most people assume that during exercise, both diastolic and systolic pressure will increase. But during the 2 previous labs, most of you observed that diastolic pressure stayed the same or even decreased. one possible explanation
a) total peripheral resistance decreased because arterioles dilated
b) abdominal pressure decreased as blood was diverted to muscles
c) thoracic pressure decreased because brochioles dilated
d) stroke volume decreased to compensate for increased heart rate
