Quick Answer: What Is The Difference Between Extracellular Fluid And Interstitial Fluid?

What are the 4 major body fluids?

Common Bodily Fluids – What Makes the List?Blood.

Blood plays a major role in the body’s defense against infection by carrying waste away from our cells and flushing them out of the body in urine, feces, and sweat.



Vaginal fluids.



What are the major intracellular and extracellular electrolytes?

These substances are located in the extracellular and intracellular fluid. Within the extracellular fluid, the major cation is sodium and the major anion is chloride. The major cation in the intracellular fluid is potassium. These electrolytes play an important role in maintaining homeostasis.

What is the difference between interstitial fluid and plasma?

The main difference between plasma and interstitial fluid is that plasma contains more proteins whereas interstitial fluid contains fewer proteins. Most of the other dissolved products such as nutrients and electrolytes occur in similar concentrations in both plasma and interstitial fluid.

What makes up extracellular fluid?

The extracellular fluid is mainly cations and anions. Plasma is mostly water and dissolved proteins, but also contains metabolic blood gasses, hormones, and glucose. The composition of transcellular fluid varies, but some of its main electrolytes include sodium ions, chloride ions, and bicarbonate ions.

What is an example of interstitial fluid?

It makes up about 26% of the total body water composition in humans. It 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 is the fluid that fills the spaces between cells.

Is blood interstitial fluid?

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.

What do you mean by interstitial fluid?

Fluid found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). … As new interstitial fluid is made, it replaces older fluid, which drains towards lymph vessels. When it enters the lymph vessels, it is called lymph. Also called tissue fluid.

Does interstitial fluid contain white blood cells?

The plasma that filters through the blood capillaries into the interstitial fluid does not contain red blood cells or platelets as they are too large to pass through but can contain some white blood cells to help the immune system.

How is interstitial fluid removed?

It is the site of many immune system functions as well as its own functions. 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 are the three types of extracellular fluid?

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 percent of extracellular fluids in the human body is interstitial?

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 is the most common cation found in the interstitial fluid?

The most abundant cation in intracellular fluid is potassium.

Where is extracellular fluid found?

Extracellular fluid, in biology, body fluid that is not contained in cells. It is found in blood, in lymph, in body cavities lined with serous (moisture-exuding) membrane, in the cavities and channels of the brain and spinal cord, and in muscular and other body tissues.
