b. Label the 2 places blood leaves the heart with the specific name. Indicate whether
that blood is oxygenated or not & where it is going. (3 points)
Multiple Choice: Choose the best answer (1 point each)
1. The ventricles of the heart contract
a. In succession
b. Simultaneously
2. Blood that flows through the capillaries of the head, neck, arms, and upper body returns to
the heart by the
a. Inferior vena cava
c. pulmonary veins
b. Superior vena cava
d. aorta

3. Blood is deoxygenated as it passes through which of the following parts of the heart?
a. Aorta
c. left ventricle
b. Pulmonary vein
d. Right ventricle
Matching: Write the letter of the BEST answer on the line provided (Letters may be used MORE
than once). (1 point each)
1. _____Makes “lub” sound and prevents backflow of
blood into the atria
2. _____Events of one complete heartbeat
3. _____Makes “dup” sound and prevents backflow of
blood into the ventricles
4. _____During this stage, ventricles contract and the atria
relax
5. _____ Name for the pulmonary and aortic valves
A. Semilunar valves open
B. Atrial diastole
C. AV valves close
D. Ventricular systole
E. Cardiac cycle
F. Ventricular diastole
G. Semilunar valves close
6. _____ This is the only stage that for a moment both AV
& SV valves are closed.
H. Atrial Systole
I. AV valves open
7. _____Located at the junction between the right atria
and right ventricle, it temporarily delays the impulse that
it receives
.
8. _____During this stage, the atria fill with blood and the
ventricles relax.
True/False: Correct the false statement (1 point each)
1. ___________ The systemic system get deoxygenated blood that is filled with carbon dioxide
and returns back to the heart.
2. ___________ AV valves open during the cardiac cycle because volume decreases and
pressure decreases.
Mr. Bell
Anatomy and Physiology
3. ___________ Veins bring blood back to the heart while arteries carry blood away from the
heart.
4. ___________ The aortic valve only opens when pressure of blood gets to great.
5. ___________ The pulmonary veins take blood from the right ventricle to the lungs.
