bloodstream. Bone marrow, lymph glands, and nodes are the primary sources where WBCS gets produced. They pass directly to the bloodstream and live from several days to many years.
What percentage of white blood cells are in the lymphatic system?
One of the most valuable wbcs types existing in your body. They count for almost 30% of the total white blood cell population in your bloodstream. However, they are more apparent in the lymphatic system than in your blood.
Why is my white blood count high?
This high number of leukocytes, known as Leukocytosis, could be the response to a recent illness and germ infection.
What is the only white blood cell that has two or three lobes?
Basophil. Scientists have found these white blood cells to be rare in your body, counting for less than 0.4% of the total immune system cells. They are the only ones who have two or three lobes, and their cytoplasm granules can take blue color under the microscope.
How big is a white blood cell?
This type of white blood cell has the same size as the neutrophils ( 10-12μm ). Their name comes from the pink color they take under the microscope when the doctor uses a cell pigmentation method.
What is a white blood cell?
white blood cell. A cell in the general circulation that is whitish to the naked eye when centrifuged. Types. Nonspecific immune response cells—e.g., monocytes and granulocytes (neutrophils, basophils and eosinophils)—and specific immune response cells—B and T lymphocytes.
What are leukocytes in the body?
A type of cell formed in the myelopoietic, lymphoid, and reticular portions of the reticuloendothelial system in various parts of the body, and normally present in those sites and in the circulating blood. Under various abnormal conditions, the total number of leukocytes may be increased or decreased or their relative proportions altered, and they may appear in other tissues and organs. Leukocytes represent three lines of development from primitive elements: myeloid, lymphoid, and monocytic series. On the basis of features observed with various methods of staining with polychromatic dyes, cells of the myeloid series are frequently termed granular leukocytes, or granulocytes; because the cytoplasmic granules of lymphocytes and monocytes are smaller and frequently not clearly visualized with routine methods, these cells are sometimes termed nongranular or agranular leukocytes. Granulocytes are commonly known as polymorphonuclear leukocytes (also polynuclear or multinuclear leukocytes), because in a mature cell the nucleus is divided into two to five rounded or ovoid lobes that are connected with thin strands or small bands of chromatin; they consist of three distinct types: neutrophils, eosinophils, and basophils, named on the basis of the staining reactions of the cytoplasmic granules. Cells of the lymphocytic series are smaller than other leukocytes and have relatively large, darkly staining, eccentrically placed nuclei. Cells of the monocytic series are usually larger than the other leukocytes and are characterized by a relatively abundant, slightly opaque, pale blue or blue-gray cytoplasm that contains many fine reddish-blue granules. Monocytes are usually indented, reniform, or shaped similarly to a horseshoe, but are sometimes rounded or ovoid; their nuclei are usually large and centrally placed and, even when eccentrically located, are completely surrounded by at least a small band of cytoplasm.#N#Synonym (s): white blood cell, leucocyte.
What is a myelopoietic cell?
A type of cell formed in the myelopoietic, lymphoid, and reticular portions of the reticuloendothelial system in various parts of the body, and normally present in those sites and in the circulating blood (rarely in other tissues). Under various abnormal conditions the total numbers or proportions, or both, may be characteristically increased, ...
What is a leukocyte hematocrit?
Leukocyte Hematology A cell in the general circulation which is whitish to the naked eye when centrifuged Types Nonspecific immune response cells–eg, monocytes and granulocytes–neutrophils, basophils and eosinophils and specific immune response cells, B and T lymphocytes. See Granulocyte, Lymphocyte, Monocyte.
Where are pyramidal cells located?
Pyramidal cells are flask-shaped or triangular, and, in the parts of the cortex with six layers, they occupy the fifth layer. Pyramidal cell dendrites project up into the most superficial layer of the cortex, while pyramidal cell axons run in the opposite direction, i.e., downward and out of the cortex.
Which type of cell is found in epithelial tissues and helps T cells respond to foreign antigens?
One type of antigen-presenting cell that helps T cells respond to foreign antigens. Dendritic cells are found in epithelial tissues and include the Langerhans' cells of the skin and the interdigitating cells in lymph nodes; they also circulate in the blood.
Where is plasmacyte found?
It may be found in the blood or in tissue fluid. Synonym: plasmacyte
Why do we need white blood cells?
White blood cells are part of the immune system. They help your body fight off infections and other diseases. When you get sick, your body makes more white blood cells to fight the bacteria, viruses, or other foreign substances causing your illness. This increases your white blood count.

If you are already being treated for a white blood cell disorder, your results may show if your treatment is working or whether your condition has improved. If you have questions about your results, talk to your health care provider.
What is a blood test for neutrophils?
A blood differential test shows the amount of each type of white blood cell, such as neutrophils or lymphocytes. Neutrophils mostly target bacterial infections. Lymphocytes mostly target viral infections. A higher than normal amount of neutrophils is known as neutrophilia.
What is the name of the test that measures the amount of white blood cells in your blood?
