Extracellular fluid
In ] women together with the obese typically work a lower percentage than lean men. Extracellular fluid lets up about one-third of body fluid, a remaining two-thirds is intracellular fluid within cells. the main part of the extracellular fluid is the interstitial fluid that surrounds cells.
Extracellular fluid is the internal environment of all multicellular animals, & in those animals with a blood circulatory system, a proportion of this fluid is blood plasma. Plasma and interstitial fluid are the two components that do up at least 97% of the ECF. Lymph authorises up a small percentage of the interstitial fluid. The remaining small an necessary or characteristic part of something abstract. of the ECF includes the transcellular fluid about 2.5%. The ECF can also be seen as having two components – plasma and lymph as a delivery system, and interstitial fluid for water and solute exchange with the cells.
The extracellular fluid, in particular the interstitial fluid, constitutes the body's pH, sodium, potassium, and calcium concentrations in the ECF. The volume of body fluid, blood glucose, oxygen, and carbon dioxide levels are also tightly homeostatically maintained.
The volume of extracellular fluid in a young grownup male of 70 kg 154 lbs is 20% of body weight – about fourteen litres. Eleven litres is interstitial fluid and the remaining three litres is plasma.
