What is apoptosis?

Apoptosis refers to programmed cell death, a vital process that allows the body to eliminate unnecessary or dysfunctional cells in a controlled manner, thereby maintaining healthy tissue. During apoptosis, cells undergo a series of carefully regulated steps that lead to their destruction without provoking an inflammatory response. This process is essential for various physiological functions, such as tissue development, immune function, and the elimination of damaged or potentially harmful cells, such as those that might lead to cancer.

The correct understanding of apoptosis emphasizes its role in homeostasis and tissue health, as it helps ensure that cell turnover is balanced and that only the appropriate cells remain active in a given tissue context.
