In response to such condition body response by activating the renin-angiotensin-aldosterone system. Activation of this system is taking place by physiological change such as sudden decrease in blood circulation and blood pressure. This system increase water and sodium retention so blood pressure becomes normal so blood can flow to essential organs.
The renin-angiotensin-aldosterone system also helps in creating vasoconstriction with the help of angiotensin II.
