The process of programmed cell death is known as apoptosis. This is a highly regulated and controlled mechanism through which cells undergo death in response to various signals, such as developmental cues or cellular damage. Apoptosis plays a crucial role in maintaining homeostasis within the body, as it allows for the elimination of damaged or unwanted cells without causing inflammation or harm to the surrounding tissues.

In contrast, necrosis refers to uncontrolled cell death often resulting from injury, infection, or lack of blood supply, which typically leads to inflammation and can have deleterious effects on the surrounding cells and tissue. Autophagy is a cellular degradation process where cells recycle their components, which is essential for cellular maintenance and survival, but is not a form of cell death. Mitotic death refers to the death of cells during mitosis, typically resulting from errors during cell division, but again does not represent the programmed and orderly process that characterizes apoptosis. Thus, apoptosis is distinctly defined by its role in normal physiological processes, distinguishing it from other forms of cell death.
