What are the compartments of ECF?
The interstitial, intravascular and transcellular compartments comprise the extracellular compartment. Its extracellular fluid (ECF) contains about one-third of total body water.
What are the three compartments of the extracellular fluid area?
There are three major fluid compartments; intravascular, interstitial, and intracellular.
What is ECF composed of?
The ECF consists of all the fluids located outside the cells and includes the plasma (0.05 l/kg), interstitial fluid and lymph (0.15 l/kg), and the transcellular fluids (Edelman and Leibman, 1959; Rose, 1984; Saxton and Seldin, 1986).
Is plasma ICF or ECF?
The two main fluid compartments are divided by the cell membrane into the extracellular fluid (ECF) and the intracellular fluid (ICF). The ICF is further divided by the capillary endothelium into the intravascular space (plasma) and the interstitial space.
What is the distribution of water in the ICF and ECF?
of the total body water is intracellular and the remainder extracellular. This equates to 40% of the total body weight as ICF and the remaining 20% as ECF . The ECF may be subdivided by the capillary endothelium into the intravascular space and the interstitial space.
Is plasma ECF or ICF?
Which two fluid compartments make up the extracellular fluid?
The extracellular fluid can be divided into two major subcompartments: interstitial fluid and blood plasma. The extracellular fluid also includes the transcellular fluid; this makes up only about 2.5% of the ECF.
How do the compositions of ECF and ICF differ?
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.
How are body fluids are distributed in compartments?
Fluid is separated into compartments by semipermeable membranes. The membranes are highly permeable to water but require energy to transport ions. Distribution of fluid between intracellular and extracellular compartments is determined by the concentration of Na+, chloride. Electrolytes , and other electrolytes.
Is mitochondria ECF or ICF?
Intracellular Fluid (ICF) Organelles like the nucleus, endoplasmic reticulum, mitochondria, lysosomes, and Golgi apparatus are suspended in and supported by the ICF.
What is the difference between edema and third spacing?
Edema may form which is an abnormal accumulation of fluid in the interstitium; and “third spacing” which refers to an abnormal accumulation of fluid within body tissue or a body cavity may occur. Five types of edema have been identified as a result of impaired balance between fluid compartments.
What are the 2 fluid compartments differentiate them?
The body’s fluid separates into two main compartments: Intracellular fluid volume (ICFV) and extracellular fluid volume (ECFV). Of the 42L of water found in the body, two-thirds of it is within the intracellular fluid (ICF) space, which equates to 28L.
What is third spacing called now?
Third spacing occurs when intravenous fluid shifts out of circulation in the blood and into the space between cells in organs and tissues, also known as interstitial space.
