Final answer:
The human body is comprised of about 60% water due to its critical involvement in many bodily functions such as metabolic processes, nutrient transport, temperature regulation, and protection and lubrication of tissues.
Step-by-step explanation:
Your body is made up of approximately 60% water because water is a vital component for numerous bodily functions. It is the medium in which most cellular activities occur, including metabolic reactions and the transport of nutrients and waste products. Water is polar, meaning it's an excellent solvent and plays a critical role in biological processes. Water helps in the digestion and circulation of nutrients, supports the nervous system, helps regulate body temperature, and flushes out bacteria and viruses. Additionally, it is also critical in protecting and lubricating your joints and other tissues. Without sufficient water, life as we know it would not exist, as our bodies would fail to carry out their essential functions.
