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? A. Derek is more likely to have constricted blood vessels and would be more likely to suffer from high blood pressure than Aaron.
B. Derek is more likely to have relaxed blood vessels and would be less likely to have heart disease than Aaron.
C. Aaron is more likely to have constricted blood vessels and would be more likely to suffer a heart attack or stroke.
D. Aaron is more likely to have relaxed blood vessels, though they would be equally likely to suffer from a hardening of their arteries.
Option A- Derek is more likely to have constricted blood vessels and would more likely suffer from high blood pressure than Aaron
Explanation:
This is a good example of non-clinical factors in the cause of disease. Exercise improves the utilization of energy reserves. It facilities proper circulation of oxygen and other components through out the body. The higher energy demands of exercise reduce the chances of fat deposition on the walls of the arteries. The other factor stress is known to increase the heart rate ad blood pressure. Chronic increase in blood pressure increases the chances of cholesterol plaque to be deposited on the arteries.
