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

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

3. The anterior surface of the heart consists primarily of the
cx cx cx cx cx cx cx cx cx .
a. left atrium cx
b. right atrium cx
c. left ventricle cx
d. right ventricle cx
ANSWER: D cx
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is fo
cx cx cx cx cx cx cx cx cx cx cx cx cx cx cx cx
rmed by portions of the right atrium and the left and right ventricles. However, because the
cx cx cx cx cx cx cx cx cx cx cx cx cx cx cx cx
heart is tilted slightly toward the left in the chest, the right ventricle is the area of the heart t

4. Blood pressure is determined by
cx multiplied by cx cx cx cx .
a. stroke volume; heart rate cx cx cx
b. heart rate; cardiac output cx cx cx
c. cardiac output; peripheral vascular resistance
cx cx cx cx
d. stroke volume; peripheral vascular resistance
cx cx cx cx
ANSWER: C cx
Blood pressure is equal to cardiac output multiplied by peripheral vascular resistance.

cx cx cx cx cx cx cx
ANSWER: D cx
The right atrium receives blood low in oxygen from the superior vena cava, which carries
cx cx cx cx cx cx cx cx cx cx cx cx cx cx
blood from the head and upper extremities; the inferior vena cava, which carries blood fr
cx cx cx cx cx cx cx cx cx cx cx cx cx cx cx

a. two; four cx
b. three; two cx
c. four; two cx
d. four; three cx
ANSWER: C cx
The heart has four chambers: two atria and two ventricles. The right and left sides of the he
