Art, 75 years old, has advanced arteriosclerosis and is suffering from a number of manifestations associated with arteriosclerosis. Over the past several years he has developed hypertension and he is beginning to show signs of renal failure. Which of the following are consistent with his condition?
A) Increased resistance to blood flow
B) Increased renin secretion from the kidneys
C) Increased aldosterone secretion from the adrenal cortex
D) Increased angiotensinogen formation
E) All of the choices are correct.
Arteriosclerosis
A general term describing the thickening and hardening of arterial walls that can restrict blood flow.
Renal Failure
A medical condition where the kidneys lose their ability to filter waste products from the blood, leading to accumulation of toxins.
Hypertension
A chronic medical condition in which the blood pressure in the arteries is persistently elevated.

Final Answer :
E
Explanation :
All of the choices are consistent with Art's condition. Arteriosclerosis can lead to increased resistance to blood flow due to the narrowing of arteries. This can cause the kidneys to secrete more renin, which in turn increases aldosterone secretion from the adrenal cortex and stimulates the formation of angiotensinogen, all part of the body's compensatory mechanisms to maintain blood pressure and fluid balance, which can be disrupted in conditions like arteriosclerosis.
