DPT 712: BLOOD EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED. LATEST UPDATE
average adult blood volume
~5 Liters
(6-8% of total body weight)
-45% formed elements and 55% fluid or plasma
cellular portion of blood
-hematocrit (Hct): ratio of volume of formed elements/total blood volume
normal hematocrit values
females: 36-46%
males: 41-53%
plasma
1.The straw-colored/pale-yellow liquid component of blood that remains after cellular
components have been removed
2.55% of blood volume
3.Contains water, electrolytes,
hormones, enzymes, antibodies,
proteins, clotting factors, etc.
serum
1.Lacks blood cells and clotting factors
2.Some blood tests must be conducted only on serum (albumin, liver panel)
, Why are clinicians interested in serum levels of molecules1
1. Water and other molecules are continuously exchanged between the three fluid
compartments of the body.
2. assessment of blood samples (plasma or serum) provides information about the
blood and, by extension, about the interstitial fluid and the intracellular fluid.
3. results from blood analysis provides a great deal of information
serum albumin
a.Most abundant blood protein; 50% of serum proteins
b.Synthesized in liver
c.Transport hormones (lipid soluble/non-polar), free fatty acids, drugs (affects half life),
bilirubin,
d.Responsible for creating colloid osmotic pressure or oncotic pressure
f. Deficiencies associated with kidney & liver disease and malnutrition
oncotic pressure/colloid osmotic pressure
1.A form of ______________- induced by the presence of proteins, notably albumin, in
plasma (blood/liquid)
2.Albumin displaces water molecules and influences fluid pressures
globulins
38% of blood proteins
-alpha, beta and gamma
alpha and beta globulins
1)Synthesized in the liver
2)Transport lipids, hormones, and fat-soluble vitamins
