Explanation:
Detailed explanation-1: -Chronic activation of the renin‐angiotensin‐aldosterone system (RAAS) promotes and perpetuates the syndromes of congestive heart failure, systemic hypertension, and chronic kidney disease.
Detailed explanation-2: -On its own, renin doesn’t affect your blood pressure. Instead, it works together with angiotensin and aldosterone to accomplish this. Angiotensin narrows your blood vessels and aldosterone causes your kidneys to retain water and salt. This increases the amount of fluid in your body and raises your blood pressure.
