Blood and Lymph: Symptomatic & Diagnostic Terms Flashcards
(49 cards)
the presence of small red blood cells
microcytosis
the presence of large red blood cells
macrocytosis
the presence of red blood cells of unequal size
anisocytosis
the presence of large, irregularly shaped blood cells
poikilocytosis
an increase in the number of immature erythrocytes in the blood
reticulocytosis
an abnormally reduced number of red blood cells
erythropenia
an abnormally reduced number of lymphocytes
lymphocytopenia
a decrease in the number of neutrophils
neutropenia
an abnormally reduced number of all cellular components in the blood
pancytopenia
breakdown of the red blood cell membrane
hemolysis
impaired immunological defenses caused by an immunodeficiency disorder or therapy with immunosuppressive agents
immunocompromised
impaired ability to provide an immune response
immunosuppression
the presence of enlarged (diseased) lymph nodes
lymphadenopathy
enlargement of the spleen
splenomegaly
- acquired immunodeficiency syndrome
- a syndrome caused by HIV(human immunodeficiency virus that renders immune cells ineffective permitting opportunistic infections, malignancies, and neurological diseases to develop; it is transmitted sexually or through exposure to contaminated blood
AIDS
a condition in which there is a reduction in the number of red blood cells, the amount of hemoglobin, or the volume of packed red cells in the blood, resulting in a diminished ability of the red blood cells to transport oxygen to the tissues
anemia
a normocytic normchromic type of anemia characterized by the failure of the marrow to produce red blood cells
aplastic anemia
a microcytic-hypochromic type of anemia characterized by a lack of iron affecting the production of hemoglobin and characterized by small red blood cells containing low amounts of hemoglobin
iron deficiency anemia
a macrocytic-normchromic type of anemia characterized by an inadequate supply of vitamin B12, causing red blood cells to become large, varied in shape, and reduced in number
pernicious anemia
any disorder characterized by abnormal function of the immune system that causes the body to produce antibodies against itself, resulting in tissue destruction or loss of function; rheumatoid arthritis and lupus are examples of autoimmune diseases
autoimmune disease
a disorder that results from the incompatibility of a fetus with an Rh-positive blood factor and a mother who is Rh-negative, causing red blood cell destruction in the fetus; necessitates a blood transfusion to save the fetus
erythroblastosis fetalis
the presence or lack of antigens on the surface of red blood cells that may cause a reaction between the blood of the mother and the fetus, resulting in fetal anemia
Rh factor
the presence of antigens
Rh positive
the absence of antigens
Rh negative
