body temperature- lqc 1a Flashcards
what is the normal range for the human body temp
36.2-37.6°c
what happens immediately after death
the body starts to cool due to the absence of heat producing chemical reactions
what is a heat producing chemical reaction
respiration
what type of curve does body cooking follow on a graph
a sigmoid curve
how long is body temp useful for in determining time of death
the first 24 hours
what is assumed of the body when calculating the time of death
the body was at normal temperature (36.2-37.6°c) at death
when might the body temperature not be normal at death
if person is suffering from fever or hypothermia
when using body temperature to determine the time of death what else needs to be recorded?
the ambient (environmental) temperature, body size, body position, status of clothing, air movement, humidity, whether the body was immersed in water, general surroundings (inside or out)
body temp - time graph
describe the body temp graph
after death, metabolic reactions that produced body heat slow and eventually stop (sigmoid curve), heat is also transferred from the body surface to the environment by radiation, conduction and water evaporation
