Verified step by step guidance

Understand the role of potassium in the human body: Potassium is an essential mineral and electrolyte that plays a crucial role in various physiological processes.

Identify the primary functions of potassium: Potassium is involved in maintaining fluid balance, transmitting nerve signals, and regulating muscle contractions, including those of the heart.

Focus on the cardiovascular system: Potassium helps regulate blood pressure by balancing the effects of sodium and maintaining proper function of the heart and blood vessels.

Eliminate incorrect options: Transporting oxygen in the blood is primarily the function of hemoglobin in red blood cells, forming the structure of bones is mainly the role of calcium and phosphorus, and synthesizing DNA involves nucleotides and enzymes, not potassium.

Conclude with the correct function: Based on the understanding of potassium's role, the primary function related to the options given is regulating blood pressure.
