lgor mortisstomach/intestinal contentsdecompositioninsectsSlide11
Livor mortis refers to:
death coolness
death stiffness
death heatdeath colorSlide12
What is lividity?
Pooling of blood in the bodySlide13
Lividity begins ___ hours after death, and If the skin is pressed, lividity will remain after _________ hours.
2 hours; 6 hours
4 hours; 8 hours2 hours; 12 hours hours
4 hours; 12 hours2 hours; 8 hoursSlide14
Lividity can reveal the position of a corpse during the first 8 hours after death.Slide15
What does dual lividity suggest?
That a body was kept in one position two hours after death and then moved to a second position before the lividity became permanent.Slide16
Rigor mortis is permanent.Slide17
Which statement is true about rigor mortis?
