Cardiovascular disease is a major category of non-communicable disease. A sedentary lifestyle combined with a diet high in saturated lipids is a significant risk factor for coronary heart disease (CHD).
Which statement correctly explains how these lifestyle factors contribute to the development of coronary heart disease?
A diet high in saturated fat increases blood cholesterol levels, leading to layers of fatty material building up inside the coronary arteries, narrowing them and reducing oxygen delivery to the heart muscle.
A lack of physical exercise decreases the blood pressure in the coronary veins, causing them to collapse and block blood flow returning to the right atrium.
Excessive lipid consumption causes cholesterol to deposit directly in the heart chambers, preventing the heart valves from opening during ventricular systole.
Sedentary lifestyle factors increase the rate of aerobic respiration in adipose tissue, which consumes excess blood oxygen and deprives the heart muscle of oxygen.
