7. Healing - the replacement of injured tissue with newly formed living tissue
8. Types of healing - resolution
-regeneration
-repair (scar tissue, fibrosis)
9. Resolution - damaged cells are reversibly injured and recover
10. Regeneration - damaged cells are replaced by the division of remaining viable cells of the
same type
-e.g., viral hepatitis
11. Repair - damaged cells are replaced by scar tissue

Depends on the cell type: hepatocyte): normally don't divide but can when needed Heal by
-Labile cell: regularly divide
(regenerate) throughout life repair: cardiac muscle cells have a very limited capacity to divide
-Permanent cell (e.g., neuron):
not capable of cell division
-Stable cell (e.g., Heal by resolution: ischemic or injured cells recover
