Small ions in biological fluids
WebTranscellular fluid is the portion of total body water contained within the epithelial-lined spaces. It is the smallest component of extracellular fluid, which also includes interstitial fluid and plasma. It is often not calculated as a fraction of the extracellular fluid, but it is about 2.5% of the total body water. Web2 days ago · The K+ ion concentrations in most animal cells range from 0.12 to 0.16 mold-3 while Na+ ion in the same cell does not exceed 0.01 mol dm-3. The ratio in the extracellular fluid is reserved. Thus, there is a considerable gradient of concentrations of Na+ and K+ ions between the two cellular ions.
