Heard in 3 episodes across 2 shows since Aug 2026

Cellular turnover is the biological process by which old, damaged, or dying cells are systematically replaced with newly generated ones to maintain tissue homeostasis and function. This continuous cycle of cell death and regeneration occurs throughout the body, with rates varying significantly across different tissues, such as the rapid renewal of blood and gut epithelial cells compared to the slower turnover of bone and muscle cells.
