What is another name for interstitial fluid?
Alternate Synonyms for “interstitial fluid”: extracellular fluid; ECF.
What is intracellular fluid called?
The fluid inside the cell is called intracellular fluid (ICF). All the fluid outside of the cell is called extracellular fluid (ECF) and is separated from the intracellular fluid by a semipermeable membrane that surrounds the cell.
What does the interstitial fluid contain?
Interstitial fluid contains glucose, salt, fatty acids and minerals such as calcium, magnesium and potassium. The nutrients in interstitial fluid come from blood capillaries Interstitial fluid can also hold waste products which result from metabolism.
Is interstitial fluid the same as intercellular fluid?
The intracellular fluid (ICF) is the fluid within cells. The interstitial fluid (IF) is part of the extracellular fluid (ECF) between the cells. The intracellular fluid (ICF) compartment is the system that includes all fluid enclosed in cells by their plasma membranes.
Where is the interstitial fluid found?
Fluid found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them.
Is blood interstitial fluid?
Interstitial fluid is the body fluid between blood vessels and cells, containing nutrients from capillaries by diffusion and holding waste products discharged out by cells due to metabolism. Eleven litres of the ECF is interstitial fluid and the remaining three litres is plasma.
How do you remove interstitial fluid?
Key Points
- The lymphatic system is a linear network of lymphatic vessels and secondary lymphoid organs.
- It is responsible for the removal of interstitial fluid from tissues into lymph fluid, which is filtered and brought back into the bloodstream through the subclavian veins near the heart.
What is the relationship between blood and interstitial fluid?
blood is a liquid connective tissue that consists of cells surrounded by a liquid extracellular matrix. Interstitial fluid is the fluid that bathes body cells and is constantly renewed by the blood.
What happens when interstitial fluid accumulates?
Excessive accumulation of interstitial fluid is generally viewed as detrimental to tissue function because edema formation increases the diffusion distance for oxygen and other nutrients, which may compromise cellular metabolism in the swollen tissue.
What will cause an interstitial edema?
It may be caused by increased permeability of brain capillary endothelial cells, focal strokes, swelling of brain cells associated with hypoxia or water intoxication, trauma to the skull, or interstitial edema due to obstructive hydrocephalus.
What increases interstitial fluid?
Interstitial edema and an increased interstitial fluid volume commonly form in response to increased microvascular pressure, increased microvascular permeability, and inflammatory-related changes in mechanical relationships within the interstitial space.
How is interstitial fluid calculated?
To calculate the interstitial (fluid not in the cells and not in the blood) fluid volume, subtract the plasma volume from the extracellular volume. To calculate the intracellular fluid volume subtract the extracellular fluid volume from the total fluid volume.
What is the difference between interstitial fluid and plasma?
The key difference between plasma and interstitial fluid is that the plasma is the fluid in which the blood cells and platelets suspend while the interstitial fluid is the fluid that surrounds the cells in an organism. Water is the main component of body fluids.
How does interstitial fluid become lymph?
It is derived from blood plasma as fluids pass through capillary walls at the arterial end. As the interstitial fluid begins to accumulate, it is picked up and removed by tiny lymphatic vessels and returned to the blood. As soon as the interstitial fluid enters the lymph capillaries, it is called lymph.
What percentage of body fluids does interstitial fluid account for?
The extracellular fluid comprises approximately 20% of total body weight and further subcategorizes as plasma at approximately 5% of body weight and interstitial space which is approximately 12% of body weight.

What are the three types of body fluids?
Biological fluids include blood, urine, semen (seminal fluid), vaginal secretions, cerebrospinal fluid (CSF), synovial fluid, pleural fluid (pleural lavage), pericardial fluid, peritoneal fluid, amniotic fluid, saliva, nasal fluid, otic fluid, gastric fluid, breast milk, as well as cell culture supernatants.
What diseases are carried in body fluids?
Examples of diseases spread through blood or other body fluids:
- hepatitis B – blood, saliva, semen and vaginal fluids.
- hepatitis C – blood.
- human immunodeficiency virus (HIV) infection – blood, semen and vaginal fluids, breastmilk.
- cytomegalovirus (CMV) infection – saliva, semen and vaginal fluids, urine, etc.
Is pus a body fluid?
A white, yellow or brown viscous fluid that accumulates at sites of infection, pus usually consists of bacteria, white blood cells, and other proteins and cell debris. Pus under the skin is often found in a pimple, but deeper in the body a larger collection is known as an abscess.
