Decide how the following conditions would affect the physiology of the Uinary System ADH causes the osmolarity of urine to O Increase O Decrease OStay the same

Reabsorption of most solute molecules from the proximal convolutedtubule is linked to the active transport of Na+ across thea. apical membrane and out of the cell.b. apical membrane and into the cell.c. basal membrane and out of the cell.d. basal membrane and into the cell.

All of the above „When the concentration of ADH increases the specific gravity of the urine decreases less water is reabsorbed by the nephron and collecting duct more urine is produced ) less urine is produced more salt is secreted by the nephron عدم إرسال كلمات المرور عبر نماذج Go ogle مطلفا. لم يتم إنشاء هذا المحتوي ولا اعتماده من قبل Go ogle الإبلاغ عن اساءة الاستخدام - شروط الخدمة - سياسة الخصوصية Google zilai

Renal aquaporins allow for: O A. Increased paracellular water movement OB. Regulated cellular water absorption in the proximal tubule O C. Regulated cellular water absorption in the Loop of Henle OD. Regulated cellular water absorption in the collecting duct OE. None of the above

Drugs that increase urine flow (diuretic drugs) are oftenemployed in the treatment of hypertension (high blood pressure)or other disease states. Three physiological categories of suchdrugs are ones that (i) function as loop diuretics, (ii) inhibitthe action of aldosterone, and (iii) block Na+ channels in thecollecting ducts. Explain why each of these categories wouldbe expected to increase Na+ excretion and urine flow. (Hint:Rereading the section on hormones at the end of Chapter 28might prove helpful.)

Do answer

Which substances are activly (primarly or secondary) vs passively transported from the filtrate. understand the NaCl pimp at basolatermembrane and how it create a concentration gradient to drive the trans[ort of other substances

A decrease in blood osmolality results ina. increased ADH secretion.b. increased permeability of the collecting ducts to water.c. decreased urine osmolality.d. decreased urine output.e. All of these are correct.

Which of the following best describes the changes between dilute (osmolarity 50mOsm/Kg) andconcentrated urine (osmolarity 1200mOsm/Kg)? a. Concentrated urine has more water than NaCl moleculesb. Concentrated urine has less water than NaCl moleculesc. Dilute urine has more NaCl than water moleculesd. Dilute urine has less water than NaCl molecules
