Answer:
Acting as an energy source for the body
Explanation:
Water is not a source of energy for the body, but if you do not drink enough water your body will become dehydrated and may experience symptoms of lack of energy.
Water represents about 60% of the total body weight of an adult and almost 80% of a child's body. It is the main component of our cells, but is also found outside these structures (extracellular fluid). Among the cells that present more water, those located in the muscles and the viscera stand out.
Water is a powerful solvent and is related to virtually every reaction in our body, since these reactions happen in aqueous media. It also acts on physiological processes, such as digestion, being part of important substances - gastric juice, for example.
Water is fundamental for the transport of substances such as oxygen, nutrients and minerals, as it is part of the composition of blood plasma. In addition to bringing nutrients to cells, water provides the elimination of substances out of the body. This is the case of urine, which is basically made up of water and dissolved or excess toxic substances.
We should also mention the role of water in regulating body temperature. When the heat becomes exaggerated, the release of sweat, which has water in its composition, begins. Upon contact with the medium, sweat evaporates on the surface of the skin, causing the body to cool.
