chapter 8 blood pt.3

anemia

blood disorders involving either a reduction in the number of circulating erythrocytes or the amount of hemoglobin in red blood cells; results in decreased oxygen delivery to tissues.

hemophilia

Inherited lack of a vital clotting 

  factor; results in an almost 

     complete inability to 

             stop bleeding.

leukemia

Cancer of leukocyte-forming red bone marrow; the patient has a large number of abnormal and immature leukocytes circulating in the blood.

polycythemia 

Condition characterized by too many erythrocytes, blood becomes too thick to flow easily  through blood vessels

Sickle cell Disease

Abnormally shaped red blood cells that can block blood flow and lead to various complications. These red blood cells, instead of being flexible and disc-shaped, become rigid and crescent-shaped (sickle-shaped). This abnormal shape prevents them from moving easily through small blood vessels, causing blockages and leading to pain, organ damage, and other health problems. 

thrombocytopenia

Deficiency in thrombocytes or clotting cells. 

Bone marrow aspiration

Removal of a small sample of bone marrow by needle for examination for diseases such as leukemia. 

Blood Transfusion

Transfer of blood from one

 person to another

phlebotomy

Removal of a blood specimen from a vein for laboratory tests; also called venipuncture

hemoglobin (Hgb, hb)

hem/ = rw = blood

-globin = S - protein

Blood test that measures the amount of hemoglobin present in a given volume of blood

hematocrit (HCT, Hct,)

Blood test that measures the volume of red blood cells within the total volume of blood or percentage of RBC’s to plasma

Prothrombin time

Blood test that measures how long it takes blood to clot.  

Erythropoiesis

• erythr/o = network

• -poiesis = formation or production

So it means formation of red blood cells .
