What fluid compartments make up the ECF?
Extracellular fluid (ECF) or extracellular fluid volume (ECFV) usually denotes all body fluid outside of cells, and consists of plasma, interstitial, and transcellular fluid. An extracellular matrix is an extracellular fluid space containing cell-excreted molecules, and they vary in their type and function.
What is the ECF compartment?
extracellular fluid (ECF): fluid exterior to cells; includes the interstitial fluid, blood plasma, and fluids found in other reservoirs in the body. fluid compartment: fluid inside all cells of the body constitutes a compartment system that is largely segregated from other systems.
What are the four body fluid compartments?
The following body fluid compartments are described: total body water (TBW), extracellular fluid (ECF), intracellular fluid (ICF), transcellular fluid TCF), plasma volume, red cell volume and interstitial fluid volume.
What are the 2 fluid compartments differentiate them?
The two main fluid compartments are the intracellular and extracellular compartments. The intracellular compartment is the space within the organism’s cells; it is separated from the extracellular compartment by cell membranes.
What are the 2 fluid compartments of the body?
The body’s fluid separates into two main compartments: Intracellular fluid volume (ICFV) and extracellular fluid volume (ECFV).
Where is the ICF and ECF?
Intracellular fluid (ICF) is the cytosol within the cell. Extracellular fluid (ECF) surrounds the cells serves as a circulating reservoir. The ECF is divided into the interstitial fluid which bathes the outside of the cells and intravascular fluid (i.e., plasma, lymph, and cerebral spinal fluid).
What is ECF example?
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.
How are body fluid compartments measured?
To measure the volume of any fluid compartment within the body you must inject or infuse a marker substance that will equilibrate (diffuse freely to a uniform concentration) throughout this compartment. To be a perfect marker a substance must also not be metabolised.
What are the three fluid compartments of the body quizlet?
Plasma.
What is extracellular fluid (ECF)?
Extracellular fluid (ECF) surrounds all cells in the body. Extracellular fluid has two primary constituents: the fluid component of the blood (called plasma) and the interstitial fluid (IF) that surrounds all cells not in the blood ( Figure 26.1.2 ).
What causes fluid to move between the ECF and ICF?
Once again, movement of fluid between the ECF and ICF is triggered by changes in the ECF Osmolarity. As seen for the case of isotonic saline infusion, no change in ECF occurs and thus now fluid moves between the two compartments.
What are the different types of ECF?
The body has other water-based ECF. These include the cerebrospinal fluid that bathes the brain and spinal cord, lymph, the synovial fluid in joints, the pleural fluid in the pleural cavities, the pericardial fluid in the cardiac sac, the peritoneal fluid in the peritoneal cavity, and the aqueous humor of the eye.
Why does the ECF contract during diarrhoea?
As a result, there is no shift in body fluid between the ICF and the ECF and thus the total volume of the ECF contracts due to its loss within in the diarrheal fluid.
