What is the difference between reversible and irreversible cell injury? 4. How does apoptosis differ from necrosis? Be sure to include in your response the morphologic differences. 5. Can cell injury caused by hypoxia or anoxia be reversed or repaired by providing the cells with adequate oxygen? 6. Use a time-line/flow-chart to illustrate how wounds heal by first intention. 7. Describe how the process of wound healing differs by first intention from those that heal by second intention. What is inflammation and compare and contrast between acute and chronic inflammation? 8.

2)It is caused by infection, injury or trauma, toxins which resulted in unregulated cells and its death
3)Reversible cell injury can be brought back to normalcy after treatment where as irreversible cell damage cannot be brought to normalcy after damage eg., cancer cells.
4)apoptosis means a programmed cell death, necrosis means death of cells and cessation of blood supply numbness and the area turns into green ,black color and needs surgical intervention to treat it
