People who suffer from immune system deficiencies struggle with all sorts of problems.The human immune system keeps us alive by laying waste to infection, bacteria, and diseases.Because zombies do not have an immune system, their bodies would be destroyed by bacteria and fungi.Viruses, fungi, bacteria and other microscopic pathogens have always posed a threat to zombies.

#3 Time Heals All Wounds, But Not for Zombies20        Before the advent of antibiotic creams and pills, simple scrapes and cuts were a treacherous endeavor even for healthy-as-a-horse humans. Cuts allow dirt and germs to get a little wiggle room and make their way into your body, but with proper hygiene, including wound rinsing and hand washing, most people eventually recovered from these kinds of injuries.21        While humans have tissues that can regenerate and heal themselves, zombies do not. Their wounds, no matter how mild or severe, are permanent. Imagine, if you will, a paper cut that not only doesn't heal but actually becomes wider and deeper by the day. As the flesh continues to divide, more bone is visible, and eventually, the last drooping flaps of flesh fall to the ground. A small scrape would blister into peels of skin that sag and slide right off of a zombie's body. Skin charred by burns would curdle into a goopy, grimy mess. *1 pointBecause zombies wounds cannot heal, their injuries would only get worse and worse until their body began to fall apart.Humans have tissues that can regenerate and heal themselves, zombies do not.Cuts and open wounds allow dirt and germs to make their way into your body, causing damage.Zombies wounds are permanent.

#7 Metabolic Meltdowns8          We humans eat food so that we can convert chemical energy into the activities that keep us alive, from breathing to reproduction. It's our metabolism that maintains these processes. Metabolism is an overarching term encompassing all of the chemical reactions that happen within our bodies. The nutrients that humans consume begin to break down the moment we start chewing up a slice of pizza or quiche. Our stomachs take over from there, converting those nutrients into calories that we need to stay alive.9          In theory, zombies consume brains because they, too, require sustenance that perpetuates their ability to function. There's just one problem — zombies aren't actually alive. As members of the undead society, they lack metabolic capabilities of any kind.10        Even if they could magically summon the energy to chomp on some tasty brains, their stomachs (if they even have stomachs) couldn't provide a chemical pathway for nutrients to convert to energy, leaving the undead rather inanimate and, well, lifeless.*1 pointEnergy from food helps keep us alive by providing energy and nutrients.Zombies would not have the metabolic functions necessary to get energy from food, which would leave them limp and lifeless.Metabolism is an overarching term encompassing all of the chemical reactions that happen within our bodies.Humans are different from zombies because zombies eat brains for energy, while humans use food for nutrients.

#2 Zombies Probably Can't Poop22        Your stomach is a muscular bag that has a capacity of roughly 30 ounces (0.89 liters) of liquid and solid matter. People who eat large meals regularly may stretch that capacity to some degree. And those who go on steep diets may actually shrink their stomachs.23        Zombies are the competitive eaters of the monster world, inclined to stuff themselves at each and every brain buffet they can find Because zombies aren't known for their fully functioning bodies, there are some problems with this style of consumption.24        Zombies are likely to have gaps in their digestive system somewhere between their mouths and anuses meaning there's a good chance that the brains they eat will just hit a dead end (pun intended) where the esophagus hits the stomach.25        As the zombie dines on more and more brains, the undigested flesh would just pile up and ferment, creating bubbling gases and eventually bursting through the walls of the zombie's stomach.*1 pointZombies have no way to break down or poop out what they eat so eventually their stomach/intestines would explode.The undigested flesh in zombies' stomachs would just pile up and ferment, creating bubbling gases.Zombies are the competitive eaters of the monster world, and will stuff themselves as much as possible.Zombies can't poop.

If zombies behave exactly like conscious beings, then it follows that functionalism is false. Group of answer choicesTrueFalse

True/False: The immune system is the only system that protects the body from diseases
