Two identical twins, derek and aaron, grew up in the same household without any health problems. for most of his life, derek had a high-stress job and did not have time for exercise. aaron, on the other hand, led a low-stress lifestyle and exercised regularly. how would their cardiovascular systems compare?
From the description,it is clear that Aaron;s cardiovascular system is healthier than Derek. The cardiovascular system can be kept healthy by doing exercise to help the heart pump the blood to be distributed to your body. Also, stress causes depletion in hormones which will make your heart and brain less functional.
