Death is the cessation of all biological functions that sustain a living organism. It marks the end of an individual's life and can occur due to various causes, such as old age, disease, injury, or environmental factors. From a biological perspective, death involves the failure of essential systems, including the circulatory, respiratory, and neurological systems. When these systems stop functioning, the body can no longer maintain homeostasis, leading to organ failure and ultimately, the irreversible cessation of life.
