Alveolar hyperventilation leads to a decreased partial pressure of arterial carbon dioxide (PaCO2). The decrease in bicarbonate is accompanied by the deviation of serum pH below 7.35.
It is called Respiratory Acidosis. It´s blood pH imbalances. Muscle fatigue is associated with a rapid increase in the production of metabolic acids. Tolerance to high intensity exercise may be limited by the body's ability to dampen the decrease in intracellular (muscle) and extracellular (blood) pH, that is, the intrinsic buffer system.
The answer is aldosterone. This hormone determines the rate
of re-absorption of H+ ion and bicarbonate ions by the kidneys. Due to high
levels of bicarbonate being produced by the pancreas, the blood will be basic.
The kidneys will therefore be signaled to excrete more bicarbonate ions.
Fossil Fuels pollute the earth and add to the greenhouse effect which in turn breaks down our atmosphere. Which is global warming (broken down atmosphere letting in radiation)
