White Blood Cell (WBC) Differential White blood cells (WBCs), also called leukocytes, are cells that circulate in the blood and the lymphatic system that help protect the body against infections. They are an important part of the body's immune system and also have a role in inflammation, allergic responses, and protection against cancer.

Medical Definition of White blood cell White blood cell: One of the cells the body makes to help fight infections. There are several types of white blood cells (leukocytes). The two most common types are the lymphocytes and neutrophils (also called polymorphonuclear leukocytes, PMNs, or polys).he white blood cell count is done by counting the number of white blood cells in a sample of blood. A normal WBC is in the range of 4,000 to 11,000 cells per microliter. A low WBC is called leukopenia. A high WBC is termed leukocytosis.

High white blood cell count Definition. High white blood cell count is an increase in disease-fighting cells (leukocytes) circulating in your blood. High white blood cell count is also called leukocytosis.

Medical Definition of Granular leukocyte home / medterms medical dictionary a-z list / granular leukocyte definition Medical Definition of Granular leukocyte Granular leukocyte: A type of white blood cell filled with microscopic granules (tiny sacs) containing enzymes that digest microorganisms. Granular leukocytes-- they are better known as granulocytes -- are part of the innate immune system and have somewhat non specific, broad-based activity. They do not respond exclusively to specific antigens, as do B-cells and T-cells.

Leukocytosis Leukocytosis is white cells (the leukocyte count) above the normal range in the blood.[1][2] It is frequently a sign of an inflammatory response,[3] most commonly the result of infection, but may also occur following certain parasitic infections or bone tumors as well as leukemia.

White Blood Cells White blood cells, or leukocytes, are cells of the immune system involved in defending the body against both infectious disease and foreign materials. There are several different types of white blood cells. They all have many things in common but are all distinct in form and function. They are produced in the bone marrow by hemopoeitic stem cells, which differentiate into either lymphoid or myeloid progenitor cells.

- Leukocytes The main cells of the immune system are white blood cells collectively referred to as leukocytes. Like all blood cells, leukocytes originate from the bone marrow. Stem cells (undifferentiated cells) in the marrow develop into the various white blood cells.

leukocyte a type of blood cell that lacks hemoglobin and is therefore colorless. Leukocytes are larger in size and fewer in number than erythrocytes; normally the blood has about 8000 of them per mm 3. In contrast to erythrocytes, leukocytes can move about under their own power with ameboid movement.

Leukocytes in Urine: Symptoms, Causes & Treatments Leukocytes in urine are not a dangerous condition, but they are a sign that you are suffering from an infection or damage. Leukocytes are white blood cells (WBC) that work with the immune system to defend against infectious disease. Damage to the kidneys, ureters, urethra or bladder can cause leukocytes to appear. They can also be triggered when foreign materials are found in the body.

NCI Dictionary of Cancer Terms A type of blood cell that is made in the bone marrow and found in the blood and lymph tissue. Leukocytes are part of the body’s immune system. They help the body fight infection and other diseases. Types of leukocytes are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells). Checking the number of leukocytes in the blood is usually part of a complete blood cell (CBC) test. It may be used to look for conditions such as infection, inflammation, allergies, and leukemia. Also called WBC and white blood cell.

White blood cell White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells. Leukocytes are found throughout the body, including the blood and lymphatic system. All white blood cells have nuclei, which distinguishes them from the other blood cells, the anucleated red blood cells (RBCs) and platelets. Types of white blood cells can be classified in standard ways.

What Are Leukocytes? - Definition, Types & Function Leukocytes -- a body's army of soldiers -- are a part of our immune system. They not only fight the germs that cause disease and infections, they strive to protect us against any foreign agent that appears to be a threat. Some produce weapons in the form of antibodies while others make direct attacks.
