Are our hearts really heart shaped?

THIS

sums it up

also makes me chuckle

There are lots of theories

I dont know but the heart looks cool XP

No.

@TheOnlyException Nice! I like that one.

Be a bit gross to have a bloody pumping heart on a valetines card.Kind of loses the romance slightly.

Of course; do you think someone just made it up?

I don’t think it does… why don’t you tell me, here.

Yes.

Since it is a heart. What shape it is would be heart shaped.

It is close from some angles, but not really in three dimensions. @RandomMrdan‘s link shows it in nearly the right angle. The small portion of the right atrium that you can see on the left of the image forms one dome, and the pulmonary artery forms the other. If you rotate the image clockwise 45 degrees in your head, you will see that it is quite close.

That is the best you will get though, since the classic ‘heart shape’ is 2D, and a functional human heart is an extremely intricate 3D structure.

@MarcoNJ glad to hear it! :)

More importantly, are our livers really liver shaped?

… and our kidneys bean-shaped?

@CyanoticWasp don’t know about that, but my beans are kidney-shaped!

It is, but not as precise as the <3 symbol we’re used to seeing. Our heart is somewhat divided into two sides – maybe that was inspiration for the popular symbol.

I enjoy this question… But more or less
I’ve seen diagrams where the ventricles are jammed all the way to the left, by, like, six inches. I’ve also seen diagrams where the heart is more round…

I’m going to have to say you might have to see a real one to answer your question
