Human Performance 30 15:51 Depth Time:100’ 60’   20’ 10’ 9mm 28m = 37min Temperature Regulation Homeotherm: organism that maintains a constant core temp despite change in  ambient temperature. Advantage you can go anywhere: the con is that 60% of  the energy of carbs and protein is wasted as heat energy. Pro: you can go  anywhere. Poikilothem – core temp dependant on ambient temperature: you are a slave of  the environment.  Temperatures: (extremities toes and fingers high 80’s), (blood supply trunk, skin,  and head low 90’s): Rectal temperature  98.6  (37C). Muscle temperature can  exceed 101-103, it depends if you are exercising does not reflect core  temperature. Liver temperature is always 100 degrees since its always metabolic  active and close to a blood supply.  Internal “Range”:  hyperthermia High Limit 107-108 above brain damage.  Hyperthermia is common = people do exercise at high temps. Lower hypothermia 80 degrees . Would be unconscious, heart goes into  fibrillation. The normal is 98.6F. Hypothermia is not common and its always a  survival situation. Additive: we are like a radiator we expel heat.
