how do kidneys response to a decrease in blood pressure?!
Question:
Answers:
a severe change/decrease in blood pressure (BP) would hypoperfuse the organs of the body. Hypoperfuse means there is decrease blood nutrients (blood inadequately supply organs with proper nutrients (oxygen).
there would be decreased blood flow to the kidneys, thereby producing less urine. without blood supply, organs become ischemic and start to dysfunction. If it is prolonged, there would be permanent damage.
High blood pressure could also damage our kidneys. it is always best to maintain an optimal blood pressure.
Other Answers:
The kidneys hold on to salt and water, trying to improve the blood pressure.
kidney secretes Renin, that cleaves Angiotensinogen (from Liver) circulating in bllod into Angiotensin I and gets converted by ACE (in lungs) into Angiotensin II which will help release Vasopressin (conserve water in kidneys), retain salt, increase thirst and cause arteriole constriction (increase resistance).
