Non-electrolytes include many organic molecules such as glucose and urea.
They play a role in osmoregulation by affecting the osmotic balance without altering ionic strength.
Unlike electrolytes, non-electrolytes do not contribute to the electrical conductivity of bodily fluids.
In biological systems, non-electrolytes can influence water movement across cell membranes via osmosis.
Understanding the behavior of non-electrolytes helps in comprehending their role in cellular processes and overall fluid balance.
