potassium ions

Hyperkalemia (High Potassium)

Background Potassium ions play an important role in many biological processes, particularly in the generation of membrane and action potentials and electrical conduction in nerve cells and the heart. Potassium is 98% localized intracellularly. The primary active transporter Na+/K+-ATPase provides transport into cells. Two hormones maintain the deep extracellular potassium concentration. The first is insulin, … Hyperkalemia (High Potassium)
