Several hormones are involved in the complex physiology of urinary filtration & blood pressure, an example of this would be the expected increase in blood levels of ANP after the heart detects:
a. Blood pressure is increased
b. increase in preload of heart
c. Walls of atria stretched
D. All of the above is correct
Increase in blood levels of ANP occurs after the heart detects -
Blood pressure is increased , Increase in preload of the heart , Walls of atria stretched
When the blood flow in Atrias of heart increases , the preload is increased which stretches the walls of atria. It is due to the increased blood pressure.
When the ANP is secreted , it induces vasodilation and release of Na+ ions in filtrate . Thus it reduces the increased blood pressure.
So all the above options are correct.
