Final answer:
Infants have a higher percentage of total body water compared to adults, making them more susceptible to dehydration and water loss in diseases.
Step-by-step explanation:
Infants have a higher percentage of total body water compared to adults, which makes them more susceptible to certain conditions.
For example, infants can become dangerously dehydrated quickly if they experience vomiting or diarrhea, as their body mass is lower. In addition, infants are more prone to water loss in diseases like kidney disease and fever.
These factors make infants more vulnerable to imbalances in body water content.
