Decomposition and Post-Mortem Changes

The video explains the stages of body decomposition after death, starting from the cessation of the heartbeat to the eventual breakdown of bones. It covers changes in body color, temperature, stiffness, and the release of gases and odors. The process involves various stages, including rigor mortis, algor mortis, and putrification, attracting bacteria, fungi, and animals. The video concludes with the final decomposition of bones into dust.

What is the first stage that occurs immediately after the heart stops beating?

• The body changes color

• The brain dies

• Rigor mortis sets in

• The body releases waste

What causes the body to change color after death?

• Insects arrive

• The body loses heat

• Blood settles in the lowest parts

• Muscles contract

What is the term for the body's loss of warmth after death?

• Putrefaction

• Livor mortis

• Algor mortis

Why might a deceased body appear to move?

• Insects are present

• Muscles contract as they die

• The body is decomposing

• The skin is loosening

What happens when the brain no longer regulates involuntary functions?

• The body loses heat

• The body changes color

• The skin loosens

• The sphincter opens and waste exits

What attracts insects and animals to a decomposing body?

• The skin's loosening

• The body's warmth

• The release of putrid odors

• The body's movement

What causes the eyes to bulge and the tongue to swell during decomposition?

• Insect activity

• Muscle contractions

• Gas production in the intestines

• Skin loosening

What is the final stage of decomposition where the bones break down?
