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 justabove 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 leftpulmonary 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 thatlies 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: Identify and explain the components of blood pressure and cardiac output.
5. The right atrium receives venous blood from the head, neck, and thorax via
the , fromthe remainder of the body via the ,
and from the heart via the .
a. coronary sinus; superior vena cava; inferior vena cava
b. superior vena cava; coronary sinus; inferior vena cava
c. inferior vena cava; superior vena cava; coronary sinus
d. superior vena cava; inferior vena cava; coronary sinus
ANS >> D
The right atrium receives blood low in oxygen from the superior vena cava,
which carries blood from the head and upper extremities; the inferior vena
cava, which carries blood fromthe lower body; and the coronary sinus, which
is the largest vein that drains the heart.
OBJ: Identify and describe the chambers of the heart and the vessels that enter
or leave each.
6. The heart is divided into chambers but functions as a -sided pump.
a. two; four
b. three; two
c. four; two
d. four; three
ANS >> C
The heart has four chambers: two atria and two ventricles. The right and left
sides of the heartare separated by an internal wall of connective tissue called a
septum. The interatrial septum separates the right and left atria. The
interventricular septum separates the right and left ventricles. The septa
separate the heart into two functional pumps. The right atrium and right
ventricle make up one pump. The left atrium and left ventricle make up the
other.
OBJ: Identify and describe the chambers of the heart and the vessels that enter
or leave each.
