Question

Which one of the following is a permanent change in the
body that does not occur due to regular physical exercise?
Increase in the number of capillaries.
Increase in the abdominal size.
Increase in the blood cells.
Increase in the size of the heart.

Answer 1

The correct option is c) Increase in the size of heart.

Explanation:

• The number of capillaries is increased in a person who exercises regularly because more capillaries will be required to provide blood/oxygen to the body.
• The blood cells will increase as more blood supply will be needed by the body for exercise.
• The abdominal size increases as a result of physical exercise as the abdominal muscles are being used regularly.
• However, the size of the heart does not increase and remains the same.
