Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

How can you have a heartbeat but no pulse? Aren't those the same thing? ๐คจ
Heart can continue to beat but if there's nothing to pump through the blood vessels, you won't feel a pulse.
Electrical current firing in the heart can be picked up by EKG, but if there is no blood left in the tube you have no blood pressure.
Wouldn't it run out of oxygen?
Eventually, but it's a muscle. Salt applied to freshly butchered meat will spasm because it's still muscles with sugars left to burn.
Same thing like if someone gets decapitated. The heart might still pump for a while and shoot blood out everywhere. Doesn't mean the person of still alive.
Have you witnessed both these things?
Doesnt mean they're dead. Could still have brain function a minute or SO after decapitation.
Yes.
If you cut out the heart it will beat for quite some time after death
If you culture cardiac muscle cells, they start beating.
Depends on how neatly you cut it. If you just hack and slash, it doesn't last very long at all. But, as with everything, the more you practice, the better you ...
Oh, wait.
Uh, NVM.
"Things only my ex would know"
I am doubtful of that but I haven't ripped enough hearts out of people to know for sure.
The quite some time seems hard to believe but the idea that heart transplants occur must mean that there must be some wiggle room I guess.
