Kidney Function & ADH Simulation

ADH and Collecting Duct Simulation

ADH Level (0 = None, 100 = High):

Current ADH Level: 20%

Water lost/released as urine

Water reabsorbed

ADH (antidiuretic hormone) helps the kidneys retain water by making the collecting duct walls permeable to water.

When you're dehydrated, ADH levels rise. Water is reabsorbed from the duct into the bloodstream.

When ADH is absent, ducts are impermeable. Water stays in the duct and becomes urine.

This process is part of osmoregulation, balancing water and salts to maintain homeostasis.
