Hematologic System Flashcards
Homeostasis
Is the process of maintaining stability in the internal environment of the body
Anemia
Reduction below normal in the number of red blood cells (RBC) per cu. mm, or in the quantity of hemoglobin per 100 ml, of blood or in the volume of packed RBCs
Angioma
A tumor whose cells tend to form blood vessels or lymph vessels; a tumor made up of blood or lymph vessels
Aplastic anemia
A disease characterized by the failure of bone marrow to produce all 3 cell lines but a major decrease in red.
Biopsy
The removal of tissue from the living body, performed to establish precise diagnosis, usually by microscope examination of that tissue
Blast
An immature cell
Blood
The fluid that circulates through the heart, arteries, capillaries and veins, carrying nutriment, and oxygen to the body cells. It is a connective tissues
Major Functions of Blood
- Transportation
- Temperature
- Acid base balance
- Immune protection
- Hemostasis
- Fluid balance
Bone Marrow
The soft material filling the cavities of the bones, made up of a meshwork of connective tissue, the meshes being filled with marrow cells, which consist variously of fat cells, nucleated hematopoietic cells (precursors of the mature cells of the blood), mature blood cells, and tissues cells. Yellow bone marrow is bone marrow of the kind in which the fat cells predominate. Red bone marrow is marrow which is the site production of red blood cells, white blood cells, and platelets.
Bone marrow transplantation
A procedure to replace bone marrow that has been destroyed by disease or other cause. Transplantation may be autologous (an individual’s own marrow saved before treatment), allogeneic (marrow donated by someone else, or syngeneic (donated by an identical twin)
CBC
Abbreviation for complete blood count
Coagulation (blood)
The sequential process in which the multiple coagulation factors interact ultimately resulting in the formation of an insoluble fibrin clot. Disorder of hemostasis- Any disorder of any stage of coagulation, such as a deficiency of prothrombin, of AHF, or of fibrin
Cyte, cyto
Cell
Cytology
Pertaining to the study of cells
Electrophoresis
The movement of charged particles in an applied electric field
emia
Suffix showing relationship to blood condition
Erythrocyte (red blood cell or corpuscle
One of the formed elements found in the peripheral blood. Normally the mature form is a non-nucleated, biconcave disc, able by virtue of its hemoglobin content to transport oxygen and carbon dioxide.
Erythro-
Red
Erythrocytosis
An abnormal increase in the number of red blood cells (erythrocytes)
Erythropoietin
A hormone recreated by the kidney which stimulates red blood cell production.
Globulin, Globin
Blood proteins
Graft Vs. Host disease
Spontaneous growth of lymphocytes from a bone marrow transplant
HCT
Abbreviation for hematocrit
Hemarthrosis
Bleeding into joint spaces. The blood seriously damages the joint and may eventually destroy it.
Hematocrit
The proportion of red blood cells in a volume of blood
Hemoglobin
The iron containing pigment of the red blood cells (erythrocytes) that carries oxygen to the cells and carbon dioxide from the cells to the lungs.
Hemolysis
The destruction of red blood cells
Hemolytic anemia
Anemia due to an increased destruction of red cells beyond the capacity of the bone marrow to compensate for the loss.
Hemophilia (factor deficiency)
Caused by deficiency in clotting factors, not platelets
A hereditary hemorrhagic tendency due to a deficiency of anti-hemophilic globulin and characterized by increased bleeding.
Hemorrhage
The escape of blood from the vessels; small hemorrhages are classified by size as petechiae (very small), purpura (up to 1 CM), and ecchymoses (larger). The accumulation of blood within a tissue is called a hematoma. Spontaneous h. - Hemorrhage occurring without overt provocation.
