Elements of Blood


Platelets

    Platelets are small slices in the blood, they have an essential role in hemostasis.

    Life of 8-10 days.
    Standard plates: 150000-450000 / MM3.


White blood cells

    Cells are white blood cells that play a role in defending the body against foreign substances, pathogens and inflammatory processes.

    Life is too short (2-3 days).

    And leukocytes can be divided into two groups:

    Neutrophils: granulocytes, which are in cerebrospinal fabric:
    Neutrophils.
    Basophil.
    Eosinophils.
    Mononuclear: agranulocytes: the nucleus is not fragmented, there are:
    Monocytes.
    Lymphocytes:
    Lymphocytes
    B-cell

    Leukocyte distribution is as follows:

   
    Lymphocytes: 25-33%.
    Monocytes 2-6%.
    Neutropenia 60% to 70%.
    Eosinophils: 1-3%.
    Basophils:: ,25-0, 5%.

Cores

    They have an important role in the fight against infection and inflammation. They also have a role of a killer microbes and face-to-face: phagocytosis.

    Neutrophils have a special role in the destruction of bacteria.

    White blood cells or leukocytes.
    Platelets.


RBC

    Red blood cells or red blood cells or erythrocytes anucleee the cell so that the flow in the capillaries and up to human tissue.

    Red blood cells whose sole function is to transfer carbon dioxide from the tissues to the lungs and transfer of oxygen from the lungs to the tissues: the exchange of gases.

    It contains hemoglobin protein facilitates the transport of oxygen and carbon dioxide on one of its components, heme.

    Red blood cells contain enzymes also whose mission is to produce energy in the demolition of glucose, and thus allows him to live.

    Life of 120 days.
    The level of red blood cells: 4-5500000 / MM3.
