What percentage of body water is found intercellularly?

The correct answer indicates that approximately 70% of the body's water is found intracellularly, which means within the cells. This intracellular fluid is crucial for various cellular functions, including maintaining cell shape, facilitating biochemical reactions, and transporting nutrients and waste products.

Understanding the distribution of body water is essential in medical fields, especially in contexts such as fluid resuscitation and electrolyte management. The 70% figure represents the vast majority of the body’s water content, highlighting the importance of cellular hydration for overall health.

Other options reflect lesser percentages, which are incorrect in the context of human physiology. The actual percentage of water that exists intracellularly is a well-established fact based on anatomical and physiological studies, confirming that the majority of our body water is contained within our cells.
