Question

complete the paragraph about atrial natriuretic peptide (anp) with the terms provided.

atria
renin
valves
increase
ventricles
decrease
cardiac cells
aldosterone

atrial natriuretic peptide (anp) is a hormone released by the _________ of the heart.

this release occurs when the _________ are stretched due to increased blood volume.

anp inhibits the release of _______ by the juxtaglomerular apparatus and the release of _______ by the adrenal cortex.

Explanation:

1. First blank: ANP is released by cardiac cells of the heart (specifically atrial cardiac cells, but "cardiac cells" fits the term options here as the atria are part of cardiac tissue).
2. Second blank: Stretching due to increased blood volume happens to the atria (the upper chambers of the heart), so "atria" is correct.
3. Third blank: The juxtaglomerular apparatus releases renin, and ANP inhibits renin release.
4. Fourth blank: The adrenal cortex releases aldosterone, and ANP inhibits aldosterone release.

Answer:

First blank: cardiac cells
Second blank: atria
Third blank: renin
Fourth blank: aldosterone
