alleryA fall in GFR activates the JG cells to release
Ainsulin
Bthyroxine
Crenin
Dmelatonin
Answer & Solution
Correct answer: C. renin
1. The kidney has a built in mechanism to regulate its own filtration rate.
2. The juxta glomerular apparatus senses the fall in GFR.
3. JG cells then release renin.
4. Renin stimulates glomerular blood flow and brings GFR back towards normal.
5. Insulin, thyroxine and melatonin come from the pancreas, thyroid and pineal gland respectively.
