1Somatic death - [blank_start]Disappearance of life from entire[blank_end] individual
Necrosis - [blank_start]Local death of tissues or cells within a[blank_end] living individual
Autolysis - [blank_start]Breakdown of cell and tissues caused by[blank_end] enzymes within the body
Putrefaction - [blank_start]Breakdown of cells and tissues by[blank_end] bacteria from the surrounding environment, or from within the body itself
Cellular Degeneration - Damage causes [blank_start]dysfunction of the sodium potassium pump[blank_end] resulting [blank_start]in build up of Na+ ions within the cell[blank_end], causing cell swelling
Hypoxia - [blank_start]Lack of oxygen[blank_end]
Systemic reactions - [blank_start]Enzymes released from the dying cells[blank_end] may be found in increased quantities in the serum
Local reactions - [blank_start]Necrotic tissue initiates a mild local[blank_end] inflammatory reaction

3Atrophy - [blank_start]An organ or tissue has reached normal[blank_end] size but then shrinks
Hypertrophy - increase in the size of a tissue or organ [blank_start]due to an increase in the size of the[blank_end] individual cells
Hypoplasia - [blank_start]Incomplete growth of an organ or tissue[blank_end]
Aplasia - [blank_start]Absence of a tissue[blank_end]
Atresia - [blank_start]Absence or closure of a luminal[blank_end] structure
Hyperplasia - [blank_start]Increase in the number of cells[blank_end] in a tissue or organ
Dysplasia - [blank_start]Abnormal architecture of a tissue or[blank_end] organ

4What are the changes that occur in the body after death
1. [blank_start]Cooling[blank_end]
2. [blank_start]Rigor Mortis[blank_end]
3. [blank_start]Blood Changes[blank_end]
4. [blank_start]Post-mortem degeneration[blank_end]- ACooling
- BRigor Mortis
- CBlood Changes
- DPost-mortem degeneration
5Rigor Mortis
Muscles stiffen [blank_start]1-9 hours[blank_end] after death due to contraction [blank_start]of muscles as their supplies of energy[blank_end] decrease.
Order of occurrence: [blank_start]Head[blank_end], [blank_start]Heart[blank_end], [blank_start]Diaphragm[blank_end], [blank_start]Limbs[blank_end]
Disappears in the same order [blank_start]12-30 hours[blank_end] later.
Rigor develops [blank_start]later[blank_end] in well-nourished animals as [blank_start]ATP can still be generated from glycogen[blank_end].
In warm temperatures, [blank_start]glycogen is used more quickly so[blank_end] rigor begins [blank_start]more quickly[blank_end].- A1-9 hours
