Each type of cell has its own life span, and when a human dies it may take hours or day before all the cells in the body die." Red blood cells live for about four months, while white blood cells live on average more than a year. Skin cells live about two or three weeks.
A cell can die in many ways - through infection, poisoning, overheating or lack of oxygen. An uncontrolled death is messy: the cell swells up, and its contents leak away. This may damage surrounding cells.
Mitosis takes place in four stages: prophase sometimes divided into early prophase and prometaphase metaphase, anaphase, and telophase.
The length of a cell's life can vary. For example, white blood cells live for about thirteen days, cells in the top layer of your skin live about 30 days, red blood cells live for about 120 days, and liver cells live about 18 months.
