What is the role of potassium in the body?

• A. Maintaining acid-base balance
• B. Regulating heart rhythm
• C. Both a and b
• D. None of the above

Answer: (C)

Potassium plays a vital role in several physiological processes within the body, and its significance in both maintaining acid-base balance and regulating heart rhythm underscores its importance. Firstly, potassium is crucial for maintaining acid-base balance, which refers to the regulation of acidity and alkalinity in the body fluids. It helps in the neutralization of acids and bases, promoting a stable internal environment essential for cellular function. Secondly, potassium is integral in regulating heart rhythm. It is a key electrolyte that facilitates proper electrical activity in the heart, influencing the pacing of heartbeats. An appropriate level of potassium is necessary to prevent arrhythmias, which can be life-threatening. Therefore, recognizing potassium's dual roles in both maintaining acid-base balance and regulating heart rhythm demonstrates its essential contribution to maintaining overall health and function in the body.
