- Which of the following statements regarding control of respiration is TRUE? At high altitude, a decrease in PC02 of the blood stimulates an increase in ventilation. An increase in the HCO3- concentration in blood stimulates ventilation. A slight decrease in arterial PO2 is a stronger stimulus for increased ventilation than is a comparable decrease in arterial PCO2. The most important signal for regulating ventilation is the H+ concentration of arterial blood. Increased concentrations of lactic acid stimulate ventilation primarily by acting on peripheral chemoreceptors.arrow_forwardHow do you regulate the amount of oxygen that enters and the amount of carbon dioxide that leaves your body? Which direction are gases moving in the partial pressure gradient, and why are they doing so?arrow_forwardDaniel, the swimmer with the fastest time on the college swim team, routinely hyperventilates before a meet, as he says "to sock some more oxygen into my lungs so I can swim longer without having to breathe." "Furthermore, my heart won't have to adjust it's output". First of all, what basic fact about oxygen loading has Daniel forgotten (a lapse leading to false thinking)? Do you think that hyperventilation will provide him with enough oxygen to increase his endurance during the race?arrow_forward
- After light exercise, the oxygen consumed in recovery is approximately equal to the oxygen deficit, which is the amount of additional oxygen that would have been consumed had oxygen consumption reached steady state immediately. How is the oxygen consumed in recovery used?arrow_forwardWhat are the two ways that oxygen can be transported in the blood?arrow_forwardWhat can cause a sudden decrease in oxygen saturation?arrow_forward
- How can the quantity of oxygen that dissolved in the plasma of the blood be calculated?arrow_forwardWhy should the total oxygen delivery be much lower than indicated by a particular PaO2 value?arrow_forwardWhat mainly differentiates myoglobin from hemoglobin if they both have oxygen-carrying functions?arrow_forward
