  Also, their blood must be coagulated. Should be dripping solid blood

  Well, they can walk, they can eat, their muscles obviously work despite them being dead, why not the heart ? >
  
  I always assumed the brain was what was moving the muscles and nerves. If the heart still worked would they still be dead? >
  
  It is reanimated though. Where else would the blood go? At some point it would leak out or just pool up at the lowest points of the body... >
  
  I think it would congeal since they're cold >
  
  This is the correct answer. Zombies should not bleed. >
  
  People also forget zombies digestive systems don't work either. So all that flesh they consume builds and builds they literally rip open and you have this disgusting creature just oozing rotten flesh. >
  
  Nah, the meat goes through their digestive system, just without being processed. >
  
  Do zombies poop? >
  
  Well, not exactly, since it isn't digested. But something does come out the other end. >
  
  Well, that's a bit of a conundrum! We guess the only explanation is that zombie blood must have some kind of magical properties, allowing it to defy all laws of physics and keep flowing even without a living heart. That's one mystery we may never be able to solve! >
  
  Yup, seems like every zombie movie and show has slightly different "rules" to fit the plot's premise. >
  
  zombies aren't always the same in all of fiction. some can run, some are slow, some are magical and others are fungi or bacteria, some have a variant that makes sense, and some have completely crazy and un-realistic variants, some fight plants, some are dumb and can't even move without a person near them >
  
  There's no way to make zombies work.
  They would dehydrate and dry up pretty rapidly. They would run out of energy, regardless of what's making them tick, also pretty rapidly.
  They couldn't possibly be strong, they'd be more like elderly cancer patients, doddering on for a few hours before collapsing in a heap, never to move again. >
  
  There are two ways to make zombies work. Magic and Space Magic(sci fi magic). With magic you have reanimated dead being powered and moved by that source of energy. With space magic you say the "Alien bacteria" attach to "conscious lifeforms" to form a connection to the psychic energy field and then just replace magic with psychic.
  But yeah, simple disease based Zs just don't work. >
  
  Disease based infected would work.
  They wouldn't be OG zombies because they weren't dead, but rabies variants would be plausible. >
  
  The walking dead tried to explain it.  It was a parasite that infects the brain stem so after the host dies the parasite controls the nervous system allowing the body to move. >
  
  I think Jenner left it at bacterial or viral infection. "Like Meningitis" he said. >
  
  also, since they are dead, they should be dead, whats your point? >
  
  Then their heart should be dead too. Where is the blood coming from? >
  
  my point is that the fact that theyre moving at all doesnt make sense, so why bother with the smaller details?
