High exposure to carbon dioxide (CO2) primarily affects the body by increasing the respiratory rate. This occurs because CO2 is a byproduct of metabolism that the body needs to eliminate. When CO2 levels in the blood rise, it leads to a condition called hypercapnia, which triggers the body to respond by increasing the rate and depth of breathing in an effort to expel the excess CO2 and restore normal levels.

The body continuously monitors carbon dioxide levels through chemoreceptors, which are sensitive to changes in blood pH, oxygen, and carbon dioxide concentrations. An increase in CO2 leads to a lower pH (more acidic blood), which signals the respiratory center in the brain to enhance breathing to bring in more oxygen and expel more CO2. This physiological response is crucial for maintaining homeostasis, as elevated CO2 can lead to symptoms such as headaches, confusion, and, in extreme cases, loss of consciousness or respiratory failure.

Engaging with the mechanisms of respiratory regulation and the body's need to maintain proper gas exchange highlights the critical importance of CO2 management in overall health.
