There are three major fluid compartments; intravascular, interstitial, and intracellular.
What are body fluid compartments?
There are two main fluid compartments water occupies in the body. About two-thirds is in the intracellular fluid compartment (ICF). The intracellular fluid is the fluid within the cells of the body. The remaining one-third of body water is outside cells, in the extracellular fluid compartment (ECF).
What is the difference between intracellular and extracellular fluid?
Intracellular fluid is the liquid located inside the cells, while extracellular fluid surrounds the cells. While intracellular fluid contains proteins and amino acids and has a concentration gradient, extracellular fluid presents with more ions. Cells typically maintain a different components inside their system.
Where would you find the intracellular fluid?
Intracellular fluid is the place where most of the fluid in the body is contained. This fluid is located within the cell membrane and contains water, electrolytes and proteins. Potassium, magnesium, and phosphate are the three most common electrolytes in the ICF.
What is the interstitial fluid?
The main component of the extracellular fluid is the interstitial fluid which surrounds the cells in the body. The other major component of the ECF is the intravascular fluid of the circulatory system called blood plasma. The remaining small percentage of ECF includes the transcellular fluid.
What is the fluid in the body?
Body fluids are liquids originating from inside the bodies of living humans. They include fluids that are excreted or secreted from the body. Human blood, body fluids, and other body tissues are widely recognised as vehicles for the transmission of human disease.
What are body compartments?
Fluid compartments. The two main fluid compartments are the intracellular and extracellular compartments. The intracellular compartment is the space within the organism's cells; it is separated from the extracellular compartment by cell membranes.
What factors govern the movement of fluids between body compartments?
Hydrostatic pressure is the force exerted by a fluid against a wall and causes movement of fluid between compartments. Fluid can also move between compartments along an osmotic gradient. Active transport processes require ATP to move some solutes against their concentration gradients between compartments.
What is the source of water in the body?
Food Sources. You get some of the water in your body through the foods you eat. Some of the water is made during the process of metabolism. You also get water through liquid foods and beverages, such as soup, milk, tea, coffee, soda, drinking water, and juices.
What is the most abundant anion in the intracellular fluid?
The most abundant cation (or positively charged ion) in the extracellular fluid (ECF) is sodium (Na+). The most abundant anion (or negatively charged ion) in the ECF is chloride (Cl-). The most abundant cation in the intracellular fluid (ICF) is potassium (K+).
Who is most at risk of becoming dehydrated?
Anyone can become dehydrated, but certain people are at greater risk:
- Infants and children. The most likely group to experience severe diarrhea and vomiting, infants and children are especially vulnerable to dehydration.
- Older adults.
- People with chronic illnesses.
- People who work or exercise outside.
What is meant by the term fluid balance?
Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges.
Is cytoplasm intracellular fluid?
The cytosol, also known as intracellular fluid (ICF) or cytoplasmic matrix, is the liquid found inside cells. It is separated into compartments by membranes. For example, the mitochondrial matrix separates the mitochondrion into many compartments.
What is the intravascular volume?
In medicine, intravascular volume status refers to the volume of blood in a patient's circulatory system, and is essentially the blood plasma component of the overall volume status of the body, which otherwise includes both intracellular fluid and extracellular fluid.
What is in the intravascular fluid?
intravascular fluid. a term sometimes used to refer to that part of the extracellular fluid that is within the blood vessels, i.e., the plasma.
What is third space syndrome?
Third-spacing occurs when too much fluid moves from the intravascular space (blood vessels) into the interstitial or "third" space-the nonfunctional area between cells. This can cause potentially serious problems such as edema, reduced cardiac output, and hypotension.
What is the meaning of Transcellular fluid?
Transcellular fluid is the portion of total body water contained within epithelial lined spaces. It is the smallest component of extracellular fluid, which also includes interstitial fluid, lymph and plasma.
How do the kidneys maintain water balance in the body?
The kidneys maintain our body's water balance by controlling the water concentration of blood plasma. The kidneys also control salt levels and the excretion of urea. Water that is not put back into the blood is excreted in our urine.
Is blood ECF or ICF?
The fluid compartment called the blood volume is interesting in that it is a composite compartment containing ECF (plasma) and ICF (red cell water). The fluid of bone & dense connective tissue is significant because it contains about 15% of the total body water.
Where do you find 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.
