Quiz 3 Flashcards
2 types of Post Mortem changes
Physical & chemical
8 signs of death
- Cessation of circulation
- Cessation of respiration
- Complete muscle relaxation
- Algor Mortis: cooling
- Rigor Mortis: stiffening
- Changes in eye, flattening
- Decomp
- Post Mortem lividity
6 Physical Post Mortem Changes
- Algor Mortis
- Hypostasis- action- gravitation of blood
- Dehydration
- Livor Mortis
- Increase in blood viscosity
- Invasion of micros
5 Chemical Postmortem Changes
- Post Mortem caloricity
- Change in body PH
- Rigor Mortis
- Postmortem Stain
- Decomp
2 Types of Cell Death
Necrobiosis
-natural cell death
Necrosis
-diseased cells
Somatic Period
- clinical death
- brain death
- biological death
- cellular death
Define Clinical Death
Somatic Period
Respiration & heartbeat cease
Resuscitation is possible
Define Brain Death
Somatic Period
Respiration & heartbeat cease
5-6 min w/o oxygen
Define Biological Death
Organs fail
Cannot resuscitate
Define Cellular Death
Nutrient & oxygen run out
Cells die
May take hours
Agonal 2 types of “Temp” Change
A)agonal algor
-body temp down, slow death, long illness takes place
B)agonal fever
-body temp up, infections
4 Agonal Period Changes
1.temp change
2.circular changes
3.moisture changes
4 translocation of microorganisms
2 Agonal Moisture Changes
- Agonal Edema
- lots of fluid due to disease - Agonal Dehydration
- no moisture
Agonal 3 Circulatory Changes
- hypostasis-action of blood settling
- coagulation-blood congeals
- capillary expansion-pores of walls expand
Translocation of Micro Steps
Intestinal microbes
Circulatory
& then invade everywhere else
