Homeostasis Flashcards
(3 cards)
Three structures involved in sweating
- hair
- sweat glands
- capillaries
Changes that occur in hair + capillaries if in a cold environment
- vasoconstriction
- less blood to skin (surface)
- hair erects
- contraction of (erector) muscle
- traps air
- less heat loss
Why do we need to keep body temperature constant
- optimum pH
- for enzymes
(So they won’t denature)
