(a) Ascending limb of Henle’s loop is impermeable to water whereas the descending limb is permeable to it
→ That's because the loop has a sharp bend in the renal medulla going from descending to ascending thin limb.
(b) Reabsorption of water from distal parts of the tubules is facilitated by hormone vasopressin.
→ Vasopressin allows more water reabsorption and excretion of more concentrated urine.
(c) Dialysis fluid contains all the constituents as in plasma except nitrogenous wastes.
(e) A healthy adult human excretes (on an average) 25-30 gm of urea per day.
