Final answer:

The statement that heavy breathing following a bout of exercise is to get your oxygen levels of the blood back up to normal is True (Option A).

Step-by-step explanation:

When engaging in intense muscle activity, the body incurs an oxygen debt, which is the amount of oxygen required to restore ATP and creatine phosphate levels, convert lactic acid to pyruvic acid, and carry out other metabolic processes that were supported anaerobically during exercise. The increased breathing rate after exercise, known as hyperpnea, continues until this oxygen debt has been repaid, thereby restoring oxygen balance in the body.

It is important to note that a higher breathing rate also helps in removing excess carbon dioxide produced during rigorous physical activity. Furthermore, hyperpnea is not only a response to decreased oxygen but also involves neural control and response to high carbon dioxide and low pH levels in the blood.

Thus, the correct option is A.
