Decomposition of Human Body
This ppt contains graphic images. I put pictures on slides that do not contain information so feel free to avert your eyes. Information is also graphic and can be disturbing
5 stages of decomposition
•Initial decay
•Putrefaction
•Black putrefaction
•Butyric fermentation
•Dry decay
Initial Decay
•0-3 days after death•Bacteria in digestive tract start eating
intestines, break through and begin feeding on surrounding organs
•Individual cells break down, releasing cell contents and enzymes into body
Putrefaction
•4-10 days after death•Body will be bloated from build-up of
gases in body•Gases released by bacteria living in
intestines•Skin blisters•Build-up of fluids from ruptured cells and
intestines•Skin begins slipping
Black Putrefaction
•10-20 days after death•Body begins to collapse and black
surfaces are exposed•Bloated body collapses and leaves a
flattened body•Large volume of body fluids drain from
body
Butyric Fermentation
•20-50 days•Remaining flesh on body is removed and
body dries out•Cheesy smell (caused by butyric acid)•Surface of body in contact with ground
may mold as body ferments
Dry decay
•50-365 days after death•Body is dry and continues to decay very
slowly because of lack of moisture•Mostly reduced to hair and bones•Eventually the hair will disappear
