How Your Kidneys Keep Your Water
Your body's osmo receptors detect the water content in your blood and communicate with your kidneys to adjust water levels. If you drink too much water, the excess is removed by the kidneys. Conversely, dehydration triggers thirst and the release of anti-diuretic hormone to retain water. In just 40 seconds, the kidneys spring into action with a network of water channels that can absorb excess water. This intricate system of 'straws' in kidney cells ensures water is retained to maintain body balance efficiently.
