Chapter 13 Flashcards
Blood is composed of cells, or formed elements, suspended in a clear, straw-colored liquid called….
Plasma
Polymorphonuclear leukocytes (PMNs)
Or granulocytes.
Platelets are called….
Thrombocytes
What in the blood inhibits blood clotting, so clots do not form?
Anticoagulant Substances
Break down of red blood cells is called….
Hemolysis
Rh Factor
The term Rh positive (Rh+) refers to a person who is born with the Rh antigen on their red blood cells. An Rh negative (Rh-) person does not have the Rh antigen. (Named because it was first found in the blood of a rhesus monkey).

Any abnormal or pathological condition of the blood generally is referred to as a blood…
Dyscrasia.
Anemia
Deficiency in erythrocytes or hemoglobin.
Aplastic anemia
Failure of blood cell production in the bone marrow.
Pancytopenia
… occurs when stem cells fail to produce leukocytes, platelets and erythrocytes.
Hemolytic anemia
Reduction in red cells due to excessive destruction
Pernicious anemia
Lack of mature erythrocytes caused by inability to absorb vitamin B12 into the bloodstream.
Sickle cell anemia
Hereditary disorder of abnormal hemoglobin producing sickle-shaped erythrocytes and hemolysis.
FROM BOTH PARENTS
Sickle cell trait…
ONE PARENT
Thalassemia
Inherited disorder of abnormal hemoglobin production leading to hypochromia.
Hemochromatosis
Excess iron deposits throughout the body.
Hemophilia
Excessive bleeding caused by hereditary lack of factors VIII and IX necessary for blood clotting.
Purpura
Multiple pinpoint hemorrhage’s and accumulation of blood under the skin.
Leukemia
Increase in the cancerous white blood cells (leukocytes).
Remission
Disappearance of signs and symptoms of disease.
Relapse
When disease symptoms and signs reappear, necessitating further treatment.
Mononucleosis
Infectious disease marked by increased numbers of mononuclear leukocytes and enlarged crevice lymph nodes.
Complete blood count (CBC)
Determination of numbers of blood cells, hemoglobin concentration, hematocrit and red cell values.
Hematocrit (Hct)
Percentage of erythrocytes in a volume of blood.
Hemoglobin test (Hgb)
Total amount of hemoglobin in a sample of peripheral blood.
Prothrombin Time (PT)
Test of the ability of blood to clot.
Red blood cell count (RBC)
Number of erythrocytes per cubic millimeter or microliter of blood.
White blood cell count (WBC)
Number of leukocytes per cubic millimeter or microliter of blood.
Apheresis
Separation of blood into component parts and removal of a select portion from blood.
Blood transfusion
Whole blood and cells are taken from a donor and infused into a patient.
Autologous transfusion
The collection and later reinfusion of a patients own blood or blood components.
Bone marrow biopsy
Microscopic examination of a core of bone marrow removed with a needle.
Hematopoietic stem cell transplantation
Peripheral stem cells from a compatible donor are administered to a recipient.
