If a patient experiences extreme dehydration due to heatstroke, which consequence relating to the collecting ducts and ADH secretion follows?

💡 Explanation

In dehydration, the body increases ADH secretion, stimulating aquaporin insertion in collecting duct cells. This increases water reabsorption into the bloodstream. Therefore, increased aquaporin insertion occurs, rather than sodium excretion; decreased blood volume would exacerbate the condition.
