People die when they are killed because death results from the cessation of vital functions necessary to sustain life. When a person is killed, their body undergoes irreversible loss of critical functions such as heartbeat, breathing, or brain activity, leading to death.
Death and Its Cause
Death is the irreversible cessation of all biological functions that sustain a living organism. In humans, death can occur due to various causes, including diseases, accidents, injuries, and intentional harm. When a person is killed, it means that some form of trauma or lethal action has caused the body to stop functioning, leading to death.
Biological Basis of Killing Leading to Death
Specifically, killing often involves mechanisms that abruptly stop the heart from pumping blood, the lungs from breathing, or the brain from functioning. These mechanisms deprive the body tissues, especially vital organs like the brain and heart, of oxygen and nutrients, resulting in irreversible damage and eventual death.
Medical and Forensic Perspectives
For instance, forensic studies show that deaths mentioned as "beaten to death" are due to internal injuries such as intracranial hemorrhage, blood aspiration, or hypovolemic shock, which prevent the body's vital systems from surviving, thus leading to death.
In summary, the phrase "people die when they are killed" reflects the biological truth that death follows the cessation of essential life-sustaining processes caused by lethal injury or trauma.
