Respiratory rate is most sensitive to the effects of which ion?

Question

Quizplus · Accepted Answer

Changes in the level of H+ ions in the blood have a direct impact on respiratory rate. This is due to the role of the respiratory system in regulating acid-base balance in the body. An increase in H+ concentration (acidosis) stimulates faster and deeper breathing to eliminate CO2 (which can combine with water to form H+ ions) and reduce the acidity of the blood. Conversely, a decrease in H+ concentration (alkalosis) can result in slower breathing to retain CO2 and increase the blood's acidity. Therefore, H+ ions are the most sensitive to the effects of respiratory rate, and changes in their levels are closely monitored and regulated by the respiratory system.
