MULTIPLE CHOICE zx
1. The apex of the heart is formed by the
zx zx zx zx zx zx zx zx .
a. tip of the left ventricle
zx zx zx zx
b. tip of the right atrium
zx zx zx zx
c. right atrium and right ventricle
zx zx zx zx
d. left atrium and left ventricle
zx zx zx zx
ANSWER: A zx
The heart’s apex, or lower portion, is formed by the tip of the left ventricle. The apex lies j
zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx
ustabove the diaphragm, between the fifth and sixth ribs, in the midclavicular line.

zx zx zx zx zx zx
2. The left atrium receives blood from the
zx zx zx zx zx zx .
a. pulmonary veins zx
b. aorta
c. pulmonary arteries zx
d. inferior vena cava zx zx
ANSWER: A zx
The left atrium receives freshly oxygenated blood from the lungs via the right and l
zx zx zx zx zx zx zx zx zx zx zx zx zx zx

3. The anterior surface of the heart consists primarily of the
zx zx zx zx zx zx zx zx zx .
a. left atrium zx
b. right atrium zx
c. left ventricle zx
d. right ventricle zx
ANSWER: D zx
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is fo
zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx
rmed by portions of the right atrium and the left and right ventricles. However, because the
zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx
heart is tilted slightly toward the left in the chest, the right ventricle is the area of the heart t
zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx
hatlies most directly behind the sternum.
xz zx zx zx zx zx
OBJ: Identify the surfaces of the heart.
zx zx zx zx zx zx
4. Blood pressure is determined by
zx multiplied by zx zx zx zx .
a. stroke volume; heart rate zx zx zx
b. heart rate; cardiac output zx zx zx
c. cardiac output; peripheral vascular resistance
zx zx zx zx
d. stroke volume; peripheral vascular resistance
zx zx zx zx
ANSWER: C zx
Blood pressure is equal to cardiac output multiplied by peripheral vascular resistance.

5. The right atrium receives venous blood from the head, neck, and thorax via the
zx zx zx zx zx zx zx zx zx zx zx zx zx
, fromthe remainder of the body via the zx xz zx zx zx zx zx zx

zx zx zx zx zx zx zx
c. inferior vena cava; superior vena cava; coronary sinus
zx zx zx zx zx zx zx
d. superior vena cava; inferior vena cava; coronary sinus
zx zx zx zx zx zx zx
ANSWER: D zx
The right atrium receives blood low in oxygen from the superior vena cava, which carries
zx zx zx zx zx zx zx zx zx zx zx zx zx zx
blood from the head and upper extremities; the inferior vena cava, which carries blood fr
zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx
omthe lower body; and the coronary sinus, which is the largest vein that drains the heart.

6. The heart is divided intozx zx zx zx chambers but functions as a zx zx zx zx -sided pump. zx
a. two; four zx
b. three; two zx
c. four; two zx
d. four; three zx
ANSWER: C zx
The heart has four chambers: two atria and two ventricles. The right and left sides of the he
zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx
artare separated by an internal wall of connective tissue called a septum. The interatrial sep
xz zx zx zx zx zx zx zx zx zx zx zx zx zx zx
tum separates the right and left atria. The interventricular septum separates the right and lef
zx zx zx zx zx zx zx zx zx zx zx zx zx zx
t ventricles. The septa separate the heart into two functional pumps. The right atrium and ri
zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx
ght ventricle make up one pump. The left atrium and left ventricle make up the other.

7. Stimulation of alpha1 receptors results in zx zx zx zx zx .
a. increased heart rate zx zx
b. peripheral vasoconstriction zx
c. constriction of bronchial smooth muscle zx zx zx zx
d. increased force of myocardial contraction zx zx zx zx
ANSWER: B zx
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organ
zx zx zx zx zx zx zx zx zx zx zx zx zx
s.Stimulation of alpha1 receptor sites results in constriction.
xz zx zx zx zx zx zx zx
OBJ: Compare and contrast the effects of sympathetic and parasympathetic stimulation of the heart.
zx zx zx zx zx zx zx zx zx zx zx zx zx
8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx
a. Left
b. Right
ANSWER: B zx
The job of the right side of the heart is to pump unoxygenated blood to and through the lun
zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx zx
gs to the left side of the heart. This is called the pulmonary circulation. The right side of the
