Cellular injury happens when a cell is stressed too much and can no longer adapt. Here are some key ways this can occur:
Low Oxygen and Blood Flow: When there isn't enough oxygen, cells can't make energy. This can lead to problems. For example, heart cells can get hurt during a heart attack because they don't get enough oxygen.
Chemical Damage: Harmful substances can interfere with how cells work. For instance, taking too much acetaminophen can harm liver cells.
Infections: Bacteria and viruses can invade and destroy cells. A good example is HIV, which attacks immune cells in our body.
Body's Defense System: Sometimes, the body's own defenses can be too strong and cause damage. This happens in autoimmune diseases, where the body attacks its own cells.
By understanding these causes, doctors can better diagnose and treat cellular injuries.
