|
Granulocyte |
White blood cells that contain granules, granules produce bleach, peroxide and super oxide |
|
|
Neutrophil |
-Most prevalent -5 lobed nucleus -does phagocytosis -respiratory burst: destroys parasites and allergies -granules makes bleach, peroxide and superoxide |
|
|
Eosinophil |
-2 labeled nuclei -phagocytose antigens and antibodies -respiratory burst -neurotoxin |
|
|
Basophil |
-in distinct nucleus -heavily granulated -rare, -makes histamine: causes swelling at the infection site -heparin: anti-coagulant |
|
|
A granulocyte |
White blood cell not containing granules |
|
|
Monocytes |
-they become macrophages at the site of infection -large -they are phagocytes: they clean up - APC ( antigen presenting cells) -they display pieces of the antigen, (epitope), go to lymph nodes & cause immune responses |
|
|
Lymphocyte |
-they have a clear cytoplasm -large with a dimpled nucleus -both large and small lymphocytes become natural killer cells or NKC |
|
|
T-cells |
They learn self and foreign cells in the thyroid gland |
|
|
B-cells |
They learn competency in the bone marrow and are specific antibodies |
|
|
Platelets |
Fragments of a cell and are coagulants |
|
|
RBC/Erythrocytes |
-Formed elements -Not true cells, contain no nucleus and no organelles -there are 280 million hemoglobin per red blood cell -Life expectancy of 120 days, then are destroyed by the spleen and liver |
|
|
Clotting |
Coagulation |
|
|
Clotting Process |
1. Vascular spasm, a cut blood vessel, nerve endings spasm, platelets make serotonin which causes the spasm 2. Platelet plug, platelets stick to collagen and each other, and constrict to reduce blood loss 3. Coagulation |
|
|
Extrinsic |
Damaged tissue thromboplastin leads to production of factor 10, a.k.a. "X" , which activates prothrombin produced by the liver, ect. |
|
|
Intrinsic |
Slow flow inflammation |
