Select all that applyWhich are the predominant ions carried in plasma?Multiple select question.Cl-Na+KHCO3-Ca2+

To identify the predominant ions carried in plasma, let’s analyze the options provided:

1. Cl⁻ (Chloride): Chloride is indeed one of the major anions present in plasma. It plays a critical role in maintaining osmotic pressure and acid-base balance.

2. Na⁺ (Sodium): Sodium is the primary cation in plasma and is essential for various bodily functions, including fluid balance and nerve transmission.

3. K⁺ (Potassium): While potassium is significant in plasma, it is not present in as high a concentration as sodium or chloride. It is crucial for cellular functions but primarily exists in intracellular fluid.

4. HCO₃⁻ (Bicarbonate): Bicarbonate ions are vital for maintaining the acid-base balance in the body and are also found in substantial amounts in plasma.

5. Ca²⁺ (Calcium): Calcium is important for various physiological functions, including blood clotting and signal transduction, and is also found in plasma, albeit in lower concentrations compared to sodium and chloride.

Final Answer

The predominant ions carried in plasma are:

• Na⁺ (Sodium)
• Cl⁻ (Chloride)
• HCO₃⁻ (Bicarbonate)
• Ca²⁺ (Calcium)

So, the options you should select are Cl⁻, Na⁺, HCO₃⁻, and Ca²⁺.
