In an unusual population of humans (we’ll call thempressurites), blood pressures tend to be much higher than normal,with systolic pressures averaging about 160 mm Hg, and diastolicpressures about 110 mm Hg. Probably because of this, pressuriteshave a high incidence of stroke. Your job is to begin to figure outwhat might be wrong.
You discover that heart rates, stroke volumes and heartsize are all normal. List two possible causes of high bloodpressure that these data eliminate? 2 pts
Their sodium intake and urine function seems normal. Whyis this relevant to high blood pressure? 1 pt
They show no evidence of high cholesterol, orarteriosclerosis. Why is this relevant to high blood pressure? 1pt
You calculate their total peripheral resistance, and itis higher than normal. Describe three possible causes of high totalperipheral resistance that are plausible, given the evidence. 3pts
Describe experimental tests for each of these threepossible causes of elevated total peripheral resistance, and whatdata would support or refute the potential cause you are testing. 3pts
