Falling arterial blood pressure promotes ________. falling arterial blood pressure promotes ________. enhanced sodium ion loss in urine vasoconstriction vasodilation enhanced water loss in urine

Respuesta :

Atrial natriuretic peptide released by certain atrial cells in response to rising BP or volume, causes systemic vasodilation and inhibits renin, aldosterone, and ADH release. Hence, it enhances Na+ and water excretion, reducing BP and bv.  Falling arterial pressure promotes vasoconstriction and conserves Na+ and water.
