Explain why high blood pressure can be both a cause and consequence of renal damage.
What will be an ideal response?
Answer: High blood pressure can damage the arterioles leading to the kidney, which may be followed by local hypoxia due to poor blood flow and tissue death. If blood flow to the kidney is poor, the kidney releases renin, which raises angiotensin II levels, increasing blood pressure.
