19: The Brothers Mortis Flashcards
How is the vascular system important in thermoregulation in life?
Constricts to retain energy
Dilates to release energy
What happens when in postmortem blood stops flowing?
That’s a physical retention of energy
As a result the body temp increases
What is the postmortem caloricity chemical change?
Some cells continue to metabolize therefore producing energy
Surface area: Mass
Physical build: adipose, protein, developmental stage
Amount of postmortem caloricity
Physical conditions: Autoimmune
Intrinsic factors
Environment
Body coverings
Pathological conditions: viral or bacterial
Controlled substances
Extrinsic factors
What is an intrinsic factor?
Variables that are inherent to body
What is an extrinsic factor?
Variables outside the body
What kind of change is Rigor Mortis?
Chemical change
What is an initial flaccidity
Shortly after death ATP is present in body
What is second flaccidity
After long period of time muscle protein decomposes
What kind of change is Livor Mortis?
Physical change
What kind of discoloration is Livor Mortis
An intravascular discoloration
What kind of change is Post Mortem stain?
Chemical change
What kind of discoloration is Post Mortem stain?
An extravascular discoloration
Hypostasis
Liver Mortis
Hydrolyses
Hemolysis
Post Mortem Stain
Discoloration Process
Physical Change
Postmortem slowing of blood in vascular system
*Can also occur as part of pathological process prior to death
Hypostasis
As blood settles in vascular system body fluids cause vessels to dilate and become permeable
Liver Mortis
Chemical Change
Breaks down dependent vessels and tissues, red blood cells go into tissue and further settle due to gravitation
Hydrolyses
Chemical change
Chemical Breakdown of red blood cells
Hemolysis
Evident in tissue as hemeaccumulates in tissue
Post Mortem Stain
What kind of change is Decomposition?
Chemical change
