Select the correct statement:
Options
- AAtrial Natriuretic Factor increases the blood pressure.
- BAngiotensin II is a powerful vasodilator.
- CCounter current pattern of blood flow is not observed in vasa recta.
- DReduction in Glomerular Filtration Rate activates JG cells to release renin.
Correct answer
D. Reduction in Glomerular Filtration Rate activates JG cells to release renin.
Step-by-step solution
The juxtaglomerular cells ( JGC ) secretes an enzyme rennin in response to a variety of stimuli such as decreased flow of filtrate and NaCl to macula densa, decrease in glomerular filtration rate ( GFR ), decreased stretch of JGC , and increased frequency of nerve impulses in the renal sympathetic nerves. Atrial Natriuretic Factor ( ANF ) decreases blood pressure as it is a powerful vasodilator. Angiotensin II is a powerful vasoconstrictor. The counter-current mechanism involves the exchange of water and electrolyt
