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.

Recognize that potassium is not involved in forming the structure of bones. Calcium and phosphorus are the primary minerals responsible for bone structure.

Acknowledge that potassium does not directly transport oxygen in the blood. Hemoglobin, a protein in red blood cells, is responsible for oxygen transport.

Note that potassium is not directly involved in synthesizing DNA. DNA synthesis primarily involves nucleotides and enzymes like DNA polymerase.

Identify that one of the key functions of potassium is to help regulate blood pressure. Potassium helps balance sodium levels in the body, which is crucial for maintaining healthy blood pressure.
