Example of thermochemical reaction within human body includes formation of
glucose from starch, fats, proteins, and other sugars. Energy consumption per unit
of body weight decreases with size as the rate of heat loss to the environment
depends largely on the surface area of an organism in a given environment. Thus,
the interrelationship between environment and human body is a factor that determines health of humans due to thermochemical reaction.
1.3.2 Osmosis
Osmosis is a property observed with respect to solutions with semipermeable membrane. Osmosis is the net flow of solvent through a semipermeable membrane where
the solvent flows from lower concentration of solute to the higher concentration.
Cellular health is the cornerstone of health for humans. The cell membrane permits only water and very small molecules to pass through it. Osmosis plays a major
role in the gastrointestinal system of the kidneys to upkeep the health of a person.
The osmotic pressure is the pressure difference between the two sides of a semipermeable membrane that separates solution with different concentrations. Osmosis
is one of the reasons for the intracellular movement of body fluids within our body
that has direct interrelation with the environment.
Reverse osmosis (Fig. 1.13) is a process by which the solvent flows in the reverse
direction, through a porous membrane, to that of natural osmosis.
