Water

In a healthy adult male 60% of bodyweight is water, females have proportionately more body fat than males and the total body water is about 55% of bodyweight

65% of the total body water is inside the human cells, which we call the water now the intracellular fluid. The rest which is 35% outside the cells we call it the extracellular fluid. and it divided into intravascular water which run in our vessels with the blood, and interstitial water, which is water between the cells.

Every day we lose water from our bodies by many ways, the urination is the main way to lose water, another is the by skin, we lose a small amount of water when we sweat. Some water vapor comes out from the lung when we breathe. And finally we lose a tiny amount of water in the stool.

To balance this waste, we supply our bodies with water, by drinking water and water from the moist food. Few amounts of water, the body makes them via the metabolisms.

And this list for the water functions in the human body:

1. •Transports nutrients and oxygen into cells2. •Maintain the health and integrity of every cell in the body3. •Moisturizes the air in lungs4. •Keep the bloodstream liquid enough to flow through blood

vessels5. •Regulate body temperature through sweating.6. •Help eliminate the by-products of the body’s metabolism,.7. •Lubricate and cushion joints8. •Keep mucous membranes moist, such as those of the lungs

and mouth.9. •Aid digestion and prevent constipation.Reduce the risk of

cystitis by keeping the bladder clear of bacteria.10. •Work as a moisturiser to improve the skin’s texture and

appearance.11. •Serve as a shock absorber inside the eyes, spinal cord and in

the amniotic sac surrounding the fetus in pregnancy.

Dehydration:1. •Increased sweating due to

hot weather, humidity, exercise or fever.

2. •Not drinking enough water.

3. •Increased output of urine due to a hormone deficiency, diabetes, kidney disease or medications.

4. •Diarrhea or vomiting. Especially in kids.

5. •Recovering from burns.

•Dark Urine – Dark Yellow. .•Dry Skin.•Thirst•Hunger:.•Fatigue: •Tiredness•Migraine

•Constipation•Muscle cramps•Irregular blood pressure•Kidney problems•Dry skin•20% dehydrated – Risk of death
