Maximum absorption of water takes place in
Ascending limb of the loop of Henle and an early segment of distal tubule is impermeable to water. Maximum of filtered water (60-70%) is reabsorbed in the proximal tubule, with or without Vasopressin. This is independent of the fluid and electrolyte status of the body.
