Refer to Figure 1 for questions 1-4.
Figure 1: Cross Section of a Blood Vessel
1. The inner most layer of the blood vessel (label 1
on the figure to the right) is called the
A. intima.
B. media.
C. tunica adventitia.
2. The endothelial cells that make up the inner most
layer (label 1) act like a “gate” because they can

A. stretch to reshape the vessel lining and
stick to surrounding muscle.
B. open spaces to allow things in or touch
closely together creating a tight seal.
C. swing in and out to the center of the vessel
to push the blood through.

3. The tunica adventitia (label 3 on Figure 1) is a strong blood vessel layer that helps
A. connect the blood vessel to surrounding tissue.
B. stretch and contract as blood flows through the vessel.
C. carry oxygen-poor blood away from the lungs.
4. The flexible and “elastic” blood vessel parts labeled 4, 5, and 6 combine to make the media which
A. anchors the blood vessel to surrounding body tissues and helps it maintain its shape.
B. controls the substances that are allowed to move into or out of the blood vessel.
C. allows the blood vessel to maintain its normal size or stretch as blood moves through it.
5. Arteries are blood vessels that typically carry blood away from the
A. heart to the body and lungs.
B. body and lungs to the heart.
C. right lung to the left lung and heart.

6. Pulmonary arteries carry
A. oxygen-poor blood.
B. oxygen-rich blood.
C. oxygen-neutral blood.
Refer to Figure 2 for question 7.
Figure 2: Cross Section of Arteries and Veins
7. In the cross-section to the right, why is there a
difference in the size of the media of the artery
and the media of the vein?
A. The media of the artery must pull the
adventitia away from surrounding tissue.
B. The media of the vein must be thinner to
allow blood to move to the surrounding
tissue.
C. The media of the artery must be thicker to
withstand higher blood pressure forcing
through it.
Refer to Figure 3 to “fill in the blanks” for items 8-11.
Figure 3: Blood Vessels
8-11. From the lungs, oxygen-rich blood moves through
tiny capillaries, arterioles, and arteries leading to the
__8__ where it is pumped to the rest of the body
through large elastic arteries that branch into smaller
arteries, arterioles, and finally into __9__ surrounding
the body cells. Here, oxygen and nutrients are
diffused out into the body cells, while carbon dioxide
and other byproducts are diffused into the blood and
carried back to the heart, then the lungs through large
__10__ which divide into smaller and smaller vessels
until the vessel is thin enough to allow carbon dioxide
to diffuse out into the __11__.

B. veins carry blood away from the heart.
C. capillaries carry blood away from the heart.

13. What structures of the capillaries make it possible for diffusion of gases between the blood and the
body cells?
A. thick tunica adventitia layers
B. thin muscle and endothelium layers
C. muscular media layers
14. What features of veins make them capable of doing the job for which they are designed?
A. Non-elastic layers, thick adventitia, and check valves
B. Small lumen, thick and muscular media, and thin adventitia
C. Internal and external elastic layers with endothelial cells
15. Inhaled oxygen molecules diffuse through the walls of the _____ in the lungs.
A. artery
B. alveoli
C. arterioles
16. Energy is released when _____ is broken down by oxygen.
A. glucose
B. energy
C. blood
17. _____ travel single file through the capillaries so that materials can be diffused into or out of the
circulatory system.
A. glucose molecules
B. white blood cells
C. red blood cells
