💧 Antidiuretic Hormone and Water Balance: How the Body Regulates Fluid Osmolality

Explore how hypothalamic osmoreceptors, the posterior pituitary, and kidney aquaporin-2 channels work together to keep blood plasma osmolality within a tight, life-sustaining range.

The simulation shows, in an interactive 3D model, how rising or falling plasma osmolality changes hypothalamic osmoreceptor firing, posterior pituitary ADH release, and the resulting insertion of aquaporin-2 channels in kidney collecting ducts to control urine concentration.

🔬 What It Demonstrates

🎮 How to Use

Adjust hydration status or simulate factors like dehydration or alcohol intake using the sliders, then watch osmoreceptor activity, circulating ADH levels, and urine osmolality update in real time across the hypothalamus-pituitary-kidney axis.

💡 Did You Know?

A single molecule of ADH can trigger the insertion of thousands of aquaporin-2 channels into a kidney cell membrane within minutes, allowing the body to shift from producing dilute to maximally concentrated urine remarkably quickly.
