Corrected entry: Many times throughout this show, some zombies have been depicted as being burnt to a crisp with barely anything left, but still moving, or having been crushed or have their chests completely destroyed. Some even being that the head is the only thing left. Yet these zombies still growl, hiss and grunt. This is not possible without lungs attached to flow air through the throat and mouth.

Correction: This is typical in most zombie-lore and shouldn't be considered a mistake given every other aspect of what zombies are shown to do that would otherwise be impossible in real life.
