Thermoregulation Flashcards
Define thermoregulation
Body processes that balance heat production + loss
What is the expected body core temp.?
36.2-36.5 C
Hyperthermia: ____ heat produced than lost
more
Hypothermia: ____ heat produced than lost
less
What are 4 factors that affect heat production?
- Basal Metabolic Rate
- Muscle activity
- NE + E
- Fever
What are the 4 methods of heat transfers?
- Conduction
- Convection
- Radiation
- Evaporation
Conduction is ____ contact meanwhile radiation is ____ contact
direct, indirect
What is the internal thermostat in the body?
Hypothalamus
Increased temp. result in:
vaso____ and ____ sweat gland activity
dilation, increased
Decreased temp. result in:
vaso____, ____ sweat gland activity and ____ muscle contraction
constriction, decreased, increased
