This presentation is for those who want to understand the basics of reversible cell injury.

Difference between reversible and irreversible cell injury,Mechanism of cell ...Rukhshanda Ramzaan
Cell Injury: Any change resulting in loss of the ability to maintain the normal or adapted homeostatic state.
Agents that cause cell injury
• Hypoxia / Ischemia (loss of blood supply)
• Microbial
• Parasitic
• Chemical
• Physical
• Trauma
• Genetic
• Nutritious
• Environmental
Types of Cell injury
Reversible Cell Injury
Pathologic changes that can be reversed in mild cellular injury when the stimulus is removed. Cell injury is reversible only up to a certain point otherwise it will be irreversible.
Changes in reversible cell injury
Cellular Swelling: Due to accumulation of intracellular water and endoplasmic reticulum & mitochondria.
Clumping of chromatin.
Irreversible Cell injury
Pathologic changes that are permanent and cause cell death, they cannot be reversed to normal state.
Changes in irreversible cell injury
Irreversible injury is marked by severe mitochondrial vacuolization, extensive damage to plasma membranes, detachment of ribosomes from the granular endoplasmic reticulum (ER). Injury to lysosomal bodies leads to leakage of lysosomal enzymes into the cytoplasm and condensation, fragmentation and lysis of nuclei.
This is a presentation on the topic of Adaptations, Cell injury and cell death, prepared by Dr Ashish Jawarkar, he is MD in pathology and a teacher at Parul institute of Medical sciences and research Vadodara.
