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.
2. Blood pressure is the result of cardiac output and peripheral vascular resistance.
CORRECT ANSWER T
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
