Homeostasis is the ability of the body to <u>maintain</u><u> </u>a relatively <u>stable</u> internal environment<u>,</u><u>despite</u> of environmental <u>fluctuations</u><u>.</u>
Nature has blessed living organisms with an excellent self regulatory system which adjusts all the internal conditions of a body in a stable state that are necessary for organism's survival.
Homeostasis maintains the flow of ions, nutrients, energy, temperature and every aspect that is important for an organism's survival.
The most common way cells deal with hypertonic and hypotonic environments is by osmosis through their semi-permeable membrane. The cells attempt to neutralize the hypotonic or hypertonic environment by absorbing/releasing water from/to the more concentrated system.
