Proximal tubule cells have large numbers of mitochondria and demand a great deal of oxygen. Explain why.arrow_forwardWhich of the following does not contribute to the high salt concentration in the interstitial fluid of the kidney medulla? (a) active transport of sodium from the upper part of the ascending limb (b) diffusion of salt from the ascending limb of the loop of Henle (c) reabsorption of salt from various regions of Bowmans capsule (d) counterflow of fluid through the two limbs of the loop of Henle (e) diffusion of urea out of the collecting ductarrow_forward
- Which 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.
