We’ve already discussed the likelihood that zombie blood flows in order for many vital body functions to continue working (see: Zombie Ocular Hydration Theory). Now ZRS contributor, Zack Miller, observes that in the absence of a beating heart, the brain must power zombie blood. His theory is that this is done through a process of magnetic attraction and repulsion.
Citing a 2003 University of Virginia study, Miller notes that human blood can be propelled through the vascular system by magnets.
“Human red blood cells house a substance called hemoglobin, which gives blood its particular color. A hemoglobin molecule contains enough iron to make reds cells paramagnetic, and therefore subject to the effects of magnetic fields.”
In fact, many cultures have used magnetic theropy to treat illness and encourage blood flow to specific parts of the body for centuries.
Because it’s clear that the undead possess a fundamentally different physiology than your typical human corpse, Miller goes on to suggest that changes occuring in the electrical pulses of the brain as it passes from human to zombie may also create the necessary conditions for magnetization.
