- 32. Jim was standing at a urinal in a public restroom and a long line was behind him. He became anxious (a response of the sympathetic - "involuntary" - nervous system) and found he could not urinate no matter how hard he tried. Use logic to deduce Jim's problem. a) his internal urethral sphincter was constricted and would not relax b) his external urethral sphincter was constricted and would not relax c) his detrusor muscle was contracting too hard d) he almost certainly had a burst bladder.Which 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 ascendinglimb of the loop of Henle (c) reabsorption of salt from various regions of Bowman’s capsule (d) counterflow of fluid through the two limbs of the loop of Henle (e) diffusion of urea out of the collecting duct35. The starting point (X) on the graph represents a person who had been drinking water ad libitum. Which of the following lettered arrows indicates the change that will occur 60 minutes after drinking 1 L of distilled water? OA) 1200- Urine osmolality mOsm/Kg H₂O 900- 600- 300- A E B) B -2 2 D C 4 6 Urine flow rate mL/min C) 8 O D) 10 E)
- The voiding reflex allows the sensation of the urge to urinated but prevents uncontrol urination by A stimulating parasympathetic stimulation of the detrusor muscle B inhibiting somatic nerves to the external urethral sphincter inhibiting parasympathetic stimulation of the detrusor muscle D inhibiting sympathetic stimulation of the internal urethral sphincter E) stimulating somatic nerves to the external urethral sphincter1.8 Which of the following is likely to cause the kidney to change the reabsorption of water and/or NaCl? Select one: a. Drinking 1 L of water in a short period of time. (Assume that you weren't dehydrated.) b. Eating a big bag of salty potato chips. c. Forgetting to drink water all day. d. Exercising vigorously in a very hot environment. e. All of the above1) If the excretion of a substance is less than the filtration rate, the substance must be just secreted filtered and secreted filtered and reabsorbed just filtered, secreted, and reabsorbed 2) In the absence of vasopressin, what would happen to the urine concentration?a. It would be concentratedb. It would be dilutec. Vasopressin has nothing to do with urine concentration 3) Blood going from systemic veins through the right ventricle is _________a. high in 02 and high in CO2b. low in hemoglobinc. high in hemoglobind. low in 02 and high in CO2e. low in 02 and low in CO2
- Parasympathetic stimulation of the bladder causes (a) inhibition of the detrusor muscle and relaxation of the external urethral sphincter, (b) contraction of the detrusor muscle and relaxation of the internal urethral sphincter, (c) relaxation of the internal and external urethral sphincters, (d) contraction of the detrusor muscle and contraction of the internal urethral sphincter.1. What would be the influence of decreasing reabsorption of sodium on urine volume?38. The cystometrogram was obtained by measuring the pressure within the urinary bladder of a healthy man during infusion of sterile water into the bladder. Increased firing rate of parasympathetic fibers and decreased firing rate of motor fibers in the internal pudendal nerve occur most often during which of the following intervals? OA) V to W OB) W to X OC) X to Y OD) Y to Z Pressure om H₂0 30- W 100 N 200 300 Volume (ml) Vesm 400 500
- 9. Explain the physiological basis for the effect of atrial natriuretic peptide (hormone) on urinary volume output .Drugs 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.3. Administration of a drug that inhibits Na+ reabsorption by the thick ascending limb of the loop of Henle results in which of the following? OA) Decreased ability to excrete maximally concentrated urine OB) Decreased K+ excretion C) Decreased Na+ reabsorption by the collecting duct OD) Increased fluid reabsorption by the proximal tubule. OE) Increased urea reabsorption by the collecting duct
