Final answer:
The correct function that is NOT a role of angiotensin II is stimulating renin secretion, as renin leads to the formation of angiotensin II.
Step-by-step explanation:
The function that is NOT one of the roles of angiotensin II is to stimulate renin secretion. This is because renin secretion leads to the production of angiotensin II, not the other way around. Angiotensin II indeed has several key roles which include causing vasoconstriction, stimulating the release of aldosterone and antidiuretic hormone (ADH), and increasing thirst, which collectively act to stabilize blood pressure and blood volume.
