Question

question 10 (mandatory) (3 points)
how does aerobic exercise help prevent cardiovascular diseases?
it helps you burn more calories, which reduce the potential for fat growth.
it warms your blood, making it more fluid, so that your heart can pump more efficiently and slowly, creating less stress on the heart.
it increases your blood pressure, which allows your heart to increase fat cells before they form plaque on the artery walls.
it makes your heart beat faster to supply more oxygen, which makes the heart stronger and enables it to pump blood more efficiently

Explanation:

Aerobic exercise makes the heart beat faster to supply more oxygen. This strengthens the heart muscle. A stronger heart can pump blood more efficiently. Efficient blood - pumping reduces the workload on the heart over time, which is beneficial for preventing cardiovascular diseases. Burning calories (while a benefit of exercise) is more related to general weight management rather than the direct cardiovascular - prevention mechanism related to the heart's function. Warming blood in the way described is not a typical scientific explanation for aerobic exercise's cardiovascular benefits. Increasing blood pressure is generally a risk factor for cardiovascular issues, not a preventive one.

Answer:

It makes your heart beat faster to supply more oxygen, which makes the heart stronger and enables it to pump blood more efficiently.
