The function of ANP is antagonistic to the renin-angiotensin-aldosterone-system.

a. True

b. False

A. True

Explanation:

The renin-angiotensin-aldosterone system stabilizes blood pressure and volume. The system constricts arteries and increases the amount of blood that the heart pumps, as well as the reabsorption of sodium (Na+) by the nephrons. Also, it decreases the glomerular filtration rate. All this increases blood volume and pressure.

On the other hand, ANP decreases blood volume and pressure by increasing the glomerular filtration rate and decreasing reabsorption of sodium by nephrons. Finally, this hormone inhibits the release of renin, aldosterone, and ADH.
