The average body water content for adults is 50%; for infants, it is___(1). This value reflects a relatively higher water content in the_(2) compartment of infants. Infants also show different concentrations of (3) in the ICF compared with adults. At age 2 years, the adult pattern of body water distribution is evident. At adolescence, females have a(n) (4) body water content than males because the volume of the (5) compartment changes as a result of (6)_ accumulation. Infants have greater difficulty maintaining fluid homeostasis than adults because of their (7) rates of fluid ingestion and output, large, insensible water losses through the (8), and large water gains from a high (9).Infants are also at greater risk for acid-base imbalance because of the very low ( 10 ) of the lungs and the immature functioning of the __(11) In old age, body water content usually (12), reflecting changes in the (13) compartment. Blood pH and osmotic pressure show (14) changes, but restoration of homeostasis after imbalances occur (15) with age. The elderly may become dehydrated if they fail to respond to (16) stimuli. They are also particularly subject to such diseases as (17) and (18), which lead to severe fluid, electrolyte, and acid-base imbalances. Because these imbalances become evident when the (19) is highest or lowest, both infants and the elderly are at the highest risk..
