1. The muscles immediately relax

Death is generally perceived to be when your major organs go still. You stop breathing, your heart stops, and the blood stops being pumped around your body. Once this happens, your muscles will start to relax - which means, in most cases, you'll actually piss yourself when you die!2. Including your eyes

One other thing that relaxes you might not have considered is your eyelids. In some cultures, it was common to put coins or stones on the eyes after death, and scientists theorize that this might be to prevent the eyelids from staying open at death. By moving them down and placing a coin on them, you ensure that they stay shut once the muscles have relaxed.3. And your skin

Your skin also starts to relax and sag as you die - this happens because the blood isn't pumping around your body anymore, and gravity can exert itself on your still body. When this happens, your skin will sag around major bones, like your cheekbones, pelvis, and hip bones, making you look even gaunter.4. Then, self-digestion starts
Image Source: eonline.com
Self-digestion sounds like something that happens when you're alive, right? Well, it doesn't. Actually, this scientific process is when cells begin to be deprived of oxygen. As this happens, they become more and more toxic as there is no oxygen to prevent the creation of these toxins. Enzymes eat the cell membranes, and a chain reaction starts in the body.5. Your cells release lots of chemicals

At this point, your cells release a lot of chemicals and toxins through those destroyed membranes. Remember, this is happening only very shortly after your death - and suddenly, you're a chemically-ridden body! This self-digestion, or autolysis, is the first stage of decomposition and means you're really dead.6. Including your liver and brain
Image Source: atonomousfx.com
Your liver and brain also undergo this process. It happens at a faster rate in the liver because there are lots of toxins there already, while in the brain, the presence of water speeds it up. However, all organs in the body will start to break down because of enzymes and the high amount of toxins.7. But your heart may go on
Image Source: metro.co.uk
However, many scientists believe that the heart may continue to beat and even restart itself after death. In one study, 14% of studied dead patients experienced a stop-and-start of the heart after death, sometimes occurring 30 minutes after they had been declared dead.8. And you may produce electrical signals still
Image Source: cbc.ca
Your brain also doesn't die immediately. Before the process of cell breakdown begins, it continues to send electrical signals to the rest of the body - though they won't register them because the cells are dying. In fact, consciousness may still continue up to three minutes after your heart has stopped beating.9. Your brain may even be aware of death
Image Source: vulture.com
This weird quirk of the brain means that you may experience some awareness of death for a short period after you've died. If you're unconscious, of course, this probably won't happen, but in other cases, you may actually be aware that you've died. Lots of patients report near-death experiences when they get saved by doctors, so who's to say what really happens?10. Your brain will die from the top downwards
Image Source: brainfacts.org
However, at some point, those electrical signals will stop and your heart will stop for good because of the lack of oxygen getting to those cells. Your brain starts to die from the top downwards because the blood is pumped in from the bottom of the brain. When this happens, those cells will start to leak toxins just like the other organs.11. While your skin will change color slowly
Image Source: newsweek.com
It's an image that everyone knows from murder shows like CSI - that of a slightly blue-purple corpse. The human body starts to change colour immediately after death, and this happens because as the skin cells erupt, damaged blood vessels spill out. These settle in capillaries and small veins, giving the whole skin a blue twinge.12. Blood stops flowing
Image Source: csi.fandom.com
Typically, once the blood has stopped flowing and your skin has turned colour, it's the point of no return. Your cells are beginning to collapse, and the first stages of decomposition have occurred. At this point, you move into a really important stage of death.13. Resulting in livor mortis
Image Source: dalicesworldofscience.weebly.com
Livor mortis occurs when the blood starts to pool at the bottom of your body - usually in your back if you've died while lying down like in a hospital. When this happens, you may get some discoloration in the skin of your back, like bruises. In the world of embalmers, this is referred to as the "postmortem stain".14. Your body temperature will drop
Image Source: insider.com
You probably also know that once you start to die, your body temperature will drop. Dead bodies are always cold, right? Well, this process starts immediately after death, when your body will start to cool by 1.5 F every hour. It won't necessarily get colder than the outside air, though - the body will just adjust to its environment.15. And rigor mortis sets in
Image Source: biologydictionary.com
Rigor mortis occurs after livor mortis - it's when we really become a dead body. While the muscles began the dying process by relaxing, now they start to get stiff as the proteins in the muscles become locked in place. It's the classic image of a stiff, hard-to-move dead body.16. Your body stiffens from the top down
Image Source: Everplans
Rigor mortis doesn't just happen across the body at the same time, though. The first things to go are the eyelids (remember the coin trick?), followed by the rest of the face, the jaw, and the neck. Then the stiffness begins to descend down the body.17. Ending with fingers and toes
Image Source: forensicfingerprint.in
Because your fingers and toes are at your extremities, these will be the last areas to experience rigor mortis, and actually reach peak stiffness (no laughter, please.) Once this happens, all your muscles will be completely locked into the place they were left at when you died (provided nobody's moved you recently after death!)18. This reaches a peak
Image Source: pathologyoutlines.com
Rigor mortis can take up to 12 hours to completely finish, but this will always depend on your size, physical condition, gender, and even the air temperature outside. If a child dies, they can most times not even experience rigor mortis completely because they are much smaller than an adult.19. Then, bacteria go wild
Image Source: distractify.com
At this point, your body is really a breeding ground for bacteria. If it sounds gross, it's because it is. When we die, our immune system stops working, which usually sorts out any weird cells and bacteria in the body. Without that protection there, bacteria are free to travel around the body.20. Starting in the gut
Image Source: wired.com
Bacteria usually start to spread from the gut first - near your stomach and intestines. This is because your stomach contains lots of live bacteria that, when you're alive, help to digest food and even help your brain and nervous system. First, the bacteria start to devour the intestines.21. They spread around the body
Image Source: time.com
After they've had a nice intestine meal, they move around the body. They travel through the digestive system to the liver, which they reach about 20 hours after death. Then they'll go to the other major organs of the body, including the heart and brain.22. A new death begins
Image Source: mirror.co.uk
At this point, you undergo the next stage of the process of dying - molecular death. This is when all the cells in your body start to die, devoured by enzymes and destroyed by toxins that are coursing through your body. You've reached the stage when your body starts to become unrecognisable as a body.23. Your skin may sag again
Image Source: self.com
After molecular death begins, you'll also undergo secondary flaccidity (no jokes please!). This is when skin begins to sag again after experiencing rigor mortis. This happens over a period of 1 to 3 days after death, when your body will really start to smell.24. Are your nails growing?
Image Source: paramountplus.com
Because your skin begins to sag and contract after rigor mortis, at this point, it can often appear as if dead bodies have longer hair and nails. However, this is just an illusion as the skin has got smaller and left the nails and hair as long as it was before death.25. The muscles relax again
Image Source: spectrumnews1.com
As the muscles relax, it's a surefire sign that your body is completely breaking down and becoming rotten. This happens in the opposite direction to rigor mortis, meaning your fingers and toes are the first thing to become soft again, and ending with your neck, jaw and face.26. Soft tissue breaks down
Image Source: npr.org
As soft tissues start to break down, putrefaction begins. Your body is starting to decay, including your skin and all your internal organs. When this happens, some of your tissue will even revert back into natural salts and liquids - leaving you as a gross pool of old body parts.27. Your body produces gases
Image Source: today.com
Your body also produces gases as it decays. These often gather in the stomach - a large whole in the center of your body - meaning dead bodies often look bloated. In some cases, the pressure of the gases in the body can even cause an explosion!28. And changes color once more
Image Source: thesun.co.uk
Your skin would have taken on a blue-purple tinge during the first stages of death, but once you start to decay properly, your skin will change color once again. In fact, you'll go the true color of a rotten corpse - a greenish/black color. This is because your cells produce sulfhaemoglobin.29. Blisters appear on the skin
Image Source: theguardian.com
As the gas appears in your body, it can even blister the skin with its force. These blisters will appear all over the body, while some areas of the skin may rupture entirely from the force of the gases and toxins inside the cells. Your body might even enlarge to twice its size!30. Then you're really dead and gone
Image Source: dailymail.co.uk
At this point - when your skin is literally falling off and your cells are being eaten from the inside - you're really dead. At this stage, you're probably going to smell pretty bad too, and not be a very nice sight to see. Maggots are also probably living in your body, too. Lovely stuff!
