What is the difference of high and low potassium levels in the extracellular fluid during secretion in the urinary system?

Maddie H.
Answer:

If potassium levels are low in the extracellular fluid then the nerve and muscles cell will hyper-polarize and reduce excitability. If potassium levels are high in the extracellular fluid membrane excitability will increase especially in heart which can cause cardiac arrhythmias.
