Thermoregulation Flashcards
What Is your Normal Core Body Temperature
37 Degrees Celsius
What is Thermoregulation
Thermoregulation is how the body processes the balance between heat production and heat loss
What is Radiation
Transfer of heat from the surface of one object to the surface of another
How does sweat cool the body down?
- Warm blood below heats sweat
- Sweat Evaporates
- Evaporation is a type of heat transfer
- Heat radiated away from body
Signs of Hypothermia
- shivering.
- pale, cold and dry skin – their skin and lips may be
blue. - slurred speech.
- slow breathing.
- tiredness or confusion.
What type of Animal depends on it’s environment for heat?
Ectotherm
How do Endotherms create their heat?
Metabolic Processes
How would Ectotherms cool and heat themselves?
Moving away or towards a heat source, ECT The Sun
How would Endotherms cool themselves
Glands in their skin secrete sweat
Signs of Hyperthermia
- Blurred vision.
- Dizziness.
- Fast breathing or heart rate.
- Fatigue.
- Headache.
Vasodilation
When blood vessels get wider and send blood to the surface of the skin to help the sweat to evaporate
Vasoconstriction
The narrowing of blood vessels to conserve heat towards the vital organs
How would a bird/mammal maximise heat loss?
Perspiration, Panting, Having fat reserves in one place to avoid insulating effect
Why do we sweat
We sweat because its the main function for us to maintain our body temperature because when the water from our sweat glands evaporate our body begins to cool down
What is Vasoconstriction?
The constriction of blood vessels, which increases blood pressure
