Tired of the fake hearts and the sugary candy? Want to talk about the bleeding human heart instead?
Gladly!
Perhaps the most fascinating thing about the heart is that it keeps beating on its own, without us ever having to conciously think about it. This is because the heart actually has ganglia surrounding it, sometimes called the heart-brain. That means that basically, the heart sends more information to the brain than the brain does to the heart, and the heart doesn't merely keep beating because of signals from the brain, but also because of the very nervous system it is tied to.
