Explain your answer with regards to the physiological mechanism?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
- (a) Define hyperventilation. (b) If you hyperventilate, do you retain or expel more carbon dioxide? (c) What effect does hyperventilation have on blood pH?arrow_forwardDivers sometimes hyperventilate before swimming underwater for an extended period of time. However, this could cause a sudden blackout while they are under the surface and lead to potential drowning. What caused the blackout to occur?arrow_forwardBased on the results from hyperventilation, does the concentration of oxygen or carbon dioxide have a greater influence on how long one can hold his breath?
