What is the difference between intracellular fluid and extracellular fluid?
The intracellular fluid is the fluid contained within cells. 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.
What is the composition of ICF and ECF?
The ICF has higher amounts of potassium, phosphate, magnesium, and protein compared to the ECF. The plasma has high concentrations of sodium, chloride, and bicarbonate, but lower levels of protein as compared to the ICF.
Which is more ICF or ECF?
The body contains 2 major fluid compartments: the intracellular fluid (ICF) and the extracellular fluid (ECF). The ICF comprises of two thirds of the total body water (TBW), while the ECF accounts for the remaining third. The ECF is further divided into the interstitial fluid (75%) and plasma (25%).
What is the extracellular fluid?
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 intracellular fluid called?
cytosol
Intracellular fluid is often referred to as cytosol when discussing cellular functions. The cytosol and the organelles and molecules contained within are referred to collectively as the cytoplasm.
Why is the intracellular fluid ICF different in composition to the extracellular fluid ECF )?
The composition of intracellular and extracellular fluid differs by the presence of high concentration of sodium ions and low concentration of potassium ions in the extracellular fluid.
Is blood ICF or ECF?
The intracellular fluid (ICF) is the fluid within cells. The interstitial fluid (IF) is part of the extracellular fluid (ECF) between the cells. Blood plasma is the second part of the ECF.
What is the percentage of intracellular fluid?
Intracellular fluid is approximately 40% of the total body weight. It is the total space within cells primarily defined as the cytoplasm of cells.
How many liters are intracellular fluid?
Approximately 67% of total body water (or ~40% of total body weight) is in the intracellular fluid (ICF) compartment, which is the fluid that is present in the cytoplasm of all cells of the body. Therefore, the total volume of ICF is ~28 L (cytoplasmic volume of all cells combined).
Is there more ICF or ECF?
The body contains 2 major fluid compartments: the intracellular fluid (ICF) and the extracellular fluid (ECF). The ICF comprises of two thirds of the total body water (TBW), while the ECF accounts for the remaining third.
What are the 3 fluid spaces?
There are three major fluid compartments; intravascular, interstitial, and intracellular. Fluid movement from the intravascular to interstitial and intracellular compartments occurs in the capillaries.
What is the difference between intracellular and extracellular fluid (ECF)?
The intracellular fluid (ICF) and extracellular fluid (ECF) are separated by a semi-permeable cell membrane that is permeable to water but not to most solutes including electrolytes and proteins, which generally need transport systems to move across the m embrane. Title Intracellular fluid (ICF) and Extracellular fluid (ECF) Author CDC Subject
What is intracellular fluid (ICF)?
Intracellular Fluid (ICF) The fluid inside of cells, also called the cytoplasm or cytosol, makes up about 60% of the water in the human body, totaling about 7 gallons.
What is found in ICF and ECF?
Also found in the ICF are cellular building blocks like sugars, proteins, carbohydrates, and lipids. ECFs are any body fluids that are not inside cells. The two main components of ECF are plasma and interstitial fluid (IF).
What is the osmolality of ICF and ECF?
Despite the different compositions of ICF and ECF, the total solute concentration (osmolality) of these two fluid compartments is normally the same. ICF and ECF are in osmotic equilibrium because of the high water permeability of cell membranes, which does not permit an osmolality difference to be sustained.
