Question

Quizplus · Accepted Answer

Decreased blood volume leads to decreased blood pressure, which stimulates the release of renin from the kidneys (step C). Renin then leads to the formation of angiotensin II (step D). Angiotensin II causes constriction of blood vessels, leading to an increase in blood pressure (opposite of step C). Therefore, the correct sequence is: C = ↓ blood pressure; D = ↑ renin release by kidneys; E = ↑ angiotensin II formation. Choice B correctly represents this sequence.
