How a decrease in blood flow to kidneys affects the renin-angiotensin-aldosterone system, sodium absorption, and blood pressure.

- Explain the role of renin-angiotensin - aldosterone pathway in restoring blood pressure and fluid balance. Include the stimulus for release, the pathway that is involved, and the physiological effects of angiotensin II and aldosterone. Answer should include: Identify stimulus/change that starts the pathway (i.e. Identify the direction of change IN BP or circulating fluid status) What happens in the juxtaglomerular cells? Clue: what stimulus causes the release of renin? Explain action of renin - what protein does it act on? What is it converted to? Which enzymes converts angiotensin 1 to angiotensin 2? What are the actions of angiotensin 2? Clue: stimulates adrenal context to produce what? And what effect does angiotensin 2 have on blood vessels? What causes reabsorption of Na into blood ? What effect does this have on blood volume? How is BP restored ?

Be able to clearly explain the hormone’s mechanism of action.arrow_forwardDiuretics cause sodium excretion. Sodium follows water. Therefore, diuretics lead to a reduction in volume (remember BP = heart rate x volume x blood vessel tone (SVR)). Since diuretics lower volume, they lower BP. When would diuretics be indicated?

- Explain the anatomical features that create high glomerular capillary blood pressure and explain why this blood pressure is significant for urine formation.arrow_forwardWhich one of the following statements is false?a. Blood pressure in the glomerular capillaries is greater than the osmotic pressure exerted by proteins in the plasma within the glomerular capillaries.b. If the osmotic pressure exerted by solutes in the peritubular capillaries is greater than the blood pressure in those capillaries, then water will be reabsorbed.c. Endothelial cells in glomerular capillaries are highly permeable, facilitating filtration of fluid into Bowman’s capsule.d. Constriction of the afferent arteriole is likely to reduce the volume of filtrate appearing in Bowman’s capsule.e. The efferent arteriole carries blood from the glomerular capillaries directly to the renal vein.0.5 pointsQuestion 2Your doctor calls with the results of your urinalysis and tells you that they found proteinuria, the presence of abnormal amounts of protein in your urine sample.
