The maximum reabsorption of water without the influence of ADH takes place at

Most water reabsorption (65%) takes place in the proximal convoluted tubules, part of the nephrons in the kidney. Water is reabsorbed by a process called osmosis;Solute reabsorption in proximal convoluted tubules promotes osmosis of water.  the diffusion of water from an area of high water potential to an area of low water potential through a partially permeable membrane. Conditional reabsorption of Na+ and water takes place in DCT. ADH is the influencing factor at DCT.
