A white blood cell or leukocytes are an important part of the body’s natural defense systems. Leukocytes defend the body against infectious diseases and foreign materials. They envelope and digest bacteria and fungi removing them from the body. Leukocytes are found throughout the body and there are five distinct types. White blood cells make up approximately 1% of adult blood and are formed in the bone marrow. The ratio of white blood cells to red blood cells is about 1:700. The two main types of white blood cells are the Lymphocytes and the Neutrophilus. Lymphocytes are made in the lymphoid tissues such as the spleen, thymus gland and lymph nodes. These cells identify foreign objects in the body and produce antibodies to attack them. Neutrophilus are made in the bone marrow and circulate via the blood stream. They move out of the blood and into the infected area to attack the bacteria.
What Does a Low White Blood Cell Count Mean?
A low white blood cell count is known as leucopenia. A low white blood cell count can mean a number of different things. It could mean that person is fighting off an infectious disease. It can also indicate the presence of other serious health problems such as leukemia, aplastic anemia and hyperthyroidism. Low white blood cell count can also occur if you are taking certain medications which lower white blood cell production. It is also fairly common when receiving radiation treatments and chemotherapy. It is best to talk to a medical professional about any issues you may have with blood test results.
