Stages of Human Decomposition

The video tutorial explains the stages of human decomposition using a piglet model due to its similarity in fat distribution and other factors. It covers five stages: fresh, bloat, active decay, advanced decay, and dry decay. Each stage is characterized by specific processes and changes in the body, such as rigor mortis, gas production, mass loss, and mold growth. Understanding these stages helps determine the time since death.

Why are piglets used as models for human decomposition in studies?

• They decompose faster than humans.

• Their fat distribution and hair covering are similar to humans.

• They have a similar bone structure.

• They are easier to obtain than human bodies.

What is rigor mortis?

• The breakdown of cells.

• The pooling of blood in the body.

• The cooling of the body after death.

• The stiffening of muscles after death.

Which process is characterized by the cooling of the body after death?

• Rigor mortis

• Algor mortis

• Livor mortis

• Autolysis

What causes the swelling of the body during the bloat stage?

• Drying of the body

• Loss of body fluids

• Gas production by dying cells

• Insect activity

What skin change occurs during the bloat stage?

• The skin develops mold.

• The skin becomes pale and cold.

• The skin turns a greenish tint.

• The skin becomes dry and cracked.

During which stage does the body start to lose mass significantly?

• Bloat stage

• Fresh stage

• Dry decay stage

• Active decay stage

What happens to the body fluids during the active decay stage?

• They solidify inside the body.

• They evaporate completely.

• They begin to leak from the body.

• They are absorbed by the skin.

What is a key characteristic of the advanced decay stage?

• Increase in insect activity

• Body starts to dry out and ferment

• Body becomes bloated

• Complete absence of moisture

What happens to insect activity during the advanced decay stage?

• It increases significantly.

• It decreases.

• It stops completely.

• It remains constant.

What remains of the body during the dry decay stage?

• Bones and mold

• Bones and some fluids

• Bones and dry skin

• Only bones
