Chapter 17 Flashcards
(44 cards)
centrifuged blood
55% plasma, 45% formed elements
hematocrit
% of erythrocytes in centrifuged whole blood, 45% is normal
erythrocytes
RBCs; anuclear when mature, basically sacs of hemoglobin
oxyhemoglobin
hemoglobin bound to oxygen
carbaminohemoglobin
hemoglobin bound to carbon dioxide
hemorrhagic
caused by blood loss; type of anemia
hemolytic
RBCs destroyed prematurely; type of anemia
aplastic
destruction or inhibition of the bone marrow; type of anemia
transferrin
protein that carries Fe from the liver to the bone marrow for erythropoiesis
pernicious
vitamin B12 deficiency (needed for hematopoiesis); type of anemia
thalassemia
genetic defect in Hg causing thin/delicate RBCs that break apart easily; type of anemia
sickle cell
genetic defect in the Hg causing a deformed RBC shape; type of anemia
Fe deficiency
insufficiency of iron in the diet or not enough iron during pregnancy, etc.
blood doping
- remove blood, separate RBCs, and reinject them few days before athletic event
- increase hematocrit and blood O2 carrying capability
leucopenia
too few WBCs
leukemia
cancer of the WBCs, arises in the bone marrow
mononucleosis
infection by the EB virus; symptoms are fatigue, aches, sore throat, fever
vitamin K
required by the liver to make clotting factors
streptokinase
bacterial product used as a medication that activates more plasmin which dissolves clots
heparin
- anticoagulant; secreted by granulocytes
- compound in blood that helps prevent clots from becoming too big or forming in the wrong place
hemophilia
genetic defect causing inadequate production of a clotting factor, often VIII or IX
packed red cells
RBCs that have been separated from whole blood
plasma expanders
- injected into CV system
- increases fluid portion of blood thereby increasing blood volume
hyperlipidemia
elevated lipid levels in the blood
