What separates the intracellular and extracellular fluid compartments?
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.
Helps regulate the ionic composition of CNS extracellular fluid?
The blood-brain barrier helps regulate the ion concentration in the extracellular fluid of the central nervous system by restricting the passage of certain ions and molecules between the blood and the brain. This selective barrier maintains the delicate balance of ions necessary for proper neuronal function and protects the brain from potentially harmful substances present in the bloodstream.
Is the extracellular fluid hydrophilic or hydrophobic?
The extracellular fluid is hydrophilic, meaning it is attracted to water.
Extracellular fluid would not include?
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.
Extracellular fluid is found everywhere in the body EXCEPT?
Extracellular is outside cells and intracellular is inside, so that extracellular fluid would not be inside cells.
How does the cytosol differ in composition from the extracellular fluid?
The cytosol contains a higher concentration of proteins and lower levels of sodium ions compared to extracellular fluid. Additionally, the cytosol houses various organelles and structures that are not present in the extracellular fluid.

What mineral helps regulate extracellular volume?
Sodium is the mineral that helps regulate extracellular volume. It plays a crucial role in maintaining fluid balance in the body by controlling the amount of water that is retained or excreted. Sodium levels are tightly controlled by the kidneys to help regulate extracellular volume and maintain overall body hydration.
Which body fluid has same composition as ringers lactate?
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.
The main hormone that acts on the kidneys to regulate sodium ion concentration of the extracellular fluid is?
Aldosterone is the main hormone that acts on the kidneys to regulate sodium ion concentration of the extracellular fluid. Aldosterone promotes the reabsorption of sodium ions and water in the kidneys, which helps to maintain blood pressure and electrolyte balance in the body.
Are the principal ions in extracellular fluid sodium and chloride and bicarbonate?
Yes, the principal ions in extracellular fluid are sodium, chloride, and bicarbonate. Sodium and chloride are the major cations and anions, respectively, while bicarbonate helps regulate pH balance in the body.
What is found in extracellular fluid?
The principal elements in the extracellular fluid are sodium, potassium and calcium.
Is the extracellular fluid hydrophilic or hydrophobic?
The extracellular fluid is hydrophilic, meaning it is attracted to water.
Where is the extracellular fluid found in the body?
Extracellular is outside cells and intracellular is inside, so that extracellular fluid would not be inside cells.
What is the main buffer in the extracellular fluid?
The main buffer in the extracellular fluid is the bicarbonate buffer system, which consists of bicarbonate ions and carbonic acid. This system helps to regulate the pH of the blood by maintaining a balance between H+ ions and bicarbonate ions.
Extracellular fluid would not include?
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.
