Matters of the Heart
So it’s been a little while since I’ve written something here. And it’s not because I haven’t still been learning new things. I am. All the time. Every day.
I’ve just been busy, okay? Ha.
Anyway! I’m back today to share something I recently learned about my heart. Well, not just my heart. Yours, too!
Okay, so we all know what the human heart looks like, right?
But did you know that it didn’t always look like this? In your body, I mean. Before you grew a mini version of this inside your mother’s womb when you were nothing but a teeny-tiny embryo-type thingy, you had something that looked more similar to the heart of a goldfish—like a little tube. Then after some more growing, it transformed into a two-chambered heart, like a frog’s. After that, the third chamber developed, looking a little bit like a snake’s heart. Which is kind of badass, I think. (Just me? Cool, cool.)
Eventually, that final fourth chamber developed, started beating, pumping blood and oxygen, and all that good life-sustaining stuff.
I gather this may be basic biology for some (or even most of you). But I had actually never had it explained to me in this way before—and I like it.
Speaking of animals and hearts, did you guys know that the zebrafish can fully regenerate their heart muscle? I feel like that could come in handy. Broken heart? No problemo. Just grow a new one!
Or something like that…
