ROLE OF WATER IN OUR BODY

(1/3) > >>

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.
