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.
