In this con- dition, there is a potent stimulus for renal Na retention that clearly cannot be the ECF volume. When EABV is diminished, the degree of fullness of the arterial system is less than normal and tissue blood flow is Ingested Na+ inadequate. Arterial baroreceptors in the carotid sinuses 100 300 mEq/day and aortic arch sense the decreased arterial stretch.
