A) "The release of the catecholamines epinephrine and norepinephrine cause an increase in blood pressure."
B) "The release of renin causes an increase in blood pressure."
C) "The release of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) cause an increase in blood pressure.
D) "The synthesis and release of adrenomedullin causes an increase in blood pressure."

A) A drop in renal perfusion stimulates renin release. Renin converts angiotensinogen to angiotensin I, which is then converted to angiotensin II in the lungs. ANP and BNP are released from the atrial cells, not the renal system. The catecholamines epinephrine and norepinephrine are released from the adrenal cortex, not from the kidneys.
B) A drop in renal perfusion stimulates renin release. Renin converts angiotensinogen to angiotensin I, which is then converted to angiotensin II in the lungs. ANP and BNP are released from the atrial cells, not the renal system. The catecholamines epinephrine and norepinephrine are released from the adrenal cortex, not from the kidneys.
