Short term BP regulation exerted through kidney by -

Ans. is 'a' i.e., ADH Regulation of blood pressureo Blood pressure is regulated by following mechanisms.Short term regulationLong term regulationShort term regulationThese mechanisms act immediately and correct the blood pressure quickly.These areBaroreceptor reflex: Works during BP range 79-150 mmHg.Chemoreceptor reflex: Works when BP below 80 mmHg. CMS ischemic response: This the only hope of survival when BP is below 40 mmHg.Hormonal release : These are -Antidiuretic hormone (ADH) : Increases water reabsorption in kidney.Angiotensin II: Causes vasoconstriction.Longterm regulationThis is the mechanism which takes long time for regulation.This mechanism is present in kidneys.This mechanism adjusts the BP by adjusting valume of extracellular fluid and blood.These mechanism are -Pressure diuresis.Pressure natreuresis. Renin-angiotensin-aldosterone system.Important facto Angiotensin II is involved in short term regulation,o But, full RAA system is involved in long term regulation.
