What happens across the membrane of an electrically active cell is a dynamic process that is hard to visualize with static images or through text descriptions. View this animation (http://openstaxcollege.org/l/dynamic1) to learn more about this process. What is the difference between the driving force for Na+ and K+? And what is similar about the movement of these two ions?

Homeostasis is any self-regulatory mechanism by which biological processes appear to remain stable and to adapt to survival conditions. In fact, the stability achieved is a complex balance in which constant transition takes place, but relatively even conditions prevail.
The sodium/potassium pump transfers the sodium ions and potassium ions outside and inside of the cell respectively. It helps regulate the ion level on both sides of the membrane of the cell but the movement of ions requires ATP. The concentration gradient could also be used to drive the ions in and out of the cells.
