Step by step
Solved in 2 steps
- Figure 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.Water and small solutes enter nephrons during ________. a. filtration b. reabsorption c. secretion d. both a and bFatty 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.
- 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.Reabsorption depends on _________. a. osmosis across the nephron wall b. active transport of sodium across the nephron wall c. a steep solute concentration gradient d. all of the aboveBlood pressure forces water and small solutes out of blood and into nephrons during ________. a. glomerular filtration c. tubular secretion b. tubular reabsorption d. both a and c
- Figure 41.8 Loop diuretics are drugs sometimes used to treat hypertension. These drugs inhibit the reabsorption of Na+ and Cl- ions by the ascending limb of the loop of Henle. A side effect is that they increase urination. Why do you think this is the case?Why would efferent arterioles are constricting more than they should cause some to urinate more than usual. efferent arteriole constriction decreases blood pressure in the glomerulus, which increases filtration rate efferent arteriole constriction increases blood pressure in the glomerulus, which increases filtration rate efferent arteriole constriction relaxes the muscle in the bladder that prevents urination efferent arteriole constriction increases blood pressure in the glomerulus, which decreases filtration rateWhich row below indicates a MISMATCH between the processes and the functions of the kidney? Row Process Function excretion of metabolic wastes rids the body of urea and uric acid maintaining the water-salt balance helps regulate blood volume maintaining the acid-base balance rids the body of nitrogenous wastes regulating salt balance in the blood reabsorption of various ions including Na+
- The main function of the long nephron loops is to ______. help maintain a constant solute concentration throughout the kidney increase the solute concentration in the renal medula maximize the concentration of NaCl in the distal convoluted tubule remove glucose and other nutrient molecules that are not reabsorbed in the proximal convolutedDiuresis is increased urinary excretion. 2-3 cups of coffee has a diuretic effect, most likely because it causes vasodilation of the afferent glomerular arteriole which leads to a change in glomerular filtration rate (how quickly/how much filtration is occurring). It also appears that caffeine has a natriuretic effect on the nephron, leading to decreased NaCl reabsorption. (from Rang et al., 2016; p594 & Shirley et al., 2002) Considering that information, describe the effects that Lacy's coffee consumption had on her hydration statusWhich of the following statements concerning the medullary verticle osmotic gradient is TRUE: W. The loops of Henle of juxtamedullary nephrons establish a medullary osmotic gradient by means of countercurrent multiplicationX. The vasa recta enable the medulla to be supplied with blood while conserving the medullary osmotic gradient Y. The medullary osmotic gradient permits excretion of urine of differing concentrationsZ. The collecting tubules of all nephrons descend through the medullary osmotic gradient before emptying into the renal pelvis Select one: a. if only W, X and Y are correct b. if only W and Y are correct c. if only X and Z are correct d. if only Z is correct e. if all are correct
