How does renal system function impact HTN?

The renal system plays a critical role in regulating blood pressure through mechanisms such as fluid balance, electrolyte regulation, and the renin-angiotensin-aldosterone system (RAAS). Impaired kidney function can lead to the retention of sodium and water, increasing blood volume and consequently elevating blood pressure. Additionally, dysregulation of RAAS can cause vasoconstriction and further hypertension. Therefore, any dysfunction in the renal system can significantly impact the development and management of hypertension.
