What are the factors of cell injury?

Cell injury can be caused by various factors, including physical agents (like trauma or temperature extremes), chemical agents (such as toxins or drugs), biological agents (like bacteria and viruses), and nutritional imbalances (deficiencies or excesses). Additionally, hypoxia (lack of oxygen) and immune responses can contribute to cellular damage. The severity and duration of the injurious stimuli, as well as the cell type and its adaptive capabilities, play crucial roles in the extent of injury. Ultimately, these factors can lead to reversible or irreversible cell damage, depending on the circumstances.
