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