Interstitial fluid, plasma, and transcellular fluid.
Cell membranes separate the intracellular and extracellular fluid compartments. The intracellular fluid is contained within the cells, while the extracellular fluid surrounds the cells. Transport proteins in the cell membrane regulate the movement of substances between these compartments.
The plasma membrane of cells separates the interstitial fluid (between cells) from the blood plasma. In addition, the blood vessels' walls, composed of endothelial cells, create a physical barrier between the blood and the surrounding interstitial fluid.
Sodium (Na+) is the most significant solute in determining the distribution of water among fluid compartments through osmosis. It plays a critical role in regulating fluid balance in the body by influencing the movement of water between cells and the extracellular fluid compartments.
The extracellular fluid is hydrophilic, meaning it is attracted to water.
Cells and intracellular components are not part of the extracellular fluid, as it is found outside of cells within the body. Intracellular fluid would not be considered part of the extracellular fluid.
Cell membranes separate the intracellular and extracellular fluid compartments. The intracellular fluid is contained within the cells, while the extracellular fluid surrounds the cells. Transport proteins in the cell membrane regulate the movement of substances between these compartments.
Transcellular fluid includes the water and electrolytes within the body's specialized compartments, such as cerebrospinal fluid, synovial fluid, and intraocular fluid. It is separate from the more generalized extracellular and intracellular fluid compartments.
The two major fluid compartments in the body are the intracellular fluid, which is located inside cells, and the extracellular fluid, which includes the fluid found outside of cells in the interstitial spaces and blood plasma.

The plasma membrane of cells separates the interstitial fluid (between cells) from the blood plasma. In addition, the blood vessels' walls, composed of endothelial cells, create a physical barrier between the blood and the surrounding interstitial fluid.
Sodium (Na+) is the most significant solute in determining the distribution of water among fluid compartments through osmosis. It plays a critical role in regulating fluid balance in the body by influencing the movement of water between cells and the extracellular fluid compartments.
Extracellular and intracellular fluids play a critical role in maintaining homeostasis by regulating the balance of water, electrolytes, and other substances within the body. These fluid compartments help maintain cell structure and function, as well as ensure proper communication and signaling between cells. Imbalances in these fluid compartments can disrupt homeostasis and lead to health issues.
An organ, such as the stomach or lungs, can be considered a compartment within the body. These compartments are essential for specific functions and are separated by membranes to maintain their unique environments. They work together to help the body function properly.
Osmotic pressure is the main force that drives fluid movement from intracellular to extracellular spaces. It is influenced by the concentration of solutes inside and outside the cell. Additionally, hydrostatic pressure gradients across cell membranes can also contribute to fluid movement between intracellular and extracellular compartments.
Perilymph is a fluid present in the scala vestibuli and scala tympani which are the perilymph compartments of the inner ear. It has the same ionic concentration as the extracellular fluid present in the entire body
Blood plasma, extracellular fluid, and lymph are all components of the body's fluid compartments and are interconnected in the circulatory and lymphatic systems. Blood plasma is the liquid portion of blood, which circulates nutrients, gases, and waste. Extracellular fluid encompasses all fluid outside of cells, including interstitial fluid, which is derived from plasma and bathes cells. Lymph, formed from interstitial fluid, returns excess fluid and proteins to the bloodstream, thus maintaining fluid balance and facilitating immune responses.
Ringer's lactate solution has a composition similar to that of extracellular fluid, particularly interstitial fluid. It contains sodium, potassium, calcium, chloride, and lactate ions, which mimic the electrolyte balance found in the body’s extracellular compartments. This similarity makes Ringer's lactate suitable for fluid resuscitation and electrolyte replacement in clinical settings.
