Chapter 20.2, Problem 6CC
Summary Introduction
To determine: The reason for excretion of a greater volume of urine in the patients taking a loop diuretic.
Introduction: Diuretics are also called “water pill.” These facilitate kidney to excrete unused water and salts from the body. Diuretics help the heart to pump blood efficiently. These are generally prescribed to patients having a heart and kidney disorder.

Are any of these substances abnormal in urine? Explain.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
- 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_forwardDescribe the effect of ADH on renal collecting tubules.arrow_forwardWhich of the following does not contribute to the process of filtration? (a) active transport by epithelial cells lining renal tubules (b) large surface area for filtration (c) low permeability of glomerular capillaries (d) high hydrostatic blood pressure in glomerular capillaries (e) podocytesarrow_forward
- How Did The Addition Of Aldosterone Affect Urine Volume(compared with baseline)? Can the reabsorption of solutes influence of water reabsorption in the nephron? Briefly explain.arrow_forwardExplain why exercise increases the urea concentration in urine.arrow_forwardDrugs that increase urine flow (diuretic drugs) are often employed in the treatment of hypertension (high blood pressure) or other disease states. Three physiological categories of such drugs are ones that (i) function as loop diuretics, (ii) inhibit the action of aldosterone, and (iii) block Na+ channels in the collecting ducts. Explain why each of these categories would be expected to increase Na+ excretion and urine flow.arrow_forward
