C. The normal daily insensible water loss is 600 to 900 ml.

E. In normal humans, urine represents the greatest source of daily water loss.

DISCUSSION: The skin is the primary source of insensible water loss. Including losses from the lungs, this averages 600 to 900 ml. per day. Catabolism liberates “water of solution.” In normal humans, urine represents the greatest source of water loss. The patient deprived of external access to water must still excrete a minimum of 500 to 800 ml. of urine per day to expel the products of catabolism.
