Final answer:
The human body is made up of about 50-60% water, which is distributed across various fluids inside and surrounding bodily cells and tissues, essential for physiological functions.
Step-by-step explanation:
The percentage of the body made up of fluid is significant. In adults, water makes up about 50-60% of body weight, though this can be as high as 70% in some cases. This percentage of water is crucial as it is distributed throughout the body and contributes to various functions, serving as a major component of both intracellular and extracellular fluids. It is essential for numerous physiological processes, including acting as a lubricant and cushion for the body's tissues and organs.
