MULTIPLE CHOICE WS




1. The apex of the heart is formed by the
WS WS WS WS WS WS WS WS .
a. tip of the left ventricle
WS WS WS WS




b. tip of the right atrium
WS WS WS WS




c. right atrium and right ventricle WS WS WS WS




d. left atrium and left ventricle
WS WS WS WS




ANSWER: A W S




The heart’s apex, or lower portion, is formed by the tip of the left ventricle. The apex lies just
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS S
W




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




OBJ: Identify the surfaces of the heart.
W S WS WS WS WS WS




2. The left atrium receives blood from the
WS WS WS WS WS WS .
a. pulmonary veins WS




b. aorta
c. pulmonary arteries WS




d. inferior vena cava WS WS




ANSWER: A W S




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

pulmonary veins. WS




OBJ: Identify and describe the chambers of the heart and the vessels that enter or leave each.
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




3. The anterior surface of the heart consists primarily of the
WS WS WS WS WS WS WS WS WS .
a. left atrium WS




b. right atrium WS




c. left ventricle WS




d. right ventricle WS




ANSWER: D W S




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




med by portions of the right atrium and the left and right ventricles. However, because the hea
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




rt is tilted slightly toward the left in the chest, the right ventricle is the area of the heart thatlies
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS S
W W




most directly behind the sternum.
S WS WS WS WS




OBJ: Identify the surfaces of the heart.
W S WS WS WS WS WS




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




b. heart rate; cardiac output WS WS WS




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




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




ANSWER: C W S




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

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




5. The right atrium receives venous blood from the head, neck, and thorax via the
WS WS WS WS WS WS WS WS WS WS WS WS WS




, fromthe remainder of the body via the WS S
W WS WS WS WS WS WS




, and from the heart via the . WS WS WS WS WS WS




a. coronary sinus; superior vena cava; inferior vena cava WS WS WS WS WS WS WS




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




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




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




ANSWER: D W S




The right atrium receives blood low in oxygen from the superior vena cava, which carries b
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




lood from the head and upper extremities; the inferior vena cava, which carries blood fromt
WS WS WS WS WS WS WS WS WS WS WS WS WS WS S
W




he lower body; and the coronary sinus, which is the largest vein that drains the heart.
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




OBJ: Identify and describe the chambers of the heart and the vessels that enter or leave each.
W S WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




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




a. two; four WS




b. three; two WS




c. four; two WS




d. four; three WS




ANSWER: C W S




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




are separated by an internal wall of connective tissue called a septum. The interatrial septum
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




separates the right and left atria. The interventricular septum separates the right and left ventr
WS WS WS WS WS WS WS WS WS WS WS WS WS WS




icles. The septa separate the heart into two functional pumps. The right atrium and right ventr
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




icle make up one pump. The left atrium and left ventricle make up the other.
WS WS WS WS WS WS WS WS WS WS WS WS WS WS




OBJ: Identify and describe the chambers of the heart and the vessels that enter or leave each.
WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS WS




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




b. peripheral vasoconstriction WS




c. constriction of bronchial smooth muscle WS WS WS WS




d. increased force of myocardial contraction WS WS WS WS




ANSWER: B W S




Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organs.
WS WS WS WS WS WS WS WS WS WS WS WS WS S
W




Stimulation of alpha1 receptor sites results in constriction. WS WS WS WS WS WS WS




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




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




a. Left
b. Right
ANSWER: B W S




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




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