I think it is about 70%
total body water decreases with age, and restoration of homeostasis is slower
Plasma Osmolarity =Total Body mOsm - Urine mOs-------------------------------------Total Body Water - Urine Volumeand: Total Body Osmolarity = PLasma Osmolarity x Weight x 0.6 Total Body Water = Weigth x 0.6
Why are infants susceptible to significant losses in total body water ?
yes their body temperatures are no different that adults.
60%
Adults lose nearly two to three quarts (12 cups) of water every day.
80%
Water (and its up to 70 % in health adults and 80 % in infants).
About 60 percent of an adult human male's total body weight is water
About 55 percent of an adult human female's total body weight is water
About two-thirds of the body's weight. This decreases with age, beginning at about 75% for babies and reaching around 60% in adults.
Adults need to drink eight to ten glasses of water per day
