Understanding the Decomposition Process

The video explores the process of decomposition after death, starting with the cessation of bodily functions and progressing through stages like primary and secondary placidity, rigor mortis, and liver mortis. It discusses how environmental factors influence decomposition rates and details the cellular and microbial activities that occur. The video concludes with a reminder of the importance of exercise for longevity.

What is the first stage of decomposition called?

• Secondary Placidity

• Rigor Mortis

• Liver Mortis

• Primary Placidity

During which stage does the body start to lose heat?

• Primary Placidity

• Death Chill

• Liver Mortis

• Rigor Mortis

What is the visible sign of liver mortis?

• Body stiffening

• Skin turning purplish

• Muscle relaxation

• Temperature drop

How long does rigor mortis typically last?

• 1 to 2 days

• 20 to 84 hours

• 3 to 6 hours

• 5 to 10 hours

What happens during secondary placidity?

• Body stiffens

• Muscles relax again

• Body loses heat

• Skin turns purplish

Which environment causes the fastest decomposition?

• Buried in mud

• Frozen

• Exposed to air

• Immersed in water

What internal change occurs as the body decomposes?

• Build-up of toxic gases

• Decrease in carbon dioxide

• Increase in oxygen

• Increase in temperature

What attracts microorganisms to the decomposing body?

• Low pH

• Lack of oxygen

• Presence of nutrients

• High temperature

What is released by microorganisms during decomposition?

• Proteins

• Oxygen

• Water

• Chemicals and gases

What is one of the leading causes of preventable deaths worldwide?

• Lack of physical exercise

• Excessive sleep

• Overeating

• High stress
