Gas exchange Memes

The desperation of blood cells trying to negotiate with lungs is peak cellular drama. Here we have blood cells attempting to convince lungs that CO₂ is just "O₂ with an extra candy" - which is like saying a hand grenade is just a stress ball with spicy filling. The lungs, represented by two golden retrievers with that signature "I have no idea what's happening but I'm happy to be included" expression, are clearly not buying this biochemical nonsense. This is basically every gas exchange negotiation in your body, except instead of complex respiratory physiology, it's just dogs staring blankly at chemistry lies. Your circulatory system: where desperate blood cells try to pass off their metabolic waste as "fancy oxygen" since 1.5 billion years ago.
