STANDARD Zoology Regulation of Kidney Function MCQ Question
A fall in glomerular filtration rate (GFR) activates
Juxta glomerular cells to release renin
Adrenal cortex to release aldosterone
Adrenal medulla to release adrenaline
Posterior pituitary to release vasopressin
Correct Answer
Detailed Explanation
When there is a fall in glomerular filtration rate, it activates the juxta glomerular cells to release renin. This stimulates the glomerular blood flow, thereby bringing GFR back to normal. Renin brings the GFR back to normal by the activation of the renin-angiotensinogen mechanism.
