Carbon Dioxide
levels of carbon dioxide in the blood. When carbon dioxide levels rise, the breathing center stimulates the muscles of respiration to increase breathing rate and depth. This helps to eliminate excess carbon dioxide and restore a balance in blood gas levels.
breathing is controlled by the level of co2 in the blood, (not due to the fact that there may be low amounts of o2), there are chemoreceptors that measure the pH level of the blood, remember that co2 can be transported in the blood as carbonic acid, thus this acid lowers the pH. if a low pH is detected, it sends nerve impulses to our brain, that stimulates us to breathe in an effort to get rid of the co2.

When carbon dioxide levels increase.
This is an automatic nerve flex and run by the autonomic nervous system.
The increase amount of carbon dioxide in the blood stimulates is called the autonomic nervous system. This is what controls breathing.
levels of carbon dioxide in the blood. When carbon dioxide levels rise, the breathing center stimulates the muscles of respiration to increase breathing rate and depth. This helps to eliminate excess carbon dioxide and restore a balance in blood gas levels.
