Body Temperature

HideShow resource information
What regulates the core body temperature
Homeostatic mechanisms
1 of 7
Define homeostasis
Ability of an organism to maintain an internal environment, regardless of the external environment by adjusting physiological processes
2 of 7
When temperature rises, what does the body do to lose heat
Divert blood to skin, produce sweat to lose heat through evaporation, vasodilation lose heat through radiation
3 of 7
What other mechanisms lose heat
Exhaling air, excretion, vomiting
4 of 7
What factors can affect our ability to lose heat
Temperature or surroundings, Temperature of the air, Humidity, Air movement, Amount of clothes worn, Activity, Body area exposed
5 of 7
How does the body raise temperature
Shivering, increase metabolic rate, increase respiration rate
6 of 7
How does the body prevent heat loss
Piloerection (making hairs erect), vasoconstriction (diverting blood from skin)
