What are some changes that occur in a body after death?

After death, the body undergoes several physiological changes that can be observed and studied. These changes include changes in temperature, clouding of the corneas, and livor mortis.

Changes in temperature, often referred to as algor mortis, occur as the body cools down to match the ambient temperature. This process begins shortly after death and can provide estimations of the time elapsed since death.

Clouding of the corneas typically happens within a few hours after death due to a loss of moisture and the cessation of normal physiological functions, leading to changes in the appearance of the eyes.

Livor mortis, or postmortem hypostasis, is the pooling of blood in the lower parts of the body due to gravity, which begins shortly after death and can be a critical indicator of the position of the body at the time of death.

The correct answer encompasses all of these changes, demonstrating a comprehensive understanding of postmortem processes. Each of these phenomena provides valuable information in forensic science and can assist in determining the circumstances surrounding an individual's death.
