Document Summary
A condition of equilibrium or balance, in the body"s internal environment. The survival of our body cells is dependent on the precise regulation of the chemical composition of their surrounding fluid. The fluid inside body cells is known as intracellular fluid. The fluid inside body cells is known as extracellular fluid. Interstitial fluid, plasma, lymph, cerebrospinal fluid, synovial fluid, aqueous humor, vitreous body (all are extracellular fluid but are specific to the membranes) The existence and maintenance of a relatively constant environment within the body. The ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes. Values of variables fluctuate around the set point to establish a normal range of values. Set point: the ideal/normal/average value of a variable. Negative: reverses the change in the controlled condition. Any deviation from the set point is made smaller (resisted) Regulation of blood pressure, body temperature, blood sugar levels.
