Extracellular fluid, in biology, body fluid that is not contained in cells. It is found in blood, in lymph, in body cavities lined with serous (moisture-exuding) membrane, in the cavities and channels of the brain and spinal cord, and in muscular and other body tissues.
Is blood intracellular or extracellular fluid?
The blood represents both the intracellular compartment (the fluid inside the blood cells) and the extracellular compartment (the blood plasma).
What are examples of extracellular fluid?
Examples of this fluid are cerebrospinal fluid , aqueous humor in the eye, serous fluid in the serous membranes lining body cavities, perilymph and endolymph in the inner ear, and joint fluid. Due to the varying locations of transcellular fluid, the composition changes dramatically.
Why is blood an extracellular fluid?
Extracellular fluid that travels in the circulatory system is blood plasma, the liquid component of blood. As the oxygen and nutrients from blood are transferred out of the blood in the capillaries , these molecules make their way to another extracellular fluid that surrounds individual cells within the body.
Is blood interstitial fluid?
The ECF components are: interstitial fluid ( fluid between the cells ), lymph (fluid that circulates throughout the lymphatic system), and blood.
Where is extracellular fluid found?
Extracellular fluid, in biology, body fluid that is not contained in cells. It is found in blood , in lymph, in body cavities lined with serous (moisture-exuding) membrane, in the cavities and channels of the brain and spinal cord, and in muscular and other body tissues.
What is the other name of extracellular fluid?
Answer: The other name of extracellular fluid is ‘ filler substance’ . Extracellular fluid represents all the body fluid which is present outside the cells.
What is only found in intracellular fluid?
Potassium is found mostly in the intracellular fluid, and is used to estimate body cell mass. Body cell mass is the fat-free intracellular space and the most metabolically active part of the body.
What are the six components of extracellular fluid?
The extracellular fluid, in turn, is composed of blood plasma, interstitial fluid, lymph and transcellular fluid (e.g. cerebrospinal fluid, synovial fluid, aqueous humour, serous fluid
What is ECF full form?
Abbreviation for extracellular fluid .
What is an example of interstitial fluid?
interstitial fluid: A solution that bathes and surrounds the cells of multicellular animals ; also called tissue fluid. plasma: The straw-colored/pale-yellow, liquid component of blood that normally holds the blood cells of whole blood in suspension.
What is the relationship between blood and interstitial fluid?
blood is a liquid connective tissue that consists of cells surrounded by a liquid extracellular matrix. Interstitial fluid is the fluid that bathes body cells and is constantly renewed by the blood .
Is interstitial fluid and extracellular fluid the same?
The extracellular fluid—the fluid outside the cells—is divided into that found within the blood and that found outside the blood; the latter fluid is known as the interstitial fluid.
How much extracellular fluid is in the human body?
The extracellular fluid comprises approximately 20% of total body weight and further subcategorizes as plasma at approximately 5% of body weight and interstitial space which is approximately 12% of body weight.
What are the 4 major body fluids?

What are the 3 major body fluid compartments?
There are three major fluid compartments; intravascular, interstitial, and intracellular . Fluid movement from the intravascular to interstitial and intracellular compartments occurs in the capillaries.
