If the pH, PO2, and PCO2 of arterial blood do not change during the light to moderate phase of the progressive test, what are the signals to the respiration center that drive breathing in proportion to the workload? A) stretch receptors located in the lungs B) neural input from higher brain centers C) feedback from chemoreceptors located in the carotid bodies D) feedback from chemoreceptors located in the aortic bodies

Step 1
The question is asking about the signals that drive breathing in proportion to the workload during light to moderate exercise, specifically when the pH, PO2 (partial pressure of oxygen), and PCO2 (partial pressure of carbon dioxide) of arterial blood do not Show more…

Which of the following factors does not increase the rate of breathing by influencing the chemoreceptors? a. an increase in $P_{C O_{2}}$ in the arterial blood b. an increase in $P_{O_{2}}$ in the arterial blood c. a decrease in the $\mathrm{pH}$ of the arterial blood d. a decrease in $\mathrm{P}_{\mathrm{O}_{2}}$ in the arterial blood e. an increase in the $\mathrm{H}^{+}$ concentration in the arterial blood
Which of the following is/are true for the depth and rate of breathing (Select all that apply): Increased carbon dioxide levels cause an increase in pH Central chemoreceptors in the brain stem respond to hydrogen ions in CSF Adjustments to the ventilation can return the plasma pH back to the normal range of pH 7.35-7.45 Decreased carbon dioxide levels cause a decrease in pH Brain stem respiratory centers control respiratory muscles
