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
ANSWER: 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
ANSWER: 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
ANSWER: 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. stroḳe volume; heart rate
b. heart rate; cardiac output
c. cardiac output; peripheral vascular resistance
d. stroḳe volume; peripheral vascular resistance
ANSWER: C
, Blood pressure is equal to cardiac output multiplied by peripheral vascular
resistance.
