Correct answer and explanation

Correct answer: Juxtaglomerular cells of the kidney

Explanation: āœ… Correct Answer: A) Juxtaglomerular cells of the kidney šŸ“š Explanation: When human blood pressure or blood sodium levels drop significantly, the highly specialized juxtaglomerular cells located in the kidneys immediately secrete an enzyme called renin. Renin aggressively triggers the renin-angiotensin-aldosterone system (RAAS), which aggressively constricts blood vessels and retains water to rapidly restore normal blood pressure.
