Nah, we're just kidding. That's not actually a colored scanning electron microscope shot peering down into a human sweat gland.
Can you imagine?
No, it's looking back from the inside of the human body to your exit point as it closes up mere seconds before you return to full size in an explosion of Martin-meat. Otherwise that is an entirely accurate portrait of what your sweat gland looks like. It's also probably the reason why Ant-Man drinks so much after every mission.
At Normal Size ...
Wine is the proper way to induce inebriation in situations where other drinks, like beer or psychedelic mushroom tea, might be frowned upon. You know, like dinner at your boss's house, or ... well, no, that's pretty much the only time you should drink wine. It is the lady and/or gentleman's preferred stupid-making body-poison, and part of that has to be its look: smooth, uniform, and a deep, elegant crimson, like the blood of some majestic mythical creature. A unicorn, perhaps.
Seriously, this vampire fetish defines our whole diet.
