Acid base balances and Arterial blood gas

Different kinds of biological fluids exist within the human body. These can be found in the intracellular and extracellular fluid compartments, respectively. Plasma is stored in the vascular compartment. Interstitial (including lymphatic), cerebral, pleural, pericardial, and gastrointestinal fluids are all included in the extravascular compartment. All body fluids have critical …
