BIOL 2404 Chapter 18 -- Cardiovascular System - Blood (TEST)
Which is going to result in significant agglutination?
Donor is type AB, recipient is type B
Which leukocytes are derived from the myeloid line?
Neutrophils, basophils, eosinophils, and monocytes
Blood plasma is slightly _________blank; if pH drifts out of the normal range, dire consequences can result from alterations in the structure of _________blank .
basic; proteins
During platelet plug formation, platelets begin to stick to
collagen with the assistance of von Willebrand factor.
If a patient becomes dehydrated, the percentage of plasma in a centrifuged sample of his or her blood would likely
decrease
One of the functions of blood is to regulate fluid levels in the body. If too much fluid escapes from the bloodstream and enters the tissues, blood pressure will
decrease
A malnourished person might have abnormally low levels of plasma proteins. As a result, colloid osmotic pressure
decreases, and there is fluid retention in the interstitial space.
The main function of leukocytes is to
defend against pathogens
Fibrinolysis involves _________blank of the fibrin framework, and it involves the protein _________blank.
destruction, plasmin
The viscosity of blood is _________blank proportional to the number of erythrocytes and _________blank proportional to the amount of fluid.
directly; indirectly
Sodium, calcium, and bicarbonate are all described as plasma
electrolytes
When blood is centrifuged and its components separate, the bottom of the tube holds the
erythrocytes
Leukocytes are the _________blank of the formed elements, and leukocytes have _________blank.
largest; prominient nuclei
When blood oxygen is _________blank, erythropoietin is released, which _________blank production of erythrocytes.
low; stimulates
Glucose is a
polar molecule, and therefore it dissolves readily in plasma.
Extensions from megakaryocytes that extend through blood vessel walls in red marrow are sliced off from the cells by the force of blood flow. These extensions are
proplatelets
Which term best describes the function of blood when considering the presence of leukocytes and antibodies?
protection
The first phase of hemostasis involves
blood vessel constriction.
To compensate for significant blood loss, the autonomic nervous system triggers
vasoconstriction and an increase in heart rate.
Which are characteristic of leukocytes? a: Smaller than erythrocytes b: Have a nucleus c: Have no hemoglobind: More numerous than erythrocytes e: Depending on type, may or may not contain granules
B,C,E
When trying to diagnose an infection that alters the percentages of leukocyte types found in the blood, it is useful for clinicians to perform
a white blood cell diffrential count
In young children, hematopoiesis occurs in most of their bones, but in adulthood it primarily occurs in
flat bone of the axial skeleton
If agglutination occurs after a blood transfusion, it may indicate
the wrong blood type was used.
A comparison of the clinical hematocrit and true hematocrit would indicate that
their values are very similar
Which term best describes the function of blood when considering the presence of carbon dioxide and endocrine hormones?
transportation
Which events occur during the recycling of aged or damaged erythrocytes? (Order is not important.) a: The heme group is converted into biliverdin. b: Bilirubin is placed in long-term storage in the liver. c: The iron ions in hemoglobin are removed. d: The iron ions are stored in the liver. e: The iron ions are stored in the red bone marrow. f: Membrane proteins and globin proteins are broken down and reused .g: The erythrocyte contents, excluding the globins, are excreted unchanged via the digestive tract.
A,C,D,F
One of the unhealthy effects of blood doping is to
increase the viscosity of the blood.
