The full name of the sodium-potassium pump is sodium-potassium ATPase, which is essentially a special protein present in the cell membrane, and its main role is to maintain the difference in ion concentration between inside and outside the cell, and to participate in the formation of the resting potential. The sodium-potassium pump can pump three sodiums out of the cell and two potassiums into the cell by breaking down the ATP, thus creating an intracellular negatively charged extracellularly positively charged situation, and thus also participating in the formation of the resting potential. It also allows sodium to be pumped out of the cell so that the cell does not become edematous due to excess intracellular sodium. This intracellular and extracellular concentration difference formed by the sodium-potassium pump can not only maintain the homeostasis of the body, but also prevent some pathological changes caused by cellular edema, which shows that the role of the sodium-potassium pump in the human body is crucial.
