Thermoregulation Flashcards
1. Process of maintaining body's core temperature within an optimal range: -
Thermoregulation
2. Precursor for body temperature regulation, located in the brain: Normal hypothalamus
function
3. Heat generation through metabolic processes: Chemical thermogenesis
4. Essential for cooling the body through perspiration: Normal sweat gland function
5. Necessary for generating heat through movement: Normal skeletal muscle function
6. Critical for distributing heat throughout the body: Sufficient blood flow
7. Important for maintaining warmth in infants: Adequate brown fat in the new- born
8. Range for body temperature considered normal: 36.5° - 37.2° C or 97.7° -
98.96° F
9. Deep tissue temperature, remains constant: Core body temperature
10.Outer tissue temperature, varies with environment: Surface (external) tem- perature
11.Involves brain's control for heat loss and production: Role of hypothalamus
12.Heat reduction through perspiration and blood vessel dilation: Mechanisms of heat loss
13.Heat retention through blood vessel constriction and shivering: Mecha- nisms of heat
conservation
14.Increase in body's temperature set point: Effect of changing set point
15.By-product of body metabolism, increases with activity: Heat production
16.Primary source for metabolic heat generation: Food
17.Heat production at rest, indicates body's metabolic health: Basal Metabolic Rate
18.Involuntary response to cold, generates heat: Shivering
19.Heat generation in newborns without shivering: Non-shivering thermogene- sis
20.Transfer of heat without direct contact: Radiation
21.Heat transfer through direct contact: Conduction
22.Heat removal by air movement: Convection
23.Body heat loss through sweat evaporation: Evaporation
24.Strategy to increase heat loss, by reducing insulation: Increase heat loss by removing clothing
25.Strategy to decrease heat loss, by increasing insulation: Decrease heat loss by covering with
clothing and blankets

, Thermoregulation Flashcards
26.Body's physiological and behavioral response to regulate heat balance: -
Thermoregulation involves balancing heat production and loss
27.Appearance and activity increase when body temperature rises: Blood vessels dilate and
sweat glands activate during increased temperature
28.Response of the body to decreased temperature: Blood vessels constrict, sweat glands
deactivate, and skeletal muscles contract causing shivering
29.Antecedent: Key for initiating body temperature regulation: Hypothalamus functions normally
30.Mechanism essential for generating warmth without shivering, especially in infants: Chemical
thermogenesis occurs
31.A sign of body maintaining temperature within a safe range: Normothermia at 36.5° - 37.2° C
(97.7° - 98.96° F)
32.Core components crucial for sustaining metabolic rate: Heart, brain, liver, kidneys help
maintain core body temperature
33.Difference between core and surface body temperatures: Core temperature remains constant;
surface temperature varies
34.Neural and vascular control as a means of: Regulating body temperature through heat
production and loss
35.Hormonal thermostat in the brain: Hypothalamus controls body temperature
36.Transition of body temperature's set point and its effects: Chills, vasocon- striction,
piloerection, epinephrine secretion, shivering during set point increase
37.Primary fuel for metabolic heat production: Food
38.Basal condition indicating metabolic heat at rest: Basal Metabolic Rate
39.Spontaneous heat production method in neonates: Non-shivering thermo- genesis in vascular
brown fat
40.Heat dissipation methods: Radiation, conduction, convection, evaporation
41.Heat loss through air movement: Convection removes radiated heat
42.Strategy to maximize heat emission: Increase heat loss by removing clothing enhances
radiation
43.Strategy to minimize heat emission: Decrease heat loss by covering with dark, closely
woven clothing and blankets
44.Process of transferring body heat through direct touch: Conduction is how heat moves from
warm skin to a cool object, resulting in temperature change
45.Movement of air that enhances body heat loss: Convection uses air move- ment, like a fan,
to reduce body temperature
46.How the body loses heat when liquid turns to gas: Evaporation occurs as sweating converts
liquid to gas, cooling the skin
47.Role of skin in regulating internal temperature: The skin insulates the body, adjusting blood
flow and detecting temperature changes
