Because of _______________, renin is released by _____________. Select one: a. ADH activity; mesangial cells b. systemic blood pressure increases; granular cells c. aldosterone activity; macula densa d. systemic blood pressure decreases; granular cells
Solutions
Expert Solution
Answer :- D. Systemic blood pressure decreases; granular cells
Explanation :- granular cells also known as JG cell a modified muscle cell that secrete renin ( endocrine hormone ) in response to Drop in afferent arteriole blood pressure.
After the releasing of renin it goes into the blood and initiate a chemical reaction .
They covert Angiotensinogen into Angiotensin 1after that Angiotensin-1 combine with another enzyme called, Angiotensin converting enzyme which is found in the lungs and blood stream and convert into the Angiotensin-2 which stimulates sympathetic nervous system that cause vasoconstriction result is afferent arteriole pressure increases...Thanks dear student
