Question

The amount of water present inside human body cells is about( )
A. \(15\) litres
B. \(5\) litres
C. \(25\) litres
D. \(10\) litres

Answer

C

Solution

a)About\( 60\)% of human body weight is due to water and is mainly present within the cells of the body.
b)Intracellular fluid (within the cell) constitutes about \(2/3 \)of body water.
Eg-In a person weighing \(72Kg\), \(40 litres \)of fluid is present in the body out of which about \(25 litres \)of water is present in the intracellular region (within the cells).
Water present in the human body supports the metabolic reactions in the body.
All the enzymes act efficiently in presence of water. The salts like sodium and potassium which dissolves in the water act as a transporter. It helps in the transmission of the nerve impulse.
