Osmosis and Medicine: Why Is Saline Used for Intravenous (IV) Fluids?

How do various solution concentrations affect water flow into and out of cells? In this simulation, you’ll investigate the principles of osmosis and will discover how maintaining osmotic balance with saline IV fluids is essential for cellular homeostasis and patient safety.
