In human physiology, extracellular<unk>  are distributed between the interstitial compartment (i.e. tissue) and intravascular compartment (i.e. plasma) in an approximately 75%-25% ratio.<unk><unk>  is the physiological concept that body<unk>  may collect in a<unk> " body compartment that isn't normally perfused with<unk> .<unk> -space<unk> shift is the mobilization of body<unk> to a non-contributory space rendering it unavailable to the circulatory system. The<unk>  space where bodily<unk> resides is the interstitial space, or the space filled with interstitial<unk> between the cells within the tissues. Extensive tissue swelling occurs when the<unk>  space fills with excess<unk>  known as edema. An example of severe<unk><unk>  is ascites, as seen in severe liver failure as a result of a low albumin level in the circulating blood.<unk>  space is also a term used to refer to, for example, the bowel with an ileus, and the collection of<unk> therein, usually post-operatively. The interstitial space could be considered to be a sub-section of the extracellular compartment. The distinction one could make is that<unk> in the interstitium is still readily available to either the intravascular or the intracellular compartments, in response to ionic changes, whereas that which is pooled in the bowel<unk>  space) is not so readily available. It is a recurrent clinical phenomenon requiring swift identification to minimize deleterious effects.<unk><unk>  takes<unk> away from the normal<unk> compartments and causes the patient to have hypovolemia.
