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