WebThe ability of mammals to reabsorb water is dependent on the medullary osmotic gradient created by the loop of Henle, which drives the reabsorption of water from the collecting duct. A higher osmotic gradient enables more water to be reabsorbed, thus producing a concentrated urine. WebIn juxtamedullary nephrons, which region sets up the medullary osmotic gradient? A. collecting duct B. Bowman's capsule C. loop of Henle D. proximal tubule E. distal tubule …

Hypovolemia, on the other hand, is a potent but much less sensitive stimulant. Greater than ~7% of volume depletion is needed to trigger AVP release. Once triggered, the rise can be sustained and amounts to a large magnitude.
