(A) increases, (B) decreases, (C) has no effect on
_______ Diabetes mellitus _?_ the glucose transport maximum.
_______ Increasing atrial natriuretic peptide _?_ the volume of urine (rate of urine production mL/min)
_______ Increasing ADH _?_ the volume of urine.
_______ Decreasing ADH _?_ the osmolarity of urine.
_______ Increasing aldosterone _?_ the volume of urine.
1. diabetes mellitus has no effect on transport maximum. Transported maximum for glucose is around 375mg/min. If the glucose level's it is not reabsorbed and passed through urine due to which we find glucose in urine.
2. On increasing atrial natriuretic peptide the volume of urine increases. Atrial natriuretic peptide promotes sodium and water excretion resulting in diuresis.
ADH function - reabsorption of water at collecting duct by binding to the receptors of ADH present on collecting duct
3. On increasing ADH the volume of urine decreases due to formation of more concerntrated urine because of reabsorption of water.
4. On decreasing ADH the reabsorption at collecting tubule does not occur so that more water is excreted through urine resulting in decreased osmolarity of urine.
5. On increasing aldosterone there is retention of fluid due to increased reabsorption of sodium resulting in decreased volume of urine.
