To maintain proper condition in which the desired system works.

Explanation:

Homeostasis is property of the system to maintain almost constant condition in spite of varying variables.

All the cells and organisms require an optimum conditions to perform various tasks efficiently. Any deviation from these optimal condition reduces efficiency. There are so many variables which keep on changing causing deviation from these optimum conditions.

Homeostasis mechanisms acts as a buffer to correct this deviation and keep it as close to optimum condition as possible.

example on organism level:
homeostasis of blood pH
blood has a buffer system which maintains the pH by using dissolved #CO_2#.

example on cellular level
homeostasis of #Na^+# in cells
Neuronal cells maintain a strict gradient across the cell of #Na^+# so as to fire a action potential upon excitation
