10. Comparison of systems controlling effective circulating volume and osmolality Water intake Brain: drinking behaviour Thirst Renal water excretion Short term : Blood pressure Long term : Na + excretion What is affected? Kidney Short term : heart, blood vessels Long term : Kidney Effector ADH RAAS, Symp NS, ADH, ANP Efferent Pathways Hypothalamic osmoreceptors Carotid sinus, aortic arch, renal afferent arteriole, atria Sensors Plasma Osmolality Effective Circulating Volume What is sensed?
