75
Angina threshold is reached easily; steeper slope of MVO2 increase in UE or LE exercise?
UE
Because UE has smaller diameter blood
vessels and is much closer to the heart → received more blood easily

77
T/F: During exercise → DBP should remain constant
/ increase a very little only

78
T/F: If there is too much decrease in DBP during
exercise, it means that the heart is no longer resting (Diastole = representation of heart rest)
False. It should be: If there is too much INCREASE in DBP during exercise, it means that the heart is no longer resting (Diastole = representation of heart rest)
79
What will happen next if there is a reduction on the amount of blood that goes inside the heart (ventricle)?
