When homeostasis is not maintained, the patient is at risk for organ system dysfunction and even death. One of the primary mechanisms by which homeostasis is maintained is through regulation of body fluid within the different fluid compartments.

The human body regulates fluid and electrolyte balance by adjusting to internal and external stimuli to maintain homeostasis . The two fluid compartments in the human body are the extracellular and intracellular fluid compartments.

base — a molecule that can donate a hydroxide ion (OH - ) in chemical reactions. acid — a molecule that can donate a hydrogen ion (H + ) in chemical reactions. total body fluid — found in the intracellular space and one-third is in the extracellular space. homeostasis — the process by which the human body maintains balance by adjusting to internal and external stimuli.
