Most abundant mineral of body fluid is

Options

A. Sodium
B. Chloride
C. Potassium
D. Phosphate

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for the most abundant mineral in body fluids. Body fluids include both extracellular and intracellular fluids.

2. **Identify Body Fluid Composition**: Body fluids are essential for transporting important ions necessary for metabolic processes. In a healthy adult, body fluids make up about 60% of total body weight, which is approximately 47 liters.

3. **Differentiate Between Fluid Types**: Body fluids are categorized into two types:
- **Extracellular Fluid**: This fluid is found outside the cells.
- **Intracellular Fluid**: This fluid is found inside the cells.

4. **Analyze the Options**: The options provided are sodium, chloride, potassium, and phosphate. We need to determine which of these is the most abundant in body fluids.
- **Sodium**: Predominantly found in extracellular fluid and constitutes about 60% of body fluids.
- **Chloride**: Present in trace amounts, making it less abundant.
- **Potassium**: Mainly found in intracellular fluid and is present in lesser amounts compared to sodium.
- **Phosphate**: Primarily found in bones, not in significant amounts in body fluids.

5. **Conclusion**: Based on the analysis, sodium is the most abundant mineral in body fluids, specifically in the extracellular fluid.

6. **Final Answer**: The most abundant mineral of body fluid is **sodium**.
