- atrophy
- a decrease in the size of a tissue or organ caused by a decreased number of cells or reduction in the size of the individual cells
- dehiscence
- the separation and disruption of previously joined wound edges
- dysplasia
- an abnormal differentiation of dividing cells resulting in changes in the size, shape, and appearance of the cells
- evisceration
- the separation and disruption of previously joined wound edges to the extent that intestinal contents protrude through the wound
- fibroblasts
- immature connective tissue cells that migrate into a healing site and secrete collagen
- hyperplasia

- hypertrophic scar
- an inappropriately large, red, raised, and hard scar that occurs when the body produces excess collagen tissue
- hypertrophy
- an increase in the size of existing cells without cell division
- inflammatory response
- a sequential reaction to cell injury that neutralizes and dilutes the inflammatory agent, removes necrotic materials, and establishes an environment suitable for healing and repair
- lethal injury
- an irreversible process that causes cell death
- metaplasia
- the reversible transformation of one cell type into another
- necrosis
- the death of cells within a living organism
- pressure ulcer
- a localized area (usually over a bony prominence) of tissue necrosis caused by unrelieved pressure that occludes blood flow to the tissues

- repair
- healing as a result of lost cells being replaced by connective tissue
