Flashing lights, electric impulses traveling at mindboggling speeds, everything around is aglow — no, it’s not a thunderstorm, it’s you. You’ve just yawned, sending a powerful surge of energy through your body. Wanna know how humans breathe, how the lungs work, and how oxygen travels through the body? This is what we're talking about today!

Well, first, the air enters the mouth and nostrils. One nostril, in fact, because the other is naturally resting. Are you eating something there? Just don’t try to make another breath while swallowing that pizza — only babies are capable of that and inhaling at the same time. Okay, there's the pharynx, where air and food come together. It’s a kinda sorting stage. Epiglottis makes sure that food goes where it belongs, to the esophagus. Next are the larynx, the trachea, and finally to the two bronchi, one going to each lung.
