TRUE/FALSE
1. Stimulation of beta-adrenergic receptor sites will result in peripheral vasoconstriction.
CORRECT ANSWER: F
Beta receptor sites are divided into beta1 and beta2. Beta1 receptors are found in the heart and kidneys.
Stimulation of beta1 receptor sites in the heart results in increased heart rate, contractility, and ultimately
irritability of cardiac cells. Stimulation of beta1 receptor sites in the kidneys results in the release of renin into
the blood. Renin promotes the production of angiotensin, a powerful vasoconstrictor. Beta2 receptor sites are
found in the arterioles of the heart, lungs, and skeletal muscle. Stimulation results in dilation.
Stimulation of beta2 receptor sites in the smooth muscle of the bronchi results in dilation.
OBJ: Compare and contrast the effects of sympathetic and parasympathetic stimulation of the heart.

, Blood pressure is equal to cardiac output multiplied by peripheral vascular resistance. Blood pressure is the
force exerted by the circulating blood volume on the walls of the arteries.
Peripheral vascular resistance is the resistance to the flow of blood determined by blood vessel diameter and
the tone of the vascular musculature.
OBJ: Identify and explain the components of blood pressure and cardiac output.
MULTIPLE CHOICE
1. The apex of the heart is formed by the .
a. tip of the left ventricle
b. tip of the right atrium
c. right atrium and right ventricle
d. left atrium and left ventricle CORRECT ANSWER: A
The heart’s apex, or lower portion, is formed by the tip of the left ventricle. The apex lies just above the
diaphragm, between the fifth and sixth ribs, in the midclavicular line.
OBJ: Identify the surfaces of the heart.
2. The left atrium receives blood from the .
a. pulmonary veins
b. aorta
c. pulmonary arteries
d. inferior vena cava CORRECT ANSWER: A
The left atrium receives freshly oxygenated blood from the lungs via the right and left pulmonary veins. 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 .

, d. right ventricle CORRECT ANSWER: D
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is formed by portions
of the right atrium and the left and right ventricles. However, because the heart is tilted slightly toward the left
in the chest, the right ventricle is the area of the heart that lies most directly behind the sternum.
OBJ: Identify the surfaces of the heart.
4. Blood pressure is determined by multiplied by .
a. stroke volume; heart rate
b. heart rate; cardiac output
c. cardiac output; peripheral vascular resistance
d. stroke volume; peripheral vascular resistance CORRECT ANSWER: C
Blood pressure is equal to cardiac output multiplied by peripheral vascular resistance. 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 , from the remainder of the
body via the , and from the heart via the .
a. coronary sinus; superior vena cava; inferior vena cava
b. superior vena cava; coronary sinus; inferior vena cava
c. inferior vena cava; superior vena cava; coronary sinus
d. superior vena cava; inferior vena cava; coronary sinus CORRECT ANSWER: D
The right atrium receives blood low in oxygen from the superior vena cava, which carries blood from the head
and upper extremities; the inferior vena cava, which carries blood from the lower body; and the coronary sinus,
which is the largest vein that drains the heart.
OBJ: Identify and describe the chambers of the heart and the vessels that enter or leave each.
6. The heart is divided into chambers but functions as a -sided pump.
