    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.

          Doesnt mean they’re dead. Could still have brain function a minute or SO after decapitation.

            Seconds, maybe. Once the brain loses blood pressure, most functions outside the stem go offline.

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.

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.
