CO2 and O2 play an important role in the regulation of our breathing. The correct balance of these two gases in the body is essential for normal breathing.
CO2 and Breathing
Carbon dioxide (CO2) is a waste gas produced by the body during the process of energy production. When CO2 concentration in the body increases, it causes the respiratory center in the brain to be stimulated, which causes us to take deeper and faster breaths to expel the excess CO2. This is known as hyperventilation.
O2 and Breathing
Oxygen (O2) is the gas we need to survive. Low levels of oxygen in the body, known as hypoxia, can lead to difficulty breathing, dizziness, and even death. The body's oxygen levels are monitored by the respiratory center, which will cause us to take deeper and faster breaths when it senses a decrease in oxygen levels.
Conclusion
CO2 and O2 both play an important role in the regulation of our breathing. When CO2 levels increase, the brain is stimulated to take deeper and faster breaths to expel the excess CO2. On the other hand, when oxygen levels decrease, the brain is stimulated to take deeper and faster breaths to increase oxygen levels. Therefore, both CO2 and O2 play a role in controlling our breathing.
