|
True or False. The average resting heart rate is typically established by the rhythmicity of the AV node. |
False |
|
|
True or False. Due to Frank Starling’s Law of the Heart, an increase in EDV will result in increased stroke volume. |
True |
|
|
True or False. A whistling sound hearty through the stethoscope after the second heart sound represents stenotic AV valve.true of |
True |
|
|
True or False. The heart undergoes tetanic contraction during sympathetic stimulation to squeeze out more blood. |
False |
|
|
True or False. The end-systolic volume is the maximum amount of blood in the ventricle after ventricular filling is complete. |
False |
|
|
True or False. Parasympathetic stimulation to the heart slows the rate of depolarization at the SA bam ode to decrease HR. |
True |
|
|
True or False. As the resistance of a blood vessel increases, blood flow increases if the pressure remains constant. |
False. |
|
|
True or False. Activation of the sympathetic nervous system is required for cardiac muscle to contract. |
False |
