True/False Questions

1) The myocardium receives its blood supply from the coronary arteries.

Answer: TRUE
Page Ref: 670


2) Cardiac muscle has more mitochondria and depends less on a continual supply of oxygen than
does skeletal muscle.

Answer: FALSE
Page Ref: 673


3) Anastomoses among coronary arterial branches provide collateral routes for blood delivery to
the heart muscle.

Answer: TRUE
Page Ref: 669


4) Congestive heart failure means that the pumping efficiency of the heart is depressed so that
there is inadequate delivery of blood to body tissues.

Answer: TRUE
Page Ref: 687


5) Tissues damaged by myocardial infarction are replaced by connective tissue.

Answer: TRUE
Page Ref: 670, 687


6) The left side of the heart pumps the same volume of blood as the right.

Answer: TRUE
Page Ref: 668


7) Chronic release of excess thyroxine can cause a sustained increase in heart rate and a
weakened heart.

Answer: TRUE
Page Ref: 686


8) Arterial blood supply to heart muscle is continuous whether the heart is in systole or diastole.

Answer: FALSE
Page Ref: 669-670


9) Trabeculae carneae are found in the ventricles and never the atria.

Answer: TRUE
Page Ref: 668


10) The "lub" sounds of the heart are valuable in diagnosis because they provide information
about the function of the heart's pulmonary and aortic valves.

Answer: FALSE
Page Ref: 681


11) Autonomic regulation of heart rate is via two reflex centers found in the pons.

Answer: FALSE
Page Ref: 685


12) The papillary muscles contract after the other ventricular muscles so that they can take up the
slack on the chordae tendineae before the full force of ventricular contractions sends blood
against the AV valve flaps.

Answer: FALSE
Page Ref: 670


13) An ECG provides direct information about valve function.

Answer: FALSE
Page Ref: 679


14) As pressure in the aorta rises due to atherosclerosis, more ventricular pressure is required to
open the aortic valve.

Answer: TRUE
Page Ref: 687


15) Proxysmal atrial tachycardia is characterized by bursts of atrial contractions with little pause
between them.

Answer: TRUE
Page Ref: 690
