What role does water play in the human body?

There are three main effects of water on human body: it plays an important role in the formation of human tissues. Water in human body is collectively called body fluid, which is concentrated in cells, tissues and various pipelines, and is an important substance that constitutes cells, interstitial fluid, plasma and so on. Supplement nutrition and participate in various metabolism of the body. There are many rich minerals in drinking water, such as calcium, magnesium, iron, copper, chromium, manganese and other elements. Appropriate content of these elements is beneficial to human health. At the same time, water can also help the body digest food, absorb nutrients, eliminate waste, participate in regulating acid-base balance and body temperature in the body, and play a lubricating role among organs. The media function of traffic. As the medium for all chemical reactions in the body, water is the medium for transporting various nutrients and substances. Because the human body contains a lot of water, the heat energy generated during metabolism is absorbed by water, so the body temperature will not increase significantly; In fact, the evaporation value of water is very large, and the heat of vaporization per milliliter of water is about 579.5 kcal (37 "). Therefore, the human body can emit a lot of heat by evaporating a small amount of water to maintain a certain body temperature. If the external environment temperature is high, you can use water to evaporate the body heat through the skin to maintain a constant body temperature.
