Which of the following are related to the control of human kidney functions?
$A.$ Osmoreceptors in the body get activated by excess loss of fluid,which results in the inhibition of $\text{ADH}$ secretion.
$B.$ $A$ fall in $\text{GFR}$ can activate the release of renin.
$C.$ Low blood flow to the atria stimulates the secretion of $\text{ANF}$.
$D.$ $\text{ANF}$ acts as a check on the renin-angiotensin mechanism.
$E.$ $\text{ADH}$ can also affect kidney function by its constrictory effect on blood vessels.
Choose the correct answer from the options given below:

$A$ fall in $GFR$ can activate the $JG$ cells to release ...... which can stimulate the glomerular blood flow and thereby the $GFR$ back to normal.
