Intracellular fluid (ICF) is located inside the cells of the various tissues of the body. Extracellular fluid (ECF) is located in the spaces between cells. ECF can be further subdivided into plasma, interstitial fluid, and lymph fluid.

What does ICF mean in cells?
Human cells are bathed in fluids both inside the cell and out. In fact, the water that is inside the cell makes up about 42% of the total body weight. The fluid inside the cell is called intracellular fluid (ICF).
What is ICF in blood?
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 is intracellular fluid in biology?
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.
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 difference between intracellular and extracellular?
Comparison between Intracellular and Extracellular Enzymes The significant difference between intracellular and extracellular is that one acts inside the cell, and the other acts outside the cell.
What contains ICF?
The ICF framework consists of two parts: Functioning and Disability and Contextual Factors. These parts are further broken down in the following manner: Functioning and Disability includes: Body Functions and Structures—describes actual anatomy and physiology/psychology of the human body.
What causes ICF?
Another disease — immunodeficiency, centromeric instability and facial anomalies (ICF) syndrome — is caused by mutations in DNMT3B, ZBTB24, CDCA7, HELLS and possibly other yet to be identified genes.
What is the fluid inside a cell called?
Inside the cell there is a large fluid-filled space called the cytoplasm, sometimes called the cytosol. In prokaryotes, this space is relatively free of compartments. In eukaryotes, the cytosol is the “soup” within which all of the cell’s organelles reside. It is also the home of the cytoskeleton.
What is the main function of intracellular fluid?
The main function of intracellular fluid is to help with the transport of gases, nutrients, and other molecules. Intracellular fluid is also important for intracellular communication and cell signaling. Extracellular fluid is found in blood plasma and in the interstitial space between cells.
What are examples of intracellular fluid?
- Hyponatremia.
- Inorganic Ions.
- Glucose.
- Protein.
- Cell Membrane.
- Extracellular Fluid.
- Interstitial Fluid.
- Sodium Ion.
How does fluid move between ECF and ICF?
When a hyposmotic fluid is lost from the ECF, the volume of the ECF decreases, and the osmolarity increases. When the osmolarity in the ECF rises compared to ICF, water moves by osmosis from the ICF into the ECF.
Where is intracellular fluid found in the body?
The intracellular fluid (ICF) is all fluids contained inside the cells, which consists of cytosol and fluid in the cell nucleus. The cytosol is the matrix in which cellular organelles are suspended. The cytosol and organelles together compose the cytoplasm. The cell membranes are the outer barrier.
Is blood intracellular or extracellular?
Blood contains both extracellular fluid (the fluid in plasma) and intracellular fluid (the fluid in the red blood cells). However, blood is considered to be a separate fluid compartment because it is contained in a chamber of its own, the circulatory system.
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 are the 3 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.
Why is lymph called extracellular fluid?
Lymph does not travel inside the cells but travels free of the cells. It lies outside the cells; hence it is called extracellular fluid.
Is water extracellular fluid?
The adult human body is made up of 60% water and is divided into extracellular and intracellular fluid compartments. Extracellular fluid is present outside the cells and makes up ⅓ of the total body water. Intracellular fluid is present inside the cells and makes up ⅔ of the total body water.
Is human digestion intracellular or extracellular?
Since digestion occurs outside the cell, it is said to be extracellular. It takes place either in the lumen of the digestive system, in a gastric cavity or other digestive organ, or completely outside the body.
How much of body fluid is intracellular?
Intracellular fluid is approximately 40% of the total body weight. It is the total space within cells primarily defined as the cytoplasm of cells.
Are bacteria intracellular or extracellular?
Bacteria have historically been divided into two distinct groups: extracellular bacteria, which exist as free-living organisms in their environmental niches, and intracellular bacteria, which infect and replicate inside host cells.
What is the major intracellular cation?
The major cation in the intracellular fluid is potassium. These electrolytes play an important role in maintaining homeostasis.
What is intracellular fluid made of?
Intracellular Fluid Composition The cytosol or intracellular fluid consists mostly of water, dissolved ions, small molecules, and large, water-soluble molecules (such as proteins). This mixture of small molecules is extraordinarily complex, as the variety of enzymes that are involved in cellular metabolism is immense.
What affects intracellular fluid volume?
Changes in the intracellular fluid volume result from alterations in the osmolarity of the ECF but do not respond to isosmotic changes in extracellular volume. [8] However, any flow of water in or out of the cell membrane will have proportional changes in the ECFV.
What is ICF diagnosis?
The ICF conceptualises a person’s level of functioning as a dynamic interaction between her or his health conditions, environmental factors, and personal factors. It is a biopsychosocial model of disability, based on an integration of the social and medical models of disability.
