Which of the following statements is TRUE? Central chemoreceptors in the brain detect changes in H+ (pH). When blood needs to unload carbon dioxide, there are more action potentials in the cardioinhibitory center. Carbon dioxide dissolved in the blood does not affect pH. T cells prevent macrophages from engulfing pathogens.

Which of the following statements is false? As an organism's activity level increases, the level of CO2 in the blood will increase and stimulate faster or stronger breathing. Breathing is controlled by both voluntary and involuntary mechanisms. Chemoreceptors involved in the homeostatic control of breathing are located in the brainstem and the carotid and aortic bodies. Decreasing levels of oxygen in the blood are detected by chemoreceptors in the brainstem.
Qbs E.
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
Sri K.
