Chapter 11 Quiz
Red Bone Marrow
In Adults, the stem cells responsible for the production of red and white blood cells originate primarily in the
hemoglobin structure
composed of two pairs of globular proteins called subunits
Erythropoietin
formed by the kidneys and live, appears in the plasma when peripheral tissues, especially kidneys, are exposed to low oxygen concentrations
anemia
is a condition in which the oxygen-carrying capacity of RBCs is reduced
fibrinogen
major class of plasma protein involved with blood clotting
extracellular fluid
plasma and interstitial fluid account for most of the volume of ___________ in the body.
eosinophil
WBC that increases in activity and abundance during allergic reactions and parasitic infections
basophil
WBC that releases heparin and histamine to promote inflammation
thrombus
a blood clot attached to the wall of a vessel is called
hypoxia
a low oxygen level in tissues
ca2+
blood clotting requires this particular ion
transport nutrients and wastes
blood functions to
low blood oxygen
erythropoietin is mainly released in response to
red blood cells and white blood cells
formed elements of blood include
sickle cell anemia
genetic disease characterized by mutant hemoglobin which causes incorrectly shaped rbcs
red bone marrow
in adults, the main site of red blood cell and white blood cell production
Whole Blood
refers to the combination of plasma and the formed elements together
120 days

which of the following begins with the activation of plasminogen
neutrophil
wbc that is the most abundant and usually first to respond to an infection
RBCs life span
120 days
Serum
plasma minus the clotting proteins like fibrinogen
water and dissolved substances
plasma of blood consists of
Albumins
plasma proteins that are necessary for blood to maintain osmotic pressure are
emboli
drifting blood clots, air bubbles, or fat globules are called

during the recycling of hemoglobin, what is the breakdown product of the globular proteins of each hemoglobin molecule?
pernicious anemia
a toxin that blocks the stomach's ability to release intrinsic factor causing decreased absorption of vitamin b12
cell membrane antigens
abo blood type is determined by
transport oxygen
the major function of hemoglobin
neutrophil
the most abundant type of WBC in a normal blood sample is the _________
hematocrit
the percentage of whole blood volume occupied by cellular elements is termed (the)
vascular, platelet, and coagulation
the phases of hemostasis
an enzyme that converts fibrinogen to fibrin
thrombin is
