To help prevent atherosclerosis, a person needs to reduce/eliminate the modifiable risk factors that one has (high blood pressure, high blood glucose levels, high blood cholesterol levels, cigarette smoking, obesity, lack of exercise).
One should eat a healthy diet low in saturated fat and rich in fruits and vegetables.
If emotional stress is a problem, one should find ways to reduce or control it.
Fortunately, taking steps to tackle some of the risk factors helps to modify other risk factors. For example, exercise helps a person to lose weight, which in turn helps to lower cholesterol levels and blood pressure.
Circulatory System
Circulatory System, or cardiovascular system, in humans, the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products. Among its vital functions, the circulatory system increases the flow of blood to meet increased energy demands during exercise and regulates body temperature.
