A white blood cell (wbc) count determines the concentration of white blood cells in the patients blood. A differential determines the percentage of each of the five types of mature white blood cells. Lymphocytes 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 main types of lymphocytes t cells, b cells, and natural killer cells. T cells and b cells are critical for specific immune responses and natural killer cells provide nonspecific immunity. Learn vocabulary, terms, and more with flashcards, games, and other study tools. A healthy bloodstream contains more red blood cells than white blood cells. In a healthy body, red blood cells typically make up between 40 and 50 percent of the overall blood volume. White blood cells generally compose about 1 percent of the blood volume. T cell, type of leukocyte (white blood cell) that is an essential part of the immune system. T cells are one of two primary types of lymphocytesb cells being the second typethat determine the specificity of immune responses to antigens (foreign substances) in the body.   t cells are produced in the bone marrow and later move to the thymus where they mature. Helper t cells are the major driving force and the main regulators of the immune defense. When they are present in the blood, they stay for several hours. There are many types of t cells that have specific functions, including helper t cells - helper t cells have proteins on their cell membranes called cd4. Helper t cells direct the rest of the immune system by releasing cytokines. Within the bone marrow, all blood cells begin from a single cell type called a stem cell. The stem cell divides to form immature forms of red blood cells, white blood cells, or a platelet-producing cell. Those immature cells then divide again, mature even more, and ultimately become red blood cells, white blood cells, or platelets.   a white blood cell, also known as a leukocyte or white corpuscle, is a cellular component of the blood that lacks hemoglobin, has a nucleus, is capable of motility, and defends the body against infection and disease. White blood cells carry out their defense activities by ingesting foreign materials and cellular debris, by destroying infectious agents and cancer cells, or by producing antibodies. Blood is a fluid tissue that flows through arteries, veins and capillaries in the human body. Components of blood include red blood cells, white blood cells, platelets and plasma. There are several differences between red blood cells and white blood cells in structure, function and appearance.
