Lab Blood Flashcards
what is the blood volume of an average size male
5-6L
what is the blood volume of an average size female
4-5L
what determines whether blood is bright red or a dull red
the amount of oxygen in the blood
the most numerous leukocyte
neutrophil
what are the three granulocytes
neutrophil, eosinophil, basophil
also called erythrocyte(anucleate formed element)
red blood cell
actively phagocytic leukocytes
neutrophil, monocyte
agranulocytes
lymphocyte, monocyte
precursor cell of platelets
megacaryocyte
number of these rises during parasite infection
eosinophil
releases histamine;promotes inflammation
basophil
many formed in lymphoid tissue
monocyte
transports oxygen
red blood cell
primarily water, noncellular, fluid matrix of blood
plasma
this increases in number during prolonged infections
lymphocytes
what are the five types of white blood cells
eosinophil, basophil, neutrophil, monocyte, lymphocyte
four classes of nutrients normally found in plasma
amino acids, glucose, fatty acids, vitamins
what are two gases found in plasma
carbon dioxide and oxygen
what are three ions found in plasma
sodium, potassium, and calcium
what is the average life span of a red blood cell
about 100-120 days
how does the anucleate condition of RBC affect their lifespan
it makes it unable to repair damage or reproduce thus shortening its lifespan
what are the structural characteristics of eosinophils
bilobed nucleus and cytoplasmic granules
what are the structural characteristics of neutrophils
multilobed nucleus and cytoplasmic granules
what are the structural characteristics of lymphocytes
large nucleus that takes up most of the cell
what are the structural characteristics of basophils
bilobed nucleus that is very dark and filled with cytoplasmic granules
what are the structural characteristics of monocytes
very large with U shaped nucleus
abnormal increase in the number of WBC
leukocytosis
abnormal increase in the number of RBC
polycythemia
condition of too few RBCs or with hemoglobin deficiencies
anemia
abnormal decrease in the number of WBC
leukopenia
why are hematologic studies of blood so important
blood composition can indicate the health of individuals
why are differential WBC counts so important
they indicate whether there is an increase or decrease in WBC types which indicates if there is a health problem
what is the production of RBC called
erythropoiesis
why might patients with kidney disease suffer from anemia
healthy kidneys produce erythropoietin, if they are not working correctly then RBC production will decrease
what are patients with low RBC treated with
iron supplements
the percent of RBC count in blood volume
hematocrit
if there is a high hematocrit will hemoglobin be high or low
high
what is anticoagulation
an agent that prevents coagulation
what two anticoagulants are used in conducting the hematologic tests
heparin and EDTA
what is the body’s natural aticoagulation
heparin
what condition is iron-deficient diet
microcytic hypochromic anemia
what condition is a type of bone marrow cancer
lymphocytic leukemia
what condition is a genetic defect that causes hemoglobin to become sharp/spiky
sickle cell anemia
what condition is a lack of vitamin B12
macrocytic hypochromic anemia
what condition is a tapeworm infestation in the body
eosinophilia
what condition is a bleeding ulcer
sickle cell anemia
what is the desirable range for plasma cholesterol concentration
130-200 mg
