During a state of severe dehydration, which of the following describes the synergistic action of ADH and aldosterone on the nephron?
- Aldosterone increases the osmotic drive for water reabsorption, while ADH provides the pathway for that water to move.
- ADH lowers blood pressure to cut glomerular filtration, while aldosterone raises excretion of excess salts.
- Aldosterone acts on the proximal tubule to reclaim glucose, while ADH acts on the loop of Henle to secrete urea.
- Both hormones act directly on the glomerular capillaries to lower net filtration pressure and thereby conserve circulating blood volume.
