- As the text noted, two-thirds of the water and solutes that the body reclaims by reabsorption in nephrons occurs in the proximal tubule. Proximal tubule cells have large numbers of mitochondria and demand a great deal of oxygen. Explain why.arrow_forwardFigure 41.6 Which of the following statements about the nephron is false? The collecting duct empties into the distal convoluted tubule. The Bowman’s capsule surrounds the glomerulus. The loop of Henle is between the proximal and distal convoluted tubules. The loop of Henle empties into the distal convoluted tubule.arrow_forwardDescribe (and label on a diagram) the structures of a nephron (including associated blood vessels) and give the functions of each structure.arrow_forward
- Water and small solutes enter nephrons during ________. a. filtration b. reabsorption c. secretion d. both a and barrow_forwardWhy is excretion important in order to achieve osmotic balance?arrow_forwardFatty tissue holds the kidneys in place. Extremely rapid weight loss may cause this tissue to shrink so that the kidneys slip from their normal position. On rare occasions, the slippage can put a kink in one or both ureters and block urine flow. Suggest what might then happen to the kidneys.arrow_forward
- As a person ages, nephron tubules lose some of their ability to concentrate urine. What is the effect of this change?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_forwardWhich of the following is an example of autoregulation of kidney function? a. The RAAS regulates Na1 by secreting renin when blood pressure or blood volume decreases. b. The ADH system regulates water balance by decreasing water reabsorption and increasing excretion of salt. c. Receptors in the juxtaglomerular apparatus detect a higher salt concentration in the distal convoluted tubule and trigger constriction of the afferent arteriole to reduce glomerular filtration rate. d. ANF is released by the kidney to increase renin release. e. Angiotensin II lowers blood pressure by constricting arterioles.arrow_forward
- which of the following correctly shows the order in which the filtrate moves through the structures of the nephron? a. proximal tubule - distal tubule - collecting duct - loop of Henle b. collecting duct - loop of Henle - proximal tubule - distal tubule c. distal tubule - loop of Henle - proximal tubule - collecting duct d. proximal tubule - loop of Henle - distal tubule - collecting ductarrow_forwardA nephron does not include: a. Aferent and eferent arterioles b. Cortex and medulla regions c. Bladder and ureter d. Loop of Henlearrow_forwardWater moves out of the filtrate of the descending limb of the nephronloop becausea. there is a high concentration of solutes in the surrounding fluid.b. the cells of the descending limb are permeable to ions.c. the difference in the diameter of the arterioles creates a pressuregradient.d. there is a high concentration of solutes in the descending limb.arrow_forward
