Verified step by step guidance1
Understand the concept of electrolytes: Electrolytes are minerals in your body that have an electric charge. They are essential for various bodily functions, including maintaining fluid balance, transmitting nerve signals, and muscle contractions.
Identify the location: The problem specifies the extracellular fluid, which is the fluid outside of cells. This includes blood plasma and interstitial fluid.
Recognize the role of sodium: Sodium is the most abundant electrolyte in the extracellular fluid. It plays a crucial role in maintaining osmotic balance and fluid distribution between compartments.
Consider the other options: Calcium, magnesium, phosphate, potassium, and chloride are also electrolytes, but they have different roles and concentrations in the body. For example, potassium is more prevalent in intracellular fluid.
Conclude with the correct answer: Based on the understanding of electrolyte distribution, sodium is the most prevalent electrolyte in the extracellular fluid.
