what would be the levels of ADH in overdhyrdration
ADH â low; 100 mOsm (urine). Yes, in overhydration, ADH would be very low and the cells of the collecting duct would be relatively impermeable to water and urea. Thus, the final urine would be dilute, having an osmolarity of about 100 mOsm.ldosterone is stimulated by decreased plasma sodium levels and increased plasma potassium levels. xxx Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.
