Lymphocytes & Monocytes


Lymphocytes

    They have an important role in immune phenomena.

    These lymphocytes recognize foreign elements will lead to a reaction in order to eliminate them.

    T-cells in response to immune stimulation leading to cell proliferation (cellular immunity). They have the ability to recognize foreign objects.
    B-cells, and the production of antibodies (humoral immunity).

Monocytes

    Monocytes play a role in immune phenomena.

    Born and monocytes in the bone marrow and then transported through the blood to the tissues where it is fixed: it is a macrophage.


Blood and Refresher training


Blood and refresher training

    Hematopoiesis is the process that constitute elements of blood.

    The formation of blood cells instead of bone marrow.

    Pluripotent stem cells in the bone marrow (multiple potential). These stem cells are, after partition, which enter the cell and differentiate under the influence of different stimuli lines:

    Red blood cells: red blood cells, which leads to the formation of red blood cells is. This is the hormone erythropoietin, which regulates the proliferation and maturation of red blood cells and stimulates.

    Granulocyte colony: neutrophils reasons.

    Platelets line: Causes of platelets. Differentiation of stem cells is a function of hormone,
thrombopoietin.


    Lymphocyte line: lymphocytes reasons. This is transformed in different subpopulations: T cells and B-cells
    Monocytes leads to monocytes.
