  • Yes, partially decayed zombies are gross, but what REALLY happens to THIS BEAUTIFUL

  • SPECIMEN OF HUMAN MEAT after it dies? Let's get grossly detailed!!!

  • Death is as natural as birth, but celebrated a lot less. At the moment of death, the brain

  • has a surge of activity as its last oxygen is depleted, and it then goes dark. Hormones

  • which regulate body functions stop being secreted by the brain, and though some physical functions

  • continue for a few minutes, eventually all human functions stop and the post-death process

  • begins.

  • Firstly, at death, all muscles relax. It takes burning oxygen for energy to keep you tense,

  • no O2, no tension. This includes the body's sphincters, which is why death often cause

  • defecation and incontinence. Now, just because the body is medically DEAD, doesn't mean everything

  • is. Some cells continue burning remaining energy, which contributes to what happens

  • after we die. Not to mention the 100 trillion bacteria living in our intestines, on our

  • skin and elsewhere. They've been with us our whole livesno reason to stop now.

  • Algor mortis, or the death chill, begins immediately at death. On average, a human body loses 1.5

  • degrees (.83 C) an hour until it reaches room temperature. Without a heartbeat, blood and

  • fluids begin the lividity process, succumbing to gravity and pooling at the lowest points

  • in the body. In light-skinned people, pooling blood is visible outside the body as a dark

  • purplish-blue, and after two hours it clots! This is how forensic specialists can tell

  • if a body has been moved.

  • Within three to six hours, rigor mortis sets in, tensing the muscles again. After death,

  • calcium floods the muscles, and bonds with proteins that control muscle contraction.

  • This uncontrolled bonding causes muscles to tense for 24-to-48 hours. The eyes will cloud

  • over during this time, especially if left open. And once rigor sets in, they're stuck

  • that way for a while, so that whole closing eye thing in movies? It's possible as long

  • as you get to them quickly. Though you might not have to, because according to a study

  • in the Indian Journal of Palliative Care, 63 percent of people fully closed their eyes

  • at death! Which seems like a lot to me...

  • OKAY. SO. You're dead, and decomposition is starting. Your cells are dead, and are begining

  • to break down. In this case, cell death happens because of necrosis. It's messy, and without

  • circulation, the body can't come clean up the dead cell. As carbon dioxide builds up

  • and the pH of the tissues rise, the cells weaken and eventually their membranes break,

  • releasing their insides into the surrounding tissue. Enzymes in that fluid cause damage,

  • blistering and color changes, this continues for a while...

  • By the second or third day putrefaction sets in. Oxygen is been depleted by the natural

  • microorganisms in our respiratory and gastrointestinal systems, and they've begun to spread into

  • other sections of the body. For example: enzymes in the pancreas cause it to digest itself,

  • and the gut bacteria LOVE that, so they eat it too -- which turns the abdomen a greenish

  • color. Gas begins to build up, forcing any non-digestibles like feces; out of the body.

  • This is when the smell is justbeyond horrible. I've smelled it, you don't want to. Two organic

  • amine chemicals: putrescine and cadaverine are created during this interaction, and eventually

  • it makes its way into the blood vessels. Picture a post-apocalyptic highwayusing that,

  • they get to the rest of the body and ooze out causing a horrid rotting smell. Eventually,

  • necrosis and the work of bacteria changes the greenishness, to purple, and then BLACK.

  • The smell causes more insects to come lay eggs and invade the body. A single blowfly

  • can lay 300 eggs which will hatch in a single day. Their larvae will hatch and eat tissues

  • nearby for a week as a maggot before transforming into a fly itself! Over the next week, maggots

  • and bacteria pop holes in the body, releasing the gas (and the smell) even more. These maggots

  • can consume 60-percent of a body in just a week! But there's still a lot to go, this

  • was just the first WEEK. Next, butyric fermentation starts and the organs and tissues begin to

  • dry out and wax over, sort of like a mummy! The tissues are being slowly digested by MORE

  • bacteria, insects, protozoa, and fungi. This stage takes a long time, maybe as much as

  • a year or more in moderate temperatures.

  • Once the fluids are mostly dry, post-decay starts. The soft tissues and organs are dried

  • up and consumed, but bones, hair, cartilage and sticky byproducts of the earlier stages

  • are still around. This is when a variety of beetles and flies move in each species looking

  • to eat away at part of what's left. Over the subsequent years, plants and animals will

  • eat away the skeleton and eventuallydust to dust. Gone forever.

  • Of course, in modern life, we usually never get past the first few days. Embalming helps

  • delay much of these processes, as does cooling the body! This is if you left a human laying

  • around, like an old pizza. Sure, we die, but all these things live on thanks to our gross

  • wet corpses! It's inevitable, and fascinating. I could do five more episodes on this stuff!

  • Let us know what you think about this down belownot likeburied or whatever

  • like in the comments.
