Compared to adults, the water percentage in infants is...

• A. Higher
• B. Lower
• C. The same
• D. Unpredictable

Answer: (A)

Infants have a significantly higher percentage of body water compared to adults. On average, an infant's body is composed of about 75-78% water, while in adults, this percentage typically ranges from about 50-65%. This higher water content in infants is crucial for their growth and development, as water plays a vital role in numerous physiological functions, including temperature regulation, nutrient transport, and metabolic processes. The increased water percentage in infants is primarily due to their smaller body mass and the rapidly developing physiological systems that require a higher volume of water. Additionally, infants have a higher metabolic rate than adults, further emphasizing the need for adequate hydration. This characteristic of infants is important because it means they may be at a greater risk for dehydration compared to adults, especially when faced with illness or inadequate fluid intake. Understanding the significance of this higher water percentage helps caregivers ensure that infants receive adequate hydration for their health and development.
