Question 1 of 5
Which gas has an insignificant role in the regulation of respiratory rhythm?
Correct Answer: A
Rationale: According to the information provided, the role of oxygen in the regulation of respiratory rhythm is insignificant. While oxygen levels are important for the overall functioning of the respiratory system, the primary factors that influence the respiratory rhythm are changes in carbon dioxide (CO₂) and hydrogen ion concentrations. Oxygen levels are primarily monitored by the peripheral chemoreceptors for maintaining oxygen homeostasis, but they do not play a significant role in directly regulating the respiratory rhythm.
