of circulation?
a. Systole

7. An upper chamber of the heart is the:
a. antrum.
b. atrium.
c. septum.
d. ventricle.
ANS: B
The heart has two sets of chambers. The two upper chambers are called atria.

MSC: CAAHEP: I.C.5 | ABHES: 2.a
8. A lower chamber of the heart is the:
a. antrum.
b. atrium.
c. septum.
d. ventricle.
ANS: D
, The second set of chambers in the heart is referred to as the ventricles. These larger lower
chambers have thick muscular walls, which help as they pump blood to the body and the
lungs.

9. The heart muscle’s dedicated system of blood supply is the:
a. coronary arteries.
b. pulmonary arteries.
c. pulmonary veins.
d. circulatory system.
ANS: A
Coronary arteries are the heart’s dedicated system of blood supply. The coronary arteries
bring nutrients and oxygen to the heart tissue.

10. Deoxygenated blood travels to the lungs through the:
a. aorta.
b. venae cavae.
c. pulmonary arteries.
d. pulmonary veins.
ANS: C
Almost all arteries carry oxygenated blood. The exception is the pulmonary arteries. They
carry deoxygenated blood to the lungs.

a. aorta.
b. superior vena cava.
c. pulmonary veins.
d. inferior vena cava.
ANS: B

b. venae cavae.
c. pulmonary arteries.
d. pulmonary veins.
, ANS: D
Almost all veins carry deoxygenated blood, with the exception of the pulmonary veins.
They carry oxygenated blood to the heart.

a. pulmonic semilunar valve.
b. tricuspid valve.
c. mitral valve.
d. aortic semilunar valve.
ANS: B
The tricuspid valve is between the right atrium and right ventricle. It is made up of three
cusps or flaps.
