Algor mortis is one of three stages a body goes through after death that helps medical examiners determine time of death. This lesson. After the death of a person, the body undergoes certain changes in an orderly manner, namely pallor mortis, algor mortis, rigor mortis and livor mortis. Algor mortis cools down at In human, it usually appear in 2 hours after the death . The stiffness will begin from smaller muscles to larger.
