Answer to Question #276274 in Human Anatomy and Physiology for Water

Question

2. A patient is reported with low blood pressure.  

Briefly or diagrammatically explain the renal response to  

this condition. Explain the involvement of important  

hormones in the process.

Answer 1

When a person has low blood pressure, the kidney will synthesize and release renin. Renin, in turn, will convert angiotensinogen to angiotensin I. angiotensin I will also be converted into biologically active angiotensin II by the ACE produced in the lung. Aldosterone is one of the linked hormones, and they create a system of renin-angiotensin-aldosterone. This system is activated when a person has low blood pressure due to a hemorrhage or a decrease of blood flow in the kidney due to blood volume loss.
