White cells are blood cells, components of the blood that protect the body from infectious agents, also known as bacocentesis. White blood cells play an important role in the body’s immune system. They play an important role in the immune system by identifying damaged cells, removing cancer cells and foreign substances from the body. Leukocytes originate from bone marrow stem cells and circulate in the blood and lymph fluid.
White Cells Blood cells are classified based on the presence or absence of granules in their ‘cytoplasm’. A white blood cell is considered a granulocyte or agranulocyte. There are three types of granulocytes: neutrophils, eosinophils, and basophils. When viewed through a microscope, these show the granules in the white blood cells.
Neutrophils: Neutrophils play the most important role in blood circulation. They are chemically prepared for the bacteria and are transported through the tissue at the site of infection. These bacteria enter the body and spread in the disease or dead cells and destroy them. Eosinophils are phagocytic and primarily target antigen and antibody. Eosinophils are rapidly activated during prespecific infections and allergic reactions. After neutrophils, lymphocytes are the most common type of white blood cell. These cells are spherical in shape with large nuclei and very little cytoplasm. There are three types of lymphocytes, B cells and innate cells, T and B cells important for specific immune responses.
Monocytes: These cells are the largest type of white blood cells. They can have different sizes. Monocytes migrate from the blood into the tissues.
White Blood Cell Production: White blood cells are produced within the bone marrow. Some white blood cells are concentrated in the lymph nodes, spleen, or thymus gland. Blood cell production is often regulated by body structures such as lymph nodes, spleen, liver, and kidneys. During an infection or injury, more blood cells are produced than are present in the blood. To measure the number of white blood cells in the blood is known as WBB or white blood cell count. A blood test usually has a white blood cell count of 10,800-4,300. This reduction can be due to disease, radiation or bone marrow deficiency.
Types of White Blood Cells: White blood cells (WBCS) are part of the immune system that help protect the body against infection and other foreign substances. Different types of white blood cells protect the body and protect it from disease by repairing internal defects, killing harmful bacteria and making antibodies. There are several types of white blood cells:
Neutrophils: These make up about half of all white blood cells. These are usually the first cells of the immune system to respond to an invading bacteria or virus. They also work to send signals to warn other cells in the immune system.
Eosinophils: These also play an important role in fighting bacteria. They play an effective role in dealing with various diseases. Basophiles make up one percent of white blood cells. They play an important role in increasing the immune response. These cells are known to potentially cause asthma.
Lymphocytes (B and T): Play a very important role in the immune system. These cells are responsible for eliminating many foreign cells. Monocytes make up about five percent of the body. Their job is to clear dead cells from the body.
