Practice: A 7-year-old boy throws a tantrum because his mom won’t buy him a Nintendo Switch. As part of the tantrum he holds his breath. He is unable to hold his breath until he passes out; the urge to breathe becomes overpowering and he starts breathing again. Which substance(s) accumulated in his bloodstream and activated his peripheral chemoreceptors to create this overpowering urge to breathe? (Choose all that apply.)
