Is your breathing rate more sensitive to levels of carbon dioxide or of oxygen in the blood?

Oxygen
is continually consumed to produce energy. Only increased breathing can meet the
demands of increased activity, as explained by exercise physiologists at Eastern
Kentucky University. Your brain balances your levels of blood oxygen, O2, and carbon
dioxide, CO2, the end-product of oxygen use, to match your breathing to your exercise
demands. This is automatic and requires no conscious control.

The breathing center in the brain is most sensitive to the?
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.
What has the greatest stimulation on the respiratory center in the brain?
blood carbon dioxide levels
Levels of oxygen and carbon dioxide in the blood are tested by?
Oximetry.
What is the most powerful respiratory stimulus for breathing in a healthy person?
Of all of the chemicals influencing respiration, CO2 is the most potent and the most closely controlled. Normally, arterial Pco2 is 40 mm Hg and is maintained with in + - 3 mm Hg of this level by an exquisitely sensitive homeostatic mechanism that is mediated mainly by the effect that rising Co2 have on the central chemoreceptors of the brain stem.
How does the process of photosynthesis affect carbon dioxide concentrations in the atmosphere during a typical year?
Photosynthesis uses carbon dioxide as a raw material where carbon dioxide is fixed into organic molecules. This process lowers the level of carbon dioxide in the atmosphere. The seasonal fluctuation of carbon dioxide levels during a year may be caused by increased photosynthesis during spring and summer.

How is carbon dioxide levels replenished?
breathing
What happens to the blood concentration level of carbon dioxide following increased breathing?
With increased breathing, levels of carbon dioxide in the blood drop and levels of oxygen rise.
The central chemoreceptors are primarily sensitive to blood levels of?
Carbon dioxide and hydrogen ions
What symptoms are associated with low levels of carbon dioxide in your blood?
You will be hyperventilating or will be breathing fast.
Which breathing pattern results in decreased levels of carbon dioxide at the cellular level?
Hyperventilation
Why are lungs not suitable for breathing water?
Air breathers are more sensitive to changes in carbon dioxide concentration than to changes in oxygen. Regulation of ventilation is normally driven by receptors that are sensitive to dissolved carbon dioxide levels and the acidity (pH) of the blood.

Is breathing controlled by changes in the chemistry of the blood?
In short, yes. The main control of respiration is actually the level of carbon dioxide in your blood. When carbon dioxide levels rise, a chemical reaction occurs that causes the acidity levels of your blood to rise. This is detected by chemorecepters that stimulate you to breathe. On the other hand, if you breathe too fast and carbon dioxide levels drop, your body will slow down it's breathing. There are several other processes that help regulate breathing, but carbon dioxide levels are by far the most important.
When there is an increase in carbon dioxide in the blood what occur?
There is a part of the brain called the medulla oblongata which detects increased carbon dioxide levels in the blood and triggers the breathing reflex. Breathing then allows the excess carbon dioxide to escape by way of the lungs, as oxygen is acquired.
What is one factor that stimulates the brainstem to increase the breathing rate?
When carbon dioxide levels increase.
What are the two important gases that staying us alive?
Oxygen and carbon dioxide are critical for us to breath. Oxygen is the gas that keeps us alive. Increased levels of carbon dioxide is what enables us to keep breathing. When carbon dioxide increases in our system we respond by breathing.
Does the breathing control center in the brain monitor the rising CO2 levels in the blood?
Quite so. The brain stem detects high levels of carbon dioxide and triggers breathing.
