Explanation:
A simple approximation of the amount of water in a human body is 60 liters. Our bodies are composed of about 50-60% water, which is distributed throughout various tissues and organs, not just filled up like a glass. For example, the brain is composed of about 85% water, and water plays a crucial role in digestion, circulation, the functioning of the nervous system, temperature regulation, and flushing out bacteria and viruses. In terms of daily intake and output, an average adult will take in around 2500 mL of fluids and lose approximately the same amount through urination, evaporation, and breathing. Each day, we lose nearly 9 liters of water, which indicates the importance of hydration and regular water consumption.
