Why Are We Made Of Water, Anyway

Why are we made of water, anyway?

Human body cells would perish. Without water, none of the vital bodily processes—such as breathing, digestion, and muscle movement—could occur. Coincidentally, more than 70% of the Earth’s surface is covered in water, as is the human body, which contains about 70% water. The longest the body can survive without food or water is believed to be about one week. However, if all it has is water and nothing else, it may last up to two or three months.Without drinking a sufficient amount of water, you won’t survive very long. Only a few days can be spent without water. Depending on a number of variables, you might be more susceptible to the effects of dehydration sooner.Generally speaking, a person can live without water for about three days. The amount of water a particular body needs and the way it uses water, for example, can have an impact on this. Age is one factor that may alter a person’s water requirement.

What are people made of?

Only six elements make up the majority of the human body: oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. About 0. More than 99 percent of the atoms inside you are made up of the four most prevalent elements in the human body: hydrogen, oxygen, carbon, and nitrogen. They are present in all parts of your body, mostly as water but also as parts of biomolecules like proteins, fats, DNA, and carbohydrates.Your body is composed primarily of hydrogen, carbon, nitrogen, and oxygen atoms, which make up about 99 percent of it. The other elements necessary for life are also present in much smaller quantities in you.Among other elements, our DNA contains phosphorus, nitrogen, oxygen, and carbon. Except for hydrogen, which has been present since shortly after the big bang, all of those elements are produced by stars and released into the universe when they die.Atoms of hydrogen, carbon, nitrogen, and oxygen make up nearly all of your body. The other elements necessary for life are also present in you, but in much smaller amounts.
