Potassium Regulation: Introduction
In this lesson you’ll learn the following:
1) How potassium is distributed throughout the body.
2) The role of potassium in cell physiology.
3) How potassium moves between the intracellular and extracellular compartments.

Amazingly perfect
How can I absorb 4700 mg per day without becoming hyperkalemia?
intrasailor and extrasailor
شكراا 💚
In our country , potassium is called kalcium (dont worry calium and kalcium arent same here)
THANK YOU SOOO MUCH!!!
Serum hypokalemia causes hyperpolarization of resting membane potential due to the altered K+ gradient. Serum hyperkalemia causes just the opposite. In case of hyperkalemia, a very much lesser than normal stimulus is required for depolarization of the membrane in order to initiate an action potential. All cells in a hyperkalemic environment are very excitable!..
Merci beaucoup
Making the membrane potential less negative (eg. from -70 mV to -60 mV) would make the cell easier to depolarize not less excitable…..the threshold for depolarization has been lowered
great channel
