Long-term regulation of blood pressure is affected by: Correct Answer: hormones, kidney function, blood volume, vascular smooth muscle and hypertension Overtime, and as people age, systolic blood pressure __________; contributing to problems and increased risk of ________ Correct Answer: increases; hypertension 5 Hormones regulating kidney function include: Correct Answer: AVP, Renin, Angiotensin, Aldosterone, ANP Data from the Framingham Heart Study showed systolic blood pressure ________; diastolic blood pressure _______ with age along with increased risk of _______ and ________ Correct Answer: increases, decreases; stroke and LV hypertrophy Left Ventricle hypertrophy is a result of _____________that increases with age; also increasing a persons risk for ______, _____, and _______ Correct Answer: chronic hypertension; HTN, CVD, Stroke ***Increased MAP is expected to: Correct Answer: Increase GFR - the main thing that drives Glomerular capillaries is pressure (increased GFR) Increase in Blood volume is expected to increase _____,________, and _______ Correct Answer: Blood Pressure, Venous Return of blood to the heart, and Cardiac Output ----Increased CO also increases total peripheral resistance and increased arterial pressure =Increased GFR = increased urine output via Correct Answer: Autogenic regulation or "Myogenic Regulation" Pressure Diuresis: Correct Answer: a rise in BP normally causes an increased production of urine -acts to return blood volume to a lower value -increased pressure of blood in glomerular capillaries = increased GFR = increased urine excretion (double production of urine) Pressure Natriuresis: Correct Answer: -increase sodium excretion with increased water excretion during pressure diuresis -increased MAP increases GFR (increase in sodium excretion from increased blood pressure) To correct both BP and HTN - you need to lower both BV and BP by excreting both Correct Answer: Water and Sodium thru the urine
