What are the two main compartments of the ECF?
The body’s fluid separates into two main compartments: Intracellular fluid volume (ICFV) and extracellular fluid volume (ECFV).
What are three types ECF compartments?
The extracellular fluids may be divided into three types: interstitial fluid in the “interstitial compartment” (surrounding tissue cells and bathing them in a solution of nutrients and other chemicals), blood plasma and lymph in the “intravascular compartment” (inside the blood vessels and lymphatic vessels), and small …
What is in 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).
Which is the same in the ICF and in the blood plasma?
The compositions of the two components of the ECF—plasma and IF—are more similar to each other than either is to the ICF. Blood plasma has high concentrations of sodium, chloride, bicarbonate, and protein. In contrast, the ICF has elevated amounts of potassium, phosphate, magnesium, and protein.
What happens when ECF volume decreases?
ECF volume is related to effective circulating volume. A decrease in ECF (hypovolemia) generally causes a decrease in effective circulating volume, which in turn causes decreased organ perfusion and leads to clinical sequelae.
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.
How is ICF calculated?
A simple tool is the 60-40-20 rule. Approximately 60% of body weight is water (TBW), 40% of body weight is ICF, and 20% is ECF. (ICF is 2/3 of TBW, i.e., 40% of body weight; ECF is 1/3 of TBW, i.e., 20% of body weight.)
What are the components of ECF?
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, gut fluid, etc.). The interstitial fluid and the blood plasma are the major components of the extracellular fluid.
What is ECF made of?
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.
Is plasma ICF or ECF?
How are the compartments of the ECF different?
A similar argument applies to the Extracellular Fluid. The ECF is divided into several smaller compartments (eg plasma, Interstitial fluid, fluid of bone and dense connective tissue and transcellular fluid). These compartments are distinguished by different locations and different kinetic characteristics.
Which is part of the intracellular fluid ( ICF )?
Figure 26.1.2 – Fluid Compartments in the Human Body: 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. Materials travel between cells and the plasma in capillaries through the IF.
What causes body water to move from ICF to ECF?
(1) Excessive NaCl intake causes moving water from ICF to ECF. (2) Excessive sweating may cause a decrease in total body water, and an increase in ECF osmolality. (3) Excessive water intake increases total body water and decreases ECF osmolality.
What’s the difference between the ICF and the if?
The IF has high concentrations of sodium, chloride, and bicarbonate, but a relatively lower concentration of protein. In contrast, the ICF has elevated amounts of potassium, phosphate, magnesium, and protein.
