This tore my heart apart.
Thanks, I hate it
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.
For a total eclipse of the heart you would need a moon shaped like a big hambone.

Moooooom, NCD is leaking again!
Look up embryological development of the heart to see why
It’s even better. Two blood vessels that fuse and twist.
Why did they name the left and right atrium backwards? That seems unnecessarily confusing.
It’s only backwards because you’re looking at it from the outside from the front. When it’s in you, the left is on your left.
I just realized I’m stupid, thank you
A true inflection point no doubt
welcome to the club bro
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?
There are two “halves” but they’re nowhere near symmetric. The two parts nested inside one another in (a) are the “halves”.
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 embryological 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
Isn’t that why there are 2 loops at the bottom? One for the left and one for the right?
That’s not the shape of my heart 🎶
I just learned about this last night. Are we a hive mind?
Thought it was going to turn into Saddam there for a second.
It has
Maybe it’s a part of Saddam? Heart, foreskin, who knows.
Now you’ve called it
That’s step f.
Missed opportunity
🎵 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🎵
Make sure to unfold and wring out your heart after each breakup, to keep the creases from setting in too much.
