Which are the predominant ions carried in plasma?
Multiple select question.
Ca2+Na+HCO3-KCl-
Solution
To determine the predominant ions carried in plasma, let’s analyze the options given:
- Ca²⁺ (Calcium ion): Present in plasma, but not one of the most abundant ions.
- Na⁺ (Sodium ion): The most abundant cation in extracellular fluid and plays a key role in fluid balance and nerve transmission.
- HCO₃⁻ (Bicarbonate ion): Important for maintaining the pH balance in blood, significant in plasma.
- K⁺ (Potassium ion): Present but in lower concentration compared to sodium.
- Cl⁻ (Chloride ion): Commonly found in plasma, helps balance the charges of other ions.
Final Answer:
The predominant ions carried in plasma are:
- Na⁺ (Sodium ion)
- HCO₃⁻ (Bicarbonate ion)
- Cl⁻ (Chloride ion)
Ca²⁺ and K⁺ are present but are not considered predominant.
