John, an overweight, sedentary, 58-year-old man, was diagnosed with hypertension (high blood pressure). Changes in in lifestyle, including regularexercise and a healthier diet, were very effective in reducing his hypertension. He is also on a low dose of an antihypertensive medication calledangiotensin converting enzyme inhibitor (ACE inhibitor). This medication inhibits the activation of angiotensin I. What are the main mechanisms ofaction of angiotensin Il that lead to an increase in blood pressure? How does angiotensin I affect the kidneys?

During a routine medical checkup. Candice, a 26-year old physiotherapy student, is surprised to hear that her blood pressure is 180/110. She also has a rumbling systolic and diastolic abdominal murmur that is loudest at the mid-epigastric area. Her physician suspects renal artery stenosis. She orders an abdominal ultrasound and real artery arteriography, which confirm that Candace has a small right kidney and the distal part of her right renal artery is narrowed by more than 70%. Her physician prescribes diuretics and calcium channel blockers as temporary measures refers Candace to a cardiovascular surgeon. a) How will diuretics and calcium channel blockers improve her hypertension and abdominal murmur? b) Explain the connection between Candace's renal artery stenosis and her hypertension.
