Answer:
Angiotensin II atrial natriuretic peptide(ANP) lowers blood pressure.
Explanation:
Increase in plasma volume leads to increase in blood pressure and a decrease in plasma level also leads to a decrease in the blood pressure. ANP is an enzyme which stimulates the decrease in blood levels through certain factors thereby causing a decrease in the blood pressure.
Meanwhile ADH stimulates increase in blood plasma levels thereby increasing the blood pressure.
