ii. Found mostly in sarcomere
1. Glucose is derived from the breakdown of dietary carbs
a. Stored in the LIVER
b. Glucose when not needed stored as glycogen in liver
i. When glycogen needed converted back to glucose an
c. Fats and proteins can generate ATP

✔✔Conduction - ✔✔heat loss or heat gain, w/ physical contact with others
✔✔Convection - ✔✔i. Circulatory medium. Cool breeze will cool body by the body
surface
✔✔Radiant - ✔✔i. Greater in sunshine than in shade. Radiation from something
ii. 65% of body heat is lost through radiation (head and neck 50%)
iii. 20% through evaporation
✔✔Evaporative - ✔✔i. When temperature and radiant heat of the environment become
higher than body temp, the loss of body heat becomes highly dependent on sweat
evaporation
ii. The air must be relatively free of water for evaporation to occur
iii. Heat loss through evaporation is severely impaired when the relative humidity
reaches 65% and virtually stops when humidity reches 75%
iv. When radiant heat and environment temperature are higher than body temperature,
loss of heat through evaporation is key
v. relative humidity of 65% impairs evaporation
vi. relative humidity of 75% stops evaporation
