Any of the blood cells that are colorless, lack hemoglobin, contain a nucleus, and include the lymphocytes, monocytes, neutrophils, eosinophils, and basophils -- called also leukocyte, white blood corpuscle, white cell, white corpuscle.
Several types of blood cells that help defend the body against infections. Certain cancer treatments (particularly chemotherapy) can reduce the number of these cells and make a patient more vulnerable to infections. Some types of white blood cells may also help the body fight certain cancers.
Cells in the blood that fight infections and facilitate repairs of injury or wound. White blood cells include B-cells that make antibodies and T-cells that kill and consume invaders (bacteria, viruses, and cancer cells). T-cells also serve as situational managers to control the function of other T-cells and B-cells.
Any of various blood cells that have a nucleus and cytoplasm, separate into a thin white layer when whole blood is centrifuged, and help protect the body from infection and disease. White blood cells include neutrophils, eosinophils, basophils, lymphocytes, and monocytes.
refers to a blood cell that does not contain hemoglobin. White blood cells include lymphocytes, neutrophils, eosinophils, macrophages, and mast cells. These cells are made by bone marrow and help the body fight infection and other diseases.
A type of blood cell that is responsible for fighting germs and infections. White blood cells are composed of monocytes, lymphocytes, neutrophils, eosinophils, and basophils. The normal count is 5,000 to 10,000. It may be elevated or depressed in a wide variety of diseases. Chemotherapy and radiation therapy usually cause low white counts.
White blood cells are your body's "Critical Response Unit." When your body encounters unwanted bacteria, it sends an army of white blood cells to attack the intruders. This process is called chemotaxis or the inflammatory response. In acne, it causes pimples become red, swollen and painful.
Cells that fight infection. Leukocyte, White corpuscles in the blood. They are spherical, colorless, and nucleated masses involved with host defenses. Normal white blood cell counts are variable with age and sex. Normal adult range is 4,500 to 11,000 cells per cubic millimeter of blood. Slightly higher counts are seen in children. Elevated counts can be seen in cases of inflammation and infection
Any of a group of blood cells that have no hemoglobin and migrate into tissues to fight infection and digest cell debris. White blood cells (WBC) circulate in the blood and lymphatic system and harbor in the lymph glands and spleen. They are part of the immune system responsible for both directly (T cells and macrophages) and indirectly (B cells producing antibodies) attacking foreign invaders of the body.
(WBCs or Leukocytes) - Spherical shaped cells which contain nuclei and comprise the smaller number of cells of the formed elements of whole Blood. The major portion of the buffy coat is composed of white Blood cells. White Cells are protective cells in the Bloodstream. They attack bacteria by squeezing through capillary walls to reach the area of infection. (see Leukocytes)
