Answer 2

Answer:

It is a false statement that the breathing rate of a person decreases during heavy exercise.

Explanation:

• The respiration of muscle cells is more during exercise.
• When we perform physical activity, the heart rate increases.

When we exercise our body produces more carbon dioxide and uses more oxygen. This is due to the fact that our muscles work harder.

So, the breathing rate increases to absorb more oxygen into the blood and remove more carbon dioxide. The rate of breathing increases from $15$ times per minute during rest to $40-60$ times per minute during exercise.

Hence, it is a false statement that the breathing rate of a person decreases during heavy exercise.
