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