MULTIPLE CHOICE

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

OBJ: Identify the surfaces of the heart.

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

OBJ: Identify and describe the chambers of the heart and the vessels that enter or leave each.

3. The anterior surface of the heart consists primarily of the .
a. left atrium
b. right atrium
c. left ventricle
d. right ventricle

ANS: D
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is
formed by portions of the right atrium and the left and right ventricles. However, because the
heart is tilted slightly toward the left in the chest, the right ventricle is the area of the heart that
lies most directly behind the sternum.

OBJ: Identify the surfaces of the heart.

4. Blood pressure is determined by multiplied by .
a. stroke volume; heart rate
b. heart rate; cardiac output
c. cardiac output; peripheral vascular resistance
d. stroke volume; peripheral vascular resistance

ANS: C
Blood pressure is equal to cardiac output multiplied by peripheral vascular resistance.

, OBJ: $ y f Identify $yfand $yfexplain $yfthe $yfcomponents $yfof $yfblood $yfpressure $yfand $yfcardiac $yfoutput.
