How would apoptosis work for animals?

Apoptosis, or programmed cell death, is a crucial process in animals that helps maintain tissue homeostasis, eliminate damaged or potentially harmful cells, and shape developing organs. It involves a series of tightly regulated biochemical events, including cell shrinkage, chromatin condensation, and fragmentation of DNA, followed by the engulfment of the dying cell by phagocytes. This process is essential for normal development, immune function, and preventing cancer by removing cells that exhibit abnormal growth. Ultimately, apoptosis ensures the health and stability of the organism by regulating cell numbers and maintaining cellular integrity.
