Question

Regarding fluid shifts and dehydration, when adh secretion increases to regulate sodium balance by means of increased water retention without additional water consumption (i.e., you lost water but retained electrolytes and didn't drink water], the end result is:regarding fluid shifts and dehydration, when adh secretion increases to regulate sodium balance by means of increased water retention without additional water consumption (i.e., you lost water but retained electrolytes and didn't drink water], the end result is:increased na+ levels in ecf compared to the original condition.decreased ecf volume compared to the intermediate condition.water shifting into the icf.decreased sodium concentrations.

Answer 1

Antidiuretic hormone (ADH) is a peptide hormone secreted by the hypothalamus that allow water reabsorption to occur and regulate sodium balance. When there is an increase in ADH secretion, the sodium levels in extra cellular fluid (ECF) will also increase as compared to the original condition.
