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

2. The left atrium receives blood from the
cc cc cc cc cc cc .
a. pulmonary veins cc
b. aorta

d. inferior vena cava cc cc
ANSWER: A cc
The left atrium receives freshly oxygenated blood from the lungs via the right and left

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

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

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

7. Stimulation of alpha1 receptors results in cc cc cc cc cc .
a. increased heart rate cc cc
b. peripheral vasoconstriction cc
c. constriction of bronchial smooth muscle cc cc cc cc
d. increased force of myocardial contraction cc cc cc cc
ANSWER: B cc
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organs.
cc cc cc cc cc cc cc cc cc cc cc cc cc
Stimulation of alpha1 receptor sites results in constriction.
cc cc cc cc cc cc cc cc
OBJ: Compare and contrast the effects of sympathetic and parasympathetic stimulation of the heart.
cc cc cc cc cc cc cc cc cc cc cc cc cc
8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc
a. Left
b. Right
ANSWER: B cc
The job of the right side of the heart is to pump unoxygenated blood to and through the
cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc
lungs to the left side of the heart. This is called the pulmonary circulation. The right side
cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc cc
of the heart is a low-pressure system.
