<prompt> Maximum absorption of water takes place inProximal convoluted tubuleDistal convoluted tubuleCollecting ductLoop of Henle  <response>: 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.
