Version 2
5.1 Identify the components and physical characteristics of the blood.

c. leukocytes and thrombocytes
d. erythrocytes
2. Which of the following statements is not true?

d. Leukocytes would increase in number when the body is under attack from bacteria
3. A tube of blood is centrifuged, and then separates into three layers. What is the bottom layer, and why?
a. The bottom layer would be leukocytes, because these are white blood cells that fight off disease.
b. The bottom layer would be plasma, since it is straw-colored liquid that contains hormones and other
proteins.
c. The bottom layer would be red blood cells, since they are the heaviest cells and sink to the bottom
upon centrifugation.
d. The bottom layer would be red blood cells, because these cells contain hemoglobin that uses iron to
bind to oxygen molecules.

Figure x. Normal versus varicose ▓▓▓▓▓▓▓▓▓▓▓▓▓▓
As patients get older, your ▓▓▓▓▓▓▓▓▓▓▓▓▓▓ can lose elasticity causing them to stretch. The valves in your
▓▓▓▓▓▓▓▓▓▓ may become weak, allowing blood that should be moving toward your heart to flow backward.
Blood pools in ▓▓▓▓▓▓▓▓▓▓, and ▓▓▓▓▓▓▓▓▓▓▓ enlarge and become varicose. The ▓▓▓▓▓▓▓▓▓▓▓
appear blue because they usually contain oxygen-poor blood, which is in the process of being recirculated through
the lungs.
7. Based on the figure and description above, what blood vessel has been blacked out?
a. arteries
b. capillaries
c. veins
d. none of the above
8. Through video, we met Sun (shown to the right), who has a disorder
of his blood vessels. Due to pooling of blood in
a. The heart
b. Capillaries
c. Erythrocytes
d. Veins
5.3 Trace the pathway of blood flow through the heart.
9. Blood in the pulmonary capillaries (lungs) that has just “picked up” oxygen will next go to the:
a. left atrium
c. aorta
b. right atrium
d. through the tricuspid valve
10. Blood returning to the heart from the systemic circuit first enters what chamber of the heart?
a. left atrium
b. right atrium
c. right ventricle
d. left ventricle

14. Blood flowing into the heart from the superior and inferior vena cava flows next through which valve?
a. tricuspid valve
b. pulmonary valve
c. mitral valve
d. aortic valve
15. As in the heart dissection we performed, you take a pipette and put BLUE dye in the pulmonary artery of the
heart. You then put RED dye into the aorta of the heart. Based your knowledge of where these blood vessels go, what
color which would each chamber be?
a. The left chambers would be red. The right chambers would be blue.
b. The left chambers would be blue. The right chambers would be red.
c. The left chambers would be purple. The right chambers would be red.
d. The right chambers would be purple. The left chambers would not be dyed any color (none).
16. Similar to the heart dissection we performed, you take a pipette and put BLUE dye in the superior vena cava of
the heart. You then put RED dye into a pulmonary vein. Based your knowledge of where these blood vessels go,
what color which would each chamber be?
