Approximately what percentage of the human body is composed of water?

The human body is approximately composed of 60% water. This percentage can vary slightly depending on factors such as age, sex, and body composition. In general, adult males typically have a higher percentage of body water compared to adult females due to differences in muscle mass and fat distribution.

Water plays a crucial role in various physiological processes, including temperature regulation, nutrient transport, and waste removal. Understanding the significance of water in the body’s composition helps appreciate its vital functions in maintaining homeostasis and overall health.
