Question

Man does not live by food alone. Water is vital to human health and fitness. Although it is not a

nutrient as are carbohydrates, fats, proteins, vitamins and minerals. It is infact a key nutrient as

no life is possible without it. Whereas we can do for weeks without food, we cannot live without

water longer than a couple of days. Water approximates 60% of the body weight of human

adults. The total amount of water in a man weighing 70 kilograms is approximately a little over

40 litres. It is an excellent solvent-more substances are soluble in water than any other liquid

known so far. This makes an ideal constituent of the body fluids which sustain life-supporting

chemical reactions. It dissolves diverse metabolic wastes and helps drain them out of the body.

The no less important role of water is to distribute /dissipate the body heat efficiently, thereby

regulating the body temperature. Water accomplishes this role because it has thermal

conductivity ensuring rapid heat from one part to the other. Above all, water has a high specific

heat to raise the temperature of water and likewise much heat must be lost to lower it’s

temperature.

Drinking a lot of water is an inexpensive way to stay healthy. Even excess of water is harmless.Water therapy of drinking a litre or so the first thing in the morning is kidney-friendly. The water

regulation in the body is affected by the hypothalamus in two ways i.e. (i) by creating the

sensation of thirst which makes us drink water and (ii) by controlling the excretion of water and

urine. If water regulation fails, medical emergency ensues will be created.

Answer the following questions based on the above passage. [1x5 = 5]

a. Why does water prove to be the key nutrient for our health?

b. What role does water accomplish ideally and why?

c. How does water imply that it has high specific heat?

d. How can we say that water is kidney-friendly?

e. Suggest two ways the way water regulation in the body is affected by hypothalamus?​

Answer 1

Answer:

A. as water dissolves almost everything makes it important and more than that we can't live without water.

B.The no less important role of water is to distribute /dissipate the body heat efficiently, thereby regulating the body temperature as we are warm blooded it is important to maintain temparature.

C. as it regulates the body's heat we can tell so.

D. because water helps in cleansing our body. it regulates the kidneys to work properly.

E.regulation in the body heat is affected by the hypothalamus in two ways i.e. (i) by creating the sensation of thirst which makes us drink water and (ii) by controlling the excretion of water and urine.

if any mistakes sorry dear

hope it helps ya...
