Regulation of Body Temperature (VCE SSCE Biology): Flashcards

Homeostatic process maintaining constant internal body temp

Approximately 37°C

Heat transfer through physical contact with another object

Heat transfer via movement of liquid or gas

Heat loss via conversion of water from liquid to gas form

Heat transfer via electromagnetic waves (e.g. light)

Hypothalamus

Widening of blood vessels (increases surface blood flow)

Narrowing of blood vessels (decreases surface blood flow)

Rapid skeletal muscle contraction to generate heat when cold
