ROLE OF WATER IN OUR BODY

[nahidanfe]

1.Water is more important than food. It is found as intracellular fluid and also around organs as extracellular fluid and between the cells as inter cellular fluid of the body.All the constituents of protoplasm are suspended in water . It is a structural component . It cushions all cells . 0.4g water is found per g of protein ,while 0.2g water is found per g of fat .In some tissues such as bone it is tightly bound but in most cells there is a constant interchange of ICF and ECF in order to maintain osmotic pressure.Turgidity of tissues and cells is due to the water content .

2.It acts as a solvent in all stages of digestions.We feel more thirsty    after a meal .

3.It keeps nutrients in solution form so that they may be absorbed through the intestinal walls .

4.It transports nutrients through blood to all the tissues .

5.It acts as vehicle for the waste products which are excreted either through the bowels or through the kidneys .

6.It is a lubricant and prevents frictions between the moving parts .Saliva in the mouth helps us in swallowing food .The fluids around joints ,mucosa secretions of the gastrointestinal tract , the genito-urinary and respiratory tracts are some other examples.

7.Water regulates body temperature through evaporation from the lungs and skin . It's cooling effect is necessary to get rid of metabolic heat generated in the body .Each litter of water lost through perspiration represents a heat exchange of about 600kcal.

The general recommendation is 8x8 oz cups of water daily. Some say you need more. But some say drinking too much will get you water intoxicated.Thanks sir for your informative post.

Functions of water in human body

Water provides a balance in the body – homeostasis. It provides an absorption of the water-soluble substances, transportation of the nutritive to the target cells and the excretion of waste products of the metabolisms of the body.

Recommended daily amount (litres/day)

- children – 1.3-1.7

- men – 3.7

- women – 2.7

- pregnant women – 3.0

- lactating women – 3.8

Sources

All beverages include a water. Amount of water in the food – especially lot of water contain: water-melons, melons and other fruits, soups etc.

Negative consequences of over ingestion

There are no maximum doses. Healthy and fully operating kidneys theoretically can filter up to 0.7 litres of water in one hour, that is almost 17 litres of water a day. However excessive ingestion of water and other liquids is extra work for the body. Signs of intoxication of water are hyponatriemya (decreased amount of natrium in blood) and rubdomiolysis (damage of muscularity – collapse of skeleton) what can cause acute incompetence of kidneys.

Notes

Stated recommended daily amounts are given for inhabitants of the moderate climate. If the humidity is considerable, temperature, physical or emotional load and other side factors, use of water can be higher. Also it must be considered that average amount of water ingested by food is only 20% of recommended daily amount.
