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