One way exercise helps reduce risk of cardiovascular disease

• A. Keeps heart arteries healthy
• B. Increases appetite
• C. Reduces hydration
• D. Cure disease by itself

Answer: (A)

Regular exercise improves cardiovascular health by making blood vessels healthier and the heart work more efficiently. When you’re active, the lining of your arteries functions better, allowing them to relax and widen more easily. This lowers blood pressure and reduces the effort the heart must exert to pump blood. Over time, healthier arteries mean less risk of plaque buildup and cardiovascular events, which is why keeping the arteries from getting stiff or clogged is a primary way exercise cuts disease risk. The other options don’t explain this protective effect: exercise isn’t about increasing appetite for heart protection, it doesn’t reduce hydration to lower risk, and it doesn’t cure disease by itself.
