MULTIPLE CHOICE as
1. The apex of the heart is formed by the
as as as as as as as as .
a. tip of the left ventricle
as as as as
b. tip of the right atriumas as as as
c. right atrium and right ventricle as as as as
d. left atrium and left ventricle
as as as as
ANSWER: A as
The heart’s apex, or lower portion, is formed by the tip of the left ventricle. The apex lies
as as as as as as as as as as as as as as as as as
justabove the diaphragm, between the fifth and sixth ribs, in the midclavicular line.
as as as as as as as as as as as as as as
OBJ: Identify the surfaces of the heart.
as as as as as as
2. The left atrium receives blood from the
as as as as as as .
a. pulmonary veins as
b. aorta
c. pulmonary arteries as
d. inferior vena cava as as
ANSWER: A as
The left atrium receives freshly oxygenated blood from the lungs via the right and
as as as as as as as as as as as as as
leftpulmonary veins.
as as as
OBJ: Identify and describe the chambers of the heart and the vessels that enter or leave each.
as as as as as as as as as as as as as as as as
3. The anterior surface of the heart consists primarily of the
as as as as as as as as as .
a. left atrium as
b. right atrium as
c. left ventricle as
d. right ventricle as
ANSWER: D as
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is
as as as as as as as as as as as as as as as
formed by portions of the right atrium and the left and right ventricles. However, because the
as as as as as as as as as as as as as as as as
heart is tilted slightly toward the left in the chest, the right ventricle is the area of the heart
as as as as as as as as as as as as as as as as as as as
thatlies most directly behind the sternum.
as as as as as as as
OBJ: Identify the surfaces of the heart.
as as as as as as
4. Blood pressure is determined by
as multiplied by as as as as .
a. stroke volume; heart rate as as as
b. heart rate; cardiac output as as as
c. cardiac output; peripheral vascular resistance as as as as
d. stroke volume; peripheral vascular resistance as as as as
ANSWER: C as
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
as as as as as as as as as as as as as ,
fromthe remainder of the body via the , and from the heart via the
as as as as as as as as as as as as as as .
a. coronary sinus; superior vena cava; inferior vena cava as as as as as as as
b. superior vena cava; coronary sinus; inferior vena cava as as as as as as as
c. inferior vena cava; superior vena cava; coronary sinus as as as as as as as
d. superior vena cava; inferior vena cava; coronary sinus as as as as as as as
ANSWER: D as
The right atrium receives blood low in oxygen from the superior vena cava, which carries
as as as as as as as as as as as as as as
blood from the head and upper extremities; the inferior vena cava, which carries blood
as as as as as as as as as as as as as as
fromthe lower body; and the coronary sinus, which is the largest vein that drains the heart.
as as as as as as as as as as as as as as as as as
OBJ: a s Identify and describe the chambers of the heart and the vessels that enter or leave each.
as as as as as as as as as as as as as as as
6. The heart is divided into
as as as as chambers but functions as a as as as as -sided pump. as
a. two; four as
b. three; two as
c. four; two as
d. four; three as
ANSWER: C as
The heart has four chambers: two atria and two ventricles. The right and left sides of the
as as as as as as as as as as as as as as as as
heartare separated by an internal wall of connective tissue called a septum. The interatrial
as as as as as as as as as as as as as as as
septum separates the right and left atria. The interventricular septum separates the right and
as as as as as as as as as as as as as as
left ventricles. The septa separate the heart into two functional pumps. The right atrium and
as as as as as as as as as as as as as as as
right ventricle make up one pump. The left atrium and left ventricle make up the other.
as as as as as as as as as as as as as as as as
OBJ: Identify and describe the chambers of the heart and the vessels that enter or leave each.
as as as as as as as as as as as as as as as as
7. Stimulation of alpha1 receptors results in as as as as as .
a. increased heart rate as as
b. peripheral vasoconstriction as
c. constriction of bronchial smooth muscle as as as as
d. increased force of myocardial contraction as as as as
ANSWER: B as
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive
as as as as as as as as as as as as
organs.Stimulation of alpha1 receptor sites results in constriction.
as as as as as as as as as
OBJ: Compare and contrast the effects of sympathetic and parasympathetic stimulation of the heart.
as as as as as as as as as as as as as
8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
as as as as as as as as as as as as as as as
a. Left
b. Right
ANSWER: B as
The job of the right side of the heart is to pump unoxygenated blood to and through the lungs
as as as as as as as as as as as as as as as as as as
to the left side of the heart. This is called the pulmonary circulation. The right side of the
as as as as as as as as as as as as as as as as as as
heartis a low-pressure system.
