Master Osmoregulation: The Collecting Duct and ADH fast ⚡ – clear explanations, OCR-aligned.
You’ll cover
• How the collecting duct contributes to osmoregulation by adjusting water reabsorption.
• The role of antidiuretic hormone (ADH) in controlling the permeability of the collecting duct.
• How changes in blood water potential regulate ADH release.
• The role of osmoreceptors and the hypothalamus in detecting changes in water potential.
• How ADH causes aquaporins to be inserted into collecting duct cell membranes.
What’s included
• Diagram showing water potential gradients in the kidney medulla.
• Diagram illustrating the structure of collecting duct epithelial cells.
• Diagram showing how ADH is released and transported to the kidney.
• Step-by-step diagram sequence showing how ADH increases water permeability in the collecting duct.
• Summary table outlining the key steps involved in ADH action and water reabsorption.
