The document discusses cell injury and cell death. It explains that cells have a normal steady state of homeostasis but stress can force cells to adapt or become injured if the stress exceeds their capacity. Cell injury can be reversible or irreversible and leads to cell death if irreversible. Key systems vulnerable to injury are membranes, respiration, protein synthesis and the genetic apparatus. Causes of injury include hypoxia, toxins, infections and more. Reversible injury disrupts mitochondria while irreversible injury causes mitochondrial and lysosomal damage leading to cell death.
