HIPERCALEMIA: como o K⁺ leva à despolarização da célula | Fisiologia Celular

In this video, I explain hyperkalemia in a logical, clear, and straightforward way, comparing a cell from a normal organism with a cell from an organism with hyperkalemia. The idea is for you to see, step by step, what changes in cell function when blood potassium is elevated, and how depolarization occurs. You will understand what happens to the K⁺ chemical gradient; the outflow of potassium by diffusion, the intracellular concentration of K⁺, the number of negative charges in the intracellular environment, the negativity along the plasma membrane; how this affects the membrane potential (Vm) and the cell's polarity. I hope you enjoy it!
