Apoptosis:

Explanation

Apoptosis, often referred to as programmed cell death, is a highly regulated process in which cells undergo self-destruction in a controlled manner. This mechanism plays a crucial role in various physiological processes, including development, tissue homeostasis, and the immune response. Apoptosis involves a series of biochemical events that lead to characteristic morphological changes in the cell, such as cell shrinkage, chromatin condensation, nuclear fragmentation, and the formation of apoptotic bodies. These apoptotic bodies are then engulfed and digested by neighboring cells or phagocytes, preventing the release of harmful cellular contents and maintaining tissue integrity. Dysregulation of apoptosis can contribute to various diseases, including cancer, autoimmune disorders, and neurodegenerative diseases.
