What is the Extracellular Fluid?

"what-is-the-extracellular-fluid"

 

Water or fluid is an essential thing for our body. To stay healthy as well as hydrate our body requires a good amount of fluid or water. It assumed that, of overall our body weight almost 60 percent is water weight and 40 is another weight. From this ratio, it is somewhat clear that how much importance fluid or water generally carries to run our body system. Therefore, again, this 100 % total body water (TBW) usually goes proportionately in two major compartments of the body. One is called Extracellular and another is an Intracellular compartment.

 

Extracellular Fluid

 

The term “Extracellular fluid “usually refers all the body fluid which stays outside the cells. That means, it consists of tissue fluid, blood plasma, and some other fluid like- lymph, which occurs outsides of the cells. And the part which stays inside the cells is called intracellular fluid. There is a constant exchange of gasses and other materials between intracellular and extracellular fluid. The volume and the composition of the Extracellular have to remain stable for these exchanges to occur. Anyway, urinary system is accountable for maintaining relatively stable condition in the ECF or Extracellular fluid. The extracellular fluid which is one of two major compartments is equally accounted for overall body weight or total body weight in short (TBW). Unlike intracellular, it has two major sub-compartments such as- interstitial and blood plasma. These two make up almost 97 % of extracellular fluid together and rest is made up of Transcellular fluids which also comprises nearly 2.5 % of it. There is also an inclusion of a portion of lymph by the necessary logic of the outside of the cells definition, despite lymph is neglected in the extracellular fluid (ECF) discussion. So you can say, Extracellular fluid (ECF) is comprised of tissue fluid, blood plasma and other fluids like lymph what usually occurs outside the cells. Following a single way, ECF can be followed. The way to view the ECF is such that it has two components i.e. Plasma and lymph work as a delivery system. And the interstitial fluid works for solute exchange.

 

However, the internal environment, which usually bathes all the cells of body is constituted by the interstitial portion of the extracellular. Hence, the composition of Extracellular fluid is very important for their function. A set of hemostats is usually used which keep the pH, the potassium(K+), sodium(Na+), calcium(Ca2+) ion concentrations within very compressed limits, to achieve the constancy of internal environment.

 

The volume of extracellular fluid is generally 15 L. This 15 L consists of both interstitial and plasma, which are respectively 12 and 3 L. therefore, 16 % of human body weight is made up by interstitial and 4 % is made up by plasma.

 

A large amount of sodium, chloride, bicarbonate ions plus nutrients for the cells like-glucose, oxygen, fatty acids, amino acids are naturally found in Extracellular fluid. There is also found carbon dioxide in Extracellular that is being transported from the cells to the lungs to be evacuated as well as other cellular waste products that are being transported to the kidneys for the evacuation.

 

Extracellular Fluid and Weight Loss

 

Since no specific relation of Extracellular fluid has caught my attention with weight loss or gain, yet, more steps should be taken to find out anything hidden about it. As far as the weight loss always matters many, so a strong connection of Extracellular fluid with weight loss process which either could be positive or negative may mitigate many of our worriedness, especially who are very health nut.

 

In short, I would like to end with the sentence that, Extracellular fluid is the fluid naturally found outside of the cell, aiding the function of a particular tissue which comprises plasma, tissue fluid, and Transcellular fluid.in extracellular fluid, the concentration of sodium ions is high and the concentration of potassium ions is low. It comprises of nearly 45 percent of body water and 27 percent of total body weight.
