1.The last bit of oxygen in your body is used up, and brain activity surges briefly1 as neurons stop working and the brain stops secreting2 hormones3 that regulate body function. 
The last of the energy stores (ATP) is used up and the sphincter relaxes, causing the body to release urine and excrement4
2. Between 15 and 25 minutes after death, the lack of blood flow to capillaries5 causes the skin to go pale. 
The heart is no longer beating, so blood is not being propelled around the body. 
As a result, the blood pools in the lower parts of the body. 
3. After 12 hours, the skin will have reached maximum discoloration (or a reddish purple colour). 
Calcium6 leaks into muscle cells, binding7 to proteins which are in charge of muscle contraction8
The stiffness referred to as rigor10 mortis sets in three to six hours after death, and lasts for between 24 and 48 hours. 
4. Dead cells and carbon dioxide causes the PH level of your skin tissue to rise. 
This makes the cell membrane11 weak and it bursts, releasing proteins and enzymes12 which further break down the surrounding tissue. 
This is the process of decomposition13
5. Micro-organisms start to break down your body. 
Bacteria in the gastro-intestinal tract9 eats through the abdominal14 organs. 
This is called putrefaction15, and it causes the smell of death associated with a dead body. 
The breakdown16 of amino acids creates other strong-smelling acids which attract insects that lay eggs in the rotting tissue. 
The eggs hatch after 24 hours and the maggots eventually consume 60 percent of the body tissue over a number of weeks. 
6. Finally, the maggots create holes in the rotting flesh, which allow decomposition fluids and gases to escape. 
After a month and a half, beetles17 and fungi18 further consume the remains19
This is called dry decay which can take up to one year. 
Eventually, every part of the body will have been broken down and used.
