Water is the largest part of the body with 55 to 75% of the human body being comprised of primarily water. Blood, digestive juices and the lubrication for joints are all essentially composed of water. As a result, we see that the body cannot function without water. Additionally, since the body is not designed to store water, a fresh supply needs to be provided to it on a daily basis. Here are some of the functions of water outlined to help explain why it is an element that one simply cannot do without.
Each and every cell in the body needs water to be able to survive. One of the primary functions of water is to carry the necessary nutrients and minerals like glucose to the cell which they need to carry out the required reactions to provide the body with energy. Water also works by carrying away the waste products away from the cells after the reaction.
All the waste products that come about as a result of the function of the organs and the cells are removed from the body with the help of water. These waste products can be really harmful and actually poison the body if left inside. Water helps flush out thee toxins by using several mediums such as perspiration, urine and feces.
One of the most important functions of water is the maintenance of our body’s temperature. Without water, humans would not be known as warm blooded animals because the temperature of the body and blood would never remain at this constant level it does now. Due to the fact that it has a large heat capacity, water absorbs most of the temperature changes in itself and makes sure the body doesn’t lose or gain too much heat when it’s surrounding environment changes. For example, if the body gets too heated up, water allows it to effectively lose the extra heat. Sweating occurs and the evaporation of sweat from the body surface has an instant cooling down effect which brings the body temperature back to normal.
The lubrication around joints is also made up of primarily water. As a result, another function of water is to make sure that the joints are not harmed or affected by the shocks of everyday life. These shocks are absorbed by the protective layer of water. Water also serves as a medium to prevent shocks getting through to the spinal cord and the eyes. Not only that, but the unborn fetus is also surrounded by amniotic liquid which is made up of water. This water helps to prevent damage and provide nutrients to the baby.
Water makes up the missing bulk in our everyday diet. This in turn helps to move the consumed matter around the digestive system at a faster pace which results in a healthy and regular stool with constipation being avoided. Common causes of constipation do infact include too much water being absorbed from the diet.
