A decrease in breathing rate reduces the amount of carbonic acid removed and causes an increase of hydrogen ions in the blood.Group of answer choicesTrueFalse

Which of the followig would increase the pH of the blood?   high intensity exercise resulting in the production of CO2. decreased ventilation causing a build up of CO2. increased ventilation at the lung to remove CO2. a higher ventilation to perfusion ratio (V/Q) in the lung.

An increase in the level of carbon dioxide in the blood will:Question 47Answera.decrease alveolar ventilation.b.decrease pulmonary ventilation.c.decrease the rate of breathing.d.increase the pH of arterial blood.e.increase the rate of breathing.

Which of these factors would cause an increase in heart rate?Multiple ChoiceIncreased parasympathetic stimulationA decrease in carbon dioxide in the bloodStimulation of baroreceptors in the aortaExcess potassium ionsA decrease in blood pH

When the pH of the blood becomes more acidic, the respiratory center Group of answer choicesstops our breathing altogether.increases the rate and decreases the depth of breathing.increases the rate and increases the depth of breathing.decreases the rate and increases the depth of breathing.decreases the rate and decreases the depth of breathing.

Hyperventilation (rapid breathing) occurs in response to respiratory acidosis because hyperventilation:A.increases blood pH by decreasing CO2 concentrations.B.increases blood pH by decreasing HCO3- concentrations.C.decreases blood pH by decreasing CO2 concentrations.D.decreases blood pH by decreasing HCO3- concentrations
