Cell Damage and Injury Quiz

Cell Damage: Causes and Effects

• Cell damage refers to the changes that occur in a cell due to external and internal environmental factors.
• It can be caused by physical, chemical, infectious, biological, nutritional, or immunological factors.
• Cell damage can be reversible or irreversible depending on the extent of injury.
• The cellular response to injury may be adaptive, and the cell tries to restore homeostasis.
• Cell death occurs when the severity of the injury exceeds the cell's ability to repair itself.
• The length of exposure to a harmful stimulus and the severity of damage determine cell death.
• Cell death can occur through necrosis, which is the death of cells in a localized area.
• Alternatively, apoptosis, a programmed cell death, can also occur.
• Physical agents like heat or radiation can damage cells by coagulating their contents.
• Impaired nutrient supply, such as lack of oxygen or glucose, can deprive cells of essential materials needed for survival.
• Impaired production of adenosine triphosphate (ATP), the energy currency of cells, can also lead to cell damage.
• Understanding the causes and effects of cell damage is crucial for developing strategies to prevent or treat various diseases.
