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.
How much extracellular fluid is interstitial fluid?
The interstitial fluid is essentially comparable to plasma. The interstitial fluid and plasma make up about 97% of the ECF, and a small percentage of this is lymph.
What is the difference between extracellular and intracellular regulation of liquids?
The main difference between intercellular and extracellular fluid is that intracellular fluid is the liquid found inside the cell whereas extracellular fluid refers to all the body fluids outside the cell .
What is interstitial fluid if )?
(IN-ter-STIH-shul FLOO-id) 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.
What is the major 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.
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 ...
Is blood an extracellular fluid?
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.
What is an example of interstitial fluid?
interstitial fluid: A solution that bathes and surrounds the cells of multicellular animals ; also called tissue fluid. plasma: The straw-colored/pale-yellow, liquid component of blood that normally holds the blood cells of whole blood in suspension.
Is blood interstitial fluid?
The ECF components are: interstitial fluid ( fluid between the cells ), lymph (fluid that circulates throughout the lymphatic system), and blood.
What are the 4 major body fluids?
- 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. ...
- Saliva. ...
- Semen. ...
- Vaginal fluids. ...
- Mucus. ...
- Urine.
How do you remove interstitial fluid?
- 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 causes interstitial fluid?
Interstitial fluid is thought to be produced as a result of rhythmic alterations in arteriolar blood flow (vasomotion) , which brings about movement of fluids from the blood through the unfenestrated capillaries into the interstitial space.
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.
Does plasma have more protein than interstitial fluid?
The major driving force for inward flow of fluid (from the interstitial space to the intravascular space) is the colloid oncotic pressure difference. This difference is the result of a higher concentration of proteins in plasma than in the interstitial fluid.
What is the most common cation found in the interstitial 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 are the 3 major body 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.
