d5 d5 d5 d5


d. left atrium and left ventricle
d5 d5 d5 d5




ANSWER: A d5


The heart’s apex, or lower portion, is formed by the tip of the left ventricle. The apex lies
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


justabove the diaphragm, between the fifth and sixth ribs, in the midclavicular line.

ANSWER: A d5


The left atrium receives freshly oxygenated blood from the lungs via the right and

d5 d5 d5 d5 d5 d5 d5 d5 d5 .
a. left atrium d5


b. right atrium d5


c. left ventricle d5


d. right ventricle d5




ANSWER: D d5


The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


formed by portions of the right atrium and the left and right ventricles. However, because
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


the heart is tilted slightly toward the left in the chest, the right ventricle is the area of the
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


heart thatlies most directly behind the sternum.
d5 d5 5d d5 d5 d5 d5 d5




OBJ: Identify the surfaces of the heart.
d5 d5 d5 d5 d5 d5




4. Blood pressure is determined by
d5 multiplied by d5 d5 d5 d5 .
a. stroke volume; heart rate d5 d5 d5


b. heart rate; cardiac output d5 d5 d5


c. cardiac output; peripheral vascular resistance
d5 d5 d5 d5


d. stroke volume; peripheral vascular resistance
d5 d5 d5 d5




ANSWER: C d5


Blood pressure is equal to cardiac output multiplied by peripheral vascular resistance.
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5

, OBJ: Identify and explain the components of blood pressure and cardiac output.
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5




5. The right atrium receives venous blood from the head, neck, and thorax via the
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 ,
fromthe remainder of the body via the , and from the heart via the
d5 5d d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 .
a. coronary sinus; superior vena cava; inferior vena cava d5 d5 d5 d5 d5 d5 d5


b. superior vena cava; coronary sinus; inferior vena cava d5 d5 d5 d5 d5 d5 d5


c. inferior vena cava; superior vena cava; coronary sinus
d5 d5 d5 d5 d5 d5 d5


d. superior vena cava; inferior vena cava; coronary sinus d5 d5 d5 d5 d5 d5 d5




ANSWER: D d5


The right atrium receives blood low in oxygen from the superior vena cava, which
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


carries blood from the head and upper extremities; the inferior vena cava, which carries
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


blood fromthe lower body; and the coronary sinus, which is the largest vein that drains
d5 d5 5d d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


the heart.

6. The heart is divided into
d5 d5 d5 d5 chambers but functions as a d5 d5 d5 d5 -sided pump. d5


a. two; four d5


b. three; two d5


c. four; two d5


d. four; three d5




ANSWER: C d5


The heart has four chambers: two atria and two ventricles. The right and left sides of the
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


heartare separated by an internal wall of connective tissue called a septum. The interatrial
d5 5d d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


septum separates the right and left atria. The interventricular septum separates the right
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


and left ventricles. The septa separate the heart into two functional pumps. The right
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


atrium and right ventricle make up one pump. The left atrium and left ventricle make up
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


the other.

7. Stimulation of alpha1 receptors results in d5 d5 d5 d5 d5 .
a. increased heart rate d5 d5


b. peripheral vasoconstriction d5


c. constriction of bronchial smooth muscle d5 d5 d5 d5


d. increased force of myocardial contraction d5 d5 d5 d5




ANSWER: B d5


Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


organs.Stimulation of alpha1 receptor sites results in constriction.
d5 5d d5 d5 d5 d5 d5 d5 d5




OBJ: Compare and contrast the effects of sympathetic and parasympathetic stimulation of the heart.
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5




8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


a. Left
b. Right
ANSWER: B d5


The job of the right side of the heart is to pump unoxygenated blood to and through the
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


lungs to the left side of the heart. This is called the pulmonary circulation. The right side of
d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5 d5


the heartis a low-pressure system.
