Effect of exercise on the cardiovascular

Exercise has many effects on the cardiovascular system:

Long term effects include an increase in heart size because of the hard work exercise makes your heart perform, your heart becomes more accustomed it such hard work and therefore becomes more efficient at transporting blood around the body, because exercise makes it pump faster, so after exercise it is more efficient, due to it finding it can pump the same amount of blood around the body with less work and so can do it well because of the extra practice.

It stops you from becoming short of breath. It also helps strengthen your heart, the heart is a muscle and as you exercise the heart gets stronger. The fitter you are the less your heart has to work because your blood vessels will work better, as exercise will help the blood vessel linings to be more flexible. To lower your blood pressure will be as a stronger heart can beat slower but still pump large volumes of blood around the body. So, basically, you will have a lower resting heart rate.

 

Short term effects of exercise are that it helps to oxygenate your blood because more oxygen is needed in exercise, so the body inhales more oxygen and faster, therefore, it carries better supply oxygen to your organs in your body.

It increases your heart rate, and your stroke volume (The amount of blood pumped out of one ventricle of the heart in one pump) because it needs to get the oxygen out faster.
