Water is the most important element for life. Although we could think that this statement is valid only for aquatic organisms, since water constitutes their habitat, the truth is that it is important for all living beings that inhabit planet Earth. In fact, all living things require water to fulfill their basic vital functions. For this reason, from Ecologista Verde we want to emphasize the importance of water, more precisely on the functions of water in living things. If this topic is of interest to you, we invite you to continue reading this interesting article.
Before learning what is the function of water in living things, we will start with the basics: what is water and what types exist. Water is a molecule that is made up of two hydrogen atoms and one oxygen atom. Among its peculiarities we can mention that the water is insipid, since it has no flavor, odorless, since it does not have an odor, and colorless, that is, without color. For its part, water in ecosystems can be present in three different states.
Curiously, during the water cycle, it undergoes a series of transformations and goes through the 3 states just described. Here you can learn more about The Water Cycle.
Now, water can be classified according to different criteria. Next, we will list the types of water according to their chemical characteristics:
On the other hand, water can also be classified according to the type of treatment it has received:
For more information, we encourage you to read this other post about the Types of water. Since we have learned some basic aspects of water, in the following sections we will develop the functions of water in the organism of living beings.
The water is essential in cells and tissues and the hydration of these gives consistency to the organisms, not only to the animals but also to the vegetal organisms and of other types. As an example, water in organisms is so important that the percentage of water in the human body is approximately 70%. In addition, it is the main component of blood, lymph and sap.
We recommend reading more about cells and tissues:
Water also allows living things monitor your body temperature. For example, when temperatures are high, organisms perspire, that is, they release sweat or water vapor from their interior, to cool their exterior and thus reduce body temperature and be able to continue fulfilling their vital functions as best as possible.
Some researchers call water universal solvent, since it has the ability to dissolve a large number of molecules. Thanks to this particularity, water is a conducive medium for the metabolic reactions of organisms to occur in it.
Another point that highlights what water is for is its biochemical function. Water is not only the medium where they occur metabolic reactions, but is also a participant in some of these reactions. To mention a few examples, water is the product of many reactions such as respiration and the substrate of other reactions such as photosynthesis. Likewise, water is key in the digestion of food.
The role of water as transport allows nutrients are incorporated from digestion that are distributed by blood, lymph and sap. Here you can read about the Nutrition Function: what it is and processes.
It also facilitates that waste is removed or toxins through urine. In this way, water enables the nutrition and purification of organisms so that they continue to function properly.
The synovial fluid, which is composed mainly of water, reduces the friction of the bones and works as a shock absorber of the joints. Too, tears, saliva and snot made up of a large percentage of water, they serve as a lubricant for the membranes and mucous membranes of many animals, including humans.
Now that you know better the functions of water in living beings, you will be able to better understand why it is so important to hydrate by drinking water and why water is important for living beings in general, but we also recommend you take a look at our article.
