What is the composition of each of the body fluid compartments?

The extracellular fluid is mainly cations and anions. The cations include: sodium (Na+ = 136-145 mEq/L), potassium (K+ = 3.5-5.5 mEq/L) and calcium (Ca2+ = 8.4-10.5 mEq/L). Anions include: chloride ( mEq/L) and hydrogen carbonate (HCO3- 22-26 mM). These ions are important for water transport throughout the body.

What are the compositions of body fluid?

Solute Composition of Body Water

Electrolyte, mEq/L Extracellular Fluid Intracellular Fluid
Sodium 140 13
Potassium 4 140
Calcium 5

What percentage of body fluids is blood?

Where is water in the body

Body part Water percentage
Muscles 70–75%
Liver 70–75%
Skin 70–75%
Blood 50%

Where is fluid found in the body?

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.

How does body fluid move between compartments?

In the body, water moves through semi-permeable membranes of cells and from one compartment of the body to another by a process called osmosis. Osmosis is basically the diffusion of water from regions of higher concentration to regions of lower concentration, along an osmotic gradient across a semi-permeable membrane.

What are the major fluid compartments of the body?

The body’s fluid separates into two main compartments: Intracellular fluid volume (ICFV) and extracellular fluid volume (ECFV).

What are the 4 fluid compartments of the body?

The following body fluid compartments are described: total body water (TBW), extracellular fluid (ECF), intracellular fluid (ICF), transcellular fluid TCF), plasma volume, red cell volume and interstitial fluid volume.

What is fluid compartment in human body?

fluid compartment: fluid inside all cells of the body constitutes a compartment system that is largely segregated from other systems. hydrostatic pressure: pressure exerted by a fluid against a wall, caused by its own weight or pumping force. interstitial fluid (IF): fluid in the small spaces between cells not contained within blood vessels

What is the composition of body fluids?

Composition of Body Fluids. Blood plasma has high concentrations of sodium, chloride, bicarbonate, and protein. The IF has high concentrations of sodium, chloride, and bicarbonate, but a relatively lower concentration of protein. In contrast, the ICF has elevated amounts of potassium, phosphate, magnesium, and protein.

What are the three types of fluid found in the extracellular compartment?

The fluid contained in the extracellular compartment is divided into three: interstitial fluid, blood plasma, and fluids contained in special compartments of the body. Interstitial fluid surrounds cells, bathing and “supporting” them.

What type of fluid surrounds all cells in the body?

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 (Figure 26.1.2).
