What happens at death?

 Hello friends, I'm new to Steemit, my name is Jose, I'm 22 years old and this is my first post I hope you like and learn them. Follow me @ droid8 

 Death is as natural as  birth but held less, the moment of death the brain has an increased  activity as its last oxygen is exhausted and darkness arrives. The  hormones that regulate the functions of the body are no longer secreted  by the brain and although some physical functions are maintained for a  few minutes eventually all human functions are maintained and the  PostMortem process begins. First in death all the  muscles are relaxed you need to burn oxygen so that the energy stays  tense, without oxygen there is no tension. 

 This includes the  sphincters of the body reason why death can cause defecation and  incontinence, just because the body is medically dead does not mean that  everything is. Some cells continue to burn the remaining energy that  contributes to what happens after dying. Not to mention the hundred trillion bacteria that live in our gut, in the skin and elsewhere. They  have been with us all our lives there is no reason to stop now, on  average the human body loses 0.83ºC / h, until reaching the ambient  temperature, without the heart beat the blood and fluids you begin the  process of lividity, succumbing gravity and Grouping in the lowest points of the body. 

 In people with  fair skin the blood grouping is visible outside the body with a dark  blue or purple color, and after a few hours it coagulates so forensics  know if a lifeless body has moved, according to a study 63% of People completely close their eyes when they die. 

 The decomposition begins,  the cells are dead and begin to break because of necrosis, without  circulation the body can not clean dead cells, as carbon dioxide builds  up and the pH of tissues increase the cells weaken And rupture the membranes releasing the inner fluid that causes damage and change the color of the surrounding tissue. 

 On the second and third  day putrefaction begins, oxygen is depleted by microorganisms in  respiratory systems and intestinal gas and these begin to spread to  other sections of the body. The enzymes in the pancreas begin to target themselves and the intestinal bacteria like it too so that the greenish abdomen. 

 This is when the smell is  absurdly terrible, two chemicals putrescine and cadaverine arise during  this interaction and eventually go to the blood vessels, necrosis and  bacteria work change the color from green to purple and then to black. The  smell will cause more insects to reach the body, worms and bacteria  will produce holes in the body which will occur in the first week and  release more odors. 

 These worms can consume  60% of the body in just one week, after the organs and tissues begin to  dry this stage takes a year or more depends on the temperature. Once  the fluids are mostly dry starts the post-decomposition soft tissues  and the organs are dried and consumed but the bones and cartilage are  still there, this is when a variety of beetles and flies remain to eat  what remains, in the years Later the plants and animals will eat the skeleton and you will become dust. 

 PS: Of course in  modern life we never arrive more than the first few days, embalming  helps to replace these processes, everything I mention happens to leave a  body lying around. 

 I hope this information has been useful and instructive, see you soon!
