Question 5

which hormones are secreted when sodium is high?

ANP(atrial natriuretic peptide) and BNP(brain natriuretic peptide)

Question 6

what is ANP and BNP?

Answer 6

-both are hormones that act to suppress SODIUM levels and WATER by kidney excretion or decrease renin release and inhibiting the secretion of aldosterone and ADH.
-ANP is secreted when atrium stretches
-BNP is secreted when ventricles stretch
