Kidneys are the main organs, witch manage electrolytes balance, water balance, acid base balance, help regulation of blood pressure through rennin angiotensin aldosterone mechanism and attach hydrogen atom to position one to make active form of it. It also secrete the hormone called "Erythropoitin", witch stimulates formation of red blood cells. You have about 0.150 mole of sodium chloride in extra cellular fluid with calcium in much lower concentration and potassium chloride in intro cellular fluid in about 0.150 mole concentration with magnesium in very low concentration.

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.


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.


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.


What is found in extracellular fluid?

The principal elements in the extracellular fluid are sodium, potassium and calcium.


What is the major cation in extracellular fluid?

The Chief Extracellular cation is sodium.


Do neuroglia regulate extracellular fluid composition?

Yes, neuroglia help regulate extracellular fluid composition by assisting in the maintenance of ion concentrations, pH balance, and nutrient delivery in the brain and spinal cord. Astrocytes, a type of neuroglia, play a crucial role in this physiological regulation by creating a barrier between the blood vessels and the neurons.


What is the primary extracellular fluid cation in the body?

The primary extracellular fluid cation in the body is sodium (Na+). It plays a crucial role in maintaining fluid balance, nerve function, and muscle contraction.


What is the most cation extracellular fluid?

calcium ; sodium


What is the principal cation in extracellular fluid?

Sodium is the primary cation for ECF, potassium is the primary cation for ICF.


Where is sodium stored in the cell?

Sodium is primarily stored outside the cell in the extracellular fluid. It is found in high concentrations in the fluid surrounding the cell and plays an essential role in maintaining cell function and regulating cellular processes such as osmosis and membrane potential.


What is the Most abundant positive electrolyte in extracellular fluid?

Sodium ion is the most concentrated ion in the extracellular fluid.


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.
