Chapter 1: Anatomy and Physiology
MULTIPLE CHOICE (27 questions)
Q9. The apex of the heart is formed by the .
A. tip of the left ventricle ✔ CORRECT
B. tip of the right atrium
D. left atrium and left ventricle
Explanation: 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.
Q10. The left atrium receives blood from the .
A. pulmonary veins ✔ CORRECT
B. aorta
D. inferior vena cava
Explanation: The left atrium receives freshly oxygenated blood from the lungs via the right and left
pulmonary veins.
Q11. The anterior surface of the heart consists primarily of the .
A. left atrium
B. right atrium
D. right ventricle ✔ CORRECT
Explanation: The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is
formed by portions of the right atrium and the left and right ventricles. However, because the heart is tilted
slightly toward the left in the chest, the right ventricle is the area of the heart that lies most directly behind
the sternum.
Q12. Blood pressure is determined by multiplied by .
A. stroke volume; heart rate
B. heart rate; cardiac output
D. stroke volume; peripheral vascular resistance
Explanation: Blood pressure is equal to cardiac output multiplied by peripheral vascular resistance.

Q13. The right atrium receives venous blood from the head, neck, and thorax via the , from
the remainder of the body via the , and from the heart via the .
A. coronary sinus; superior vena cava; inferior vena cava
B. superior vena cava; coronary sinus; inferior vena cava
D. superior vena cava; inferior vena cava; coronary sinus ✔ CORRECT
Explanation: The right atrium receives blood low in oxygen from the superior vena cava, which carries
blood from the head and upper extremities; the inferior vena cava, which carries blood from the lower
body; and the coronary sinus, which is the largest vein that drains the heart.
Q14. The heart is divided into chambers but functions as a -sided pump.
A. two; four
B. three; two
D. four; three
Explanation: The heart has four chambers: two atria and two ventricles. The right and left sides of the
heart are separated by an internal wall of connective tissue called a septum. The interatrial septum
separates the right and left atria. The interventricular septum separates the right and left ventricles. The
septa separate the heart into two functional pumps. The right atrium and right ventricle make up one
pump. The left atrium and left ventricle make up the other.
Q15. Stimulation of alpha1 receptors results in .
A. increased heart rate
B. peripheral vasoconstriction ✔ CORRECT
D. increased force of myocardial contraction
Explanation: Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive
organs. Stimulation of alpha1 receptor sites results in constriction.
Q16. Which side of the heart is a low-pressure system that pumps venous blood to the
lungs?
A. Left
B. Right ✔ CORRECT
Explanation: The job of the right side of the heart is to pump unoxygenated blood to and through the
lungs to the left side of the heart. This is called the pulmonary circulation. The right side of the heart is a
low-pressure system.
