- Which of the following is TRUE concerning renal handling of potassium? a. A high potassium meal will cause enhanced basolateral uptake via sodium-potassium pumps b. Most potassium reabsorption occurs at the distal tubules c. Aldosterone enhances potassium reabsorption at the proximal tubule d. Potassium is not filtered, so urinary excretion of potassium will only occur by stimulating potassium secretion e.

- Find which of the following statements about medulary collecting duct is TRUE A. Its permeability to water is controlled by aldosterone B. It is impermeable to ureaC. Its permeability to water is controlled by ADHD. It is incapable of secreting H+ against large concentration gradientarrow_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.
