Sodium
Yes, potassium is the most abundant cation in intracellular fluid, while sodium is the most abundant cation in extracellular fluid. Potassium plays a critical role in many cellular functions, including maintaining membrane potential and regulating fluid balance within cells.
sodium
The most abundant cation in the extracellular fluid (ECF) is sodium (Na+). It plays a crucial role in maintaining fluid balance, facilitating nerve signaling, and supporting muscle contraction.
Interstitial fluid also called extracellular fluid.
Yes, the interstitial fluid is an extracellular fluid that surrounds the cells.
Sodium ion is the most concentrated ion in the extracellular fluid.
What plasma membrane contains two kinds of lipids
Most of the body's fluid is found inside cells (intracellular fluid) and in the space surrounding cells (extracellular fluid). The extracellular fluid includes the fluid within blood vessels (intravascular) and the fluid in between cells (interstitial fluid).
No, chloride is the most abundant negative ion in extracellular fluid, not calcium. Calcium is an important cation in the body and plays a role in various physiological processes, but it is not the most abundant negative ion in extracellular fluid.
Macrophages
Sodium is the primary cation for ECF, potassium is the primary cation for ICF.
Extracellular fluid refers to all body fluid outside of cells. The most abundant anion in the extracellular fluid is chloride (Cl-).
