Shape of the Heart

This kills the person.
- I think taking the heart out is the part that kills them, unless perhaps you reverse origami it while it's still attached
- Caaaaaaaaaaaaaarrrrrllll!!
  
  In case anyone is like me and only knows this from years ago, the creator filmcow is still around and has been making tons of great content all these years (check out vulo lives). I think he's even crowdfunding a new ending to the llamas with hats series at the moment which I'm pretty psyched for.
- What kind of person? Lizard man with a 2-chambered heart?
  
  Dude your mom with a two chambered heart
- What would this shit look like if it was still pumping...
  C'mon Cronenberg, get on it!

- Moooooom, NCD is leaking again!

Thought it was going to turn into Saddam there for a second.
- Missed opportunity
- Now you’ve called it
- That's step f.
- Maybe it's a part of Saddam? Heart, foreskin, who knows.
- It has

Why does it look like a foreskin?

Callback to our primordial tube-hearted fish origin

Make sure to unfold and wring out your heart after each breakup, to keep the creases from setting in too much.

Naaaaah let's not
- Origami ^origami ^{ᵒʳⁱᵍᵃᵐⁱ}

I wonder if a heart could still beat/function when it's unrolled in this way 🤔
- No. It needs to squeeze against itself to move blood to and from chambers.
  
  Could it not just sorta flex the tube? Like couldn't one part of the tube pull on or press off of the next?
- I was wondering something similar. Maybe this is an innovative approach to heart surgery.
  
  Yes, in the way that Mengele was innovative in the medical field.
  
  ... I see I'm not the only person with intrusive thoughts.
- It depends on how fresh ~~the kill~~ it is.

That's not the shape of my heart 🎶

Thanks, I hate it

Look up embryological development of the heart to see why
- That's even better. Two blood vessels that fuse and twist.
  
  Why did they name the left and right atrium backwards? That seems unnecessarily confusing.

For a total eclipse of the heart you would need a moon shaped like a big hambone.

Interesting, but this isn't an entire heart, is it? Only half? Or isn't a human heart? Human hearts have separate left and right pairs of chambers which pump oxygenated and de-oxygenated blood separately. Or am I mistaken?
- Isn't that why there are 2 loops at the bottom? One for the left and one for the right?
- I just assumed that they dissected through the heart to unfold it. In humans the heart is ‘compact’ and there’s no real way to unfold it without cutting through cardiac muscle but, the heart embryologically develops from a tube that folds over itself so you can theoretically ‘unfold’ it.
- Considering this picture of a whole heart you are probably correct
- There are two "halves" but they're nowhere near symmetric. The two parts nested inside one another in (a) are the "halves".

I just learned about this last night. Are we a hive mind?

🎵 And no one's gonna bend or break me 🎵
- That's Faith of the Heart.
  Shape of my Heart is a different, but equally bangin', song.
  🎵I know that diamonds mean money for this art, but that's not the shape of my heart🎵

Not that I want to unroll it, but why did it "roll" up in the first place? It seems so tightly wound compared to, like, the intestines or something. Just curious.
- To save space
  
  And maybe to share muscle power between different phases of the stroke. Two muscles that evolved to pump different chambers could both work on the same chamber when they’re folded over one another. Allow them to transfer force between the layers.

It starts out as a tube and folds into its final shape, but I'm suprised it can be reversed, holy crap...

Mayas knowing it since centuries, due their life experiments.

This tore my heart apart.
