Prolonged hypertension primarily affects which body system?

• A. Cardiovascular system
• B. Respiratory system
• C. Renal system
• D. Nervous system

Answer: (A)

Prolonged hypertension places persistent high pressure on the circulatory system, so the cardiovascular system is the primary affected. When blood pressure remains elevated, the heart has to pump harder (increased afterload) and the vessels endure ongoing stress, leading to changes such as left ventricular hypertrophy and vascular remodeling. This elevates the risk of heart disease, heart failure, and stroke, and it can drive damage to arteries and organs over time. The kidneys and brain can suffer as downstream consequences of this vascular stress, but the main target of sustained high pressure is the heart and blood vessels. The respiratory system is not directly driven by high blood pressure in the same way.
