MULTIPLE CHOICE ne




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



b. tip of the right atrium
ne ne ne ne



c. right atrium and right ventricle
ne ne ne ne



d. left atrium and left ventricle
ne ne ne ne




ANS: A ne



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



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




OBJ: n e Identify the surfaces of the heart. ne ne ne ne ne




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



b. aorta
c. pulmonary arteries ne



d. inferior vena cava ne ne




ANS: A ne



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



pulmonary veins.
ne ne




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




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



b. right atrium ne



c. left ventricle ne



d. right ventricle ne




ANS: D ne



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



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



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



heart that lies most directly behind the sternum.
ne ne ne ne ne ne ne ne




OBJ: n e Identify the surfaces of the heart. ne ne ne ne ne




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



b. heart rate; cardiac output ne ne ne



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



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




ANS: C ne



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

, OBJ: n e Identify and explain the components of blood pressure and cardiac output.
ne ne ne ne ne ne ne ne ne ne




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



the remainder of the body via the
ne ne , and from the heart via the ne ne ne ne ne ne ne ne ne ne ne .
a. coronary sinus; superior vena cava; inferior vena cava
ne ne ne ne ne ne ne



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



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



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




ANS: D ne



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



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



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




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




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



a. two; four ne



b. three; two ne



c. four; two ne



d. four; three ne




ANS: C ne



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



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



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



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



right ventricle make up one pump. The left atrium and left ventricle make up the other.
ne ne ne ne ne ne ne ne ne ne ne ne ne ne ne ne




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




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



b. peripheral vasoconstriction ne



c. constriction of bronchial smooth muscle ne ne ne ne



d. increased force of myocardial contraction ne ne ne ne




ANS: B ne



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



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




OBJ: n e Compare and contrast the effects of sympathetic and parasympathetic stimulation of the heart.
ne ne ne ne ne ne ne ne ne ne ne ne




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



a. Left
b. Right
ANS: B ne



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



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



the heart is a low-pressure system.
