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!

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...

for the zombies to do most zombie things, they would have to be alive. Which contradicts that one zombie thing where they're supposed to be dead.

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.

Yup, seems like every zombie movie and show has slightly different "rules" to fit the plot's premise.
