Applied ScienceEnergy TransferASAQA Created by: WilliamHamiltonCreated on: 10-04-16 16:47 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) 7 of 7
