Select the factor in the arterial blood that has the largest effect on increasing the rate of respiration. A) increase in the hydrogen ion concentration in the kidneys B) increase in the hydrogen ion concentration in the arterial blood C) any decrease in the partial pressure of carbon dioxide D) any decrease in oxygen's partial pressure E) detection of CO₂ by central chemoreceptors

Question

Quizplus · Accepted Answer

An increase in hydrogen ion concentration in the arterial blood, known as respiratory acidosis, stimulates an increase in respiration rate in order to remove excess carbon dioxide and decrease the concentration of hydrogen ions. This is the most significant factor in increasing the rate of respiration. The other factors listed may also have an effect on respiration rate, but to a lesser extent.
