- 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?Which 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) podocytesJames experienced unexplained weight loss, fatigue, and lowblood pressure. After running several tests, his physicianconcluded that James had Addison disease, which involvesdecreased aldosterone production by the adrenal gland. When aldosterone production falls too low, certain kidney cells are unable totransport Na+ back into the blood.Predict 51) How does Addison disease affect Na+levels in the urine?2) Would you expect James’s urine volume to be higher or lowerthan normal? Explain your answer.
- which of the following is a response to the release of antidiuretic hormone? a. urine volume increases b. positive feedback occurs leading to the release of more ADH c. water reabsorption increases at the collecting duct d. blood osmolarity increasesWhich of the following is, are function of the kidneys? a. Control plasma volume b. Control blood pressure c. Control red blood cell production d. All of thesea pt has hyperthyroidism and his Na+/K+ ATpase pumps are working slower. Will this effect the transport of Na+? A. There will be a reduction in Na+ transport on the basolateral side of the tubule epithelial cell. B. there will be a reduction in Na+ transport in bowmans capsule epithelial cells C. there will be no change to Na+ transport D. there will be a reduction in ATP-dependent, Na+transport on the apical side of the tubule epithelial cells E. there will be a reduction of Na+ secretion on both sides of the tubule epithelial cells
- Acetazolamide is a diuretic that blocks the activity of the enzyme carbonic anhydrase inside kidney tubule cells. This blockage prevents theformation of carbonic acid from CO2 and water. Normally, carbonicacid dissociates to form H+ and HCO3−, and the H+ is exchanged forNa+ from the urine. Blocking the formation of H+ in the tubule cellsblocks Na+ reabsorption, thus inhibiting water reabsorption andproducing the diuretic effect. With this information in mind, what effectdoes acetazolamide have on blood pH, urine pH, and respiratory rate?(a)Reabsorption of water from distal parts of the tubules is facilitated by hormone_______.(b) Dialysis fluid contain all the constituents as in plasma except _______.(c) A healthy adult human excretes (on an average) _______ gm of urea/day.In the renin-angiotensin-aldosterone mechanism,________.a. decreased blood pressure prompts the release ofrenin from the liverb. aldosterone prompts increased urine outputc. aldosterone prompts the kidneys to reabsorbsodiumd. all of the above
- Antidiuretic hormone (ADH) is produced in the pituitary gland and regulates the body's fluid volume and osmolality by affecting the number of active aquaporins (water channels) in the proximal tubules and the collecting duct. But what is it, above all, that drives the filtrate out of the tubules? a) Osmotic pressure formed depending on the composition of the filtrate b) Osmotic gradient in the medullary (kidney marrow) c) Hydrostatic pressure from the filtrate in tubules d) Blood pressure in the capillaryWhich of these is not a function of the kidneys? A) The kidneys regulate the plasma volume B) The kidneys help to regulate blood pressure C) The kidneys help control the rate of red blood cell production D) The kidneys deactivate vitamin D and stimulate the activity of osteoclastswhen atrial natriuretic peptide is injected into an experimental animal, which of the following is an acute physiologic response? A. decreased blood pressure B. decreased heart rate C. increased renin release D.increased sodium and water reabsorption by the kidney . E, systemic vaso
