Your friend Lolo wants to train for her first-ever 5k running race, and she is already thinking about her breathing (yes, she's overthinking this). At rest, she typically takes thirteen 400 mL breaths per minute and she has an anatomical deadspace of 125 mL. Lolo knows that she will have to change her breathing when she runs, but she's trying to figure out what would be most effective at getting O2 into her alveoli and down to her leg muscle. She heard that you're taking this human physiology course, and so she comes to you to ask what you think. You tell her the most effective way to increase the PO2 in her alveoli is...
