EXSC 224L FINAL QUESTIONS + ANSWERS
If your instructor asked you to list the components of blood, from highest
percentage of blood volume to lowest, which of the following would you most
likely say?: Plasma, red blood cells, platelets, white blood cells
1. If your friend asked you to explain the composition of blood plasma, which
of the following would you most likely say?: It is composed of water, proteins, nutrients, and
hormones.
2. T/F: The hepatic portal vein collects blood from the vessels that drain the
liver: False
3. transport oxygen to body tissues, whereas defe
WBCs
4. Blood is a(n) tissue.: connective
5. Which of the following is a similarity among red blood cells, white blood cells,
and platelets?: They originate in red bone marrow inside the bones.
6. If your instructor asked you to explain the benefit of red blood cells ejecting their
nuclei, which of the following would you most likely say?: This allows the cells to carry
more oxygen to the tissues.
7. Which hormone, produced in the kidneys and liver, stimulates red blood cell
production?: erythropoietin
8. When a blood vessel tears, at the site adhere to the vessel's wall to close
the tear.: Platelets
9. The receives oxygen-depleted blood and empties it into the ,
whereas oxygenated blood from the lungs enters the and
empties into the .: Right
atrium, right ventricle, left atrium, left ventricle
10. If your friend asked you to explain an activity that increases cardiac output
,to the maximum, which of the following would you most likely say?: Cardiac output
increases with physical activity, rising to a maximum that may be four to seven times greater than the resting output.
11. Which of the following statements accurately compares systole and dias-
tole?: Ventricular contraction and constriction are known as systole, whereas ventricular relaxation and expansion
are known as diastole.
12. Which of the following accurately compares the heart of an adult male and
the heart of an adult female?: The heart of an adult male is slightly larger than that of an adult female.
, 13. If your instructor asked you to explain why the myocardium is thicker in the
left ventricle than it is in the right ventricle, which of the following would you
most likely say?: The left ventricle has to pump harder to overcome the high resistance required to pump blood
into the long systemic circuit, whereas the right ventricle does not need to generate as much pressure since the
pulmonary circuit is shorter and provides less resistance.
14. The conduction system of the heart regulates the electrical impulses that: -
make the heart beat
15. The heart is located within the thoracic cage, between the and
rib.: second, fifth
16. chordae tendineae attach to the leaflet margins and
prevent marginal prolapse of the leaflet, whereas chordae
tendineae an- chor the leaflets' ventricular surface to the papillary muscle
and relieve ten- sion.: Primary
secondary
17. Deoxygenated blood from the intestines drains into the: Superior and inferior mesen-
teric veins.
18. The is the largest artery in the body.: aorta
19. The provides blood supply to the brain and contains alternate
routes in case of blockage.: Circle of Willis
20. is caused by the blood flow generated by the heart as it
pumps and the resistance that blood encounters as it moves through the
enclosed vessel.: Blood pressure
21. circulation moves blood between the heart and lungs, and
circulation moves blood between the heart and the rest of
