Document Summary
The core body temperature of the organism in question. Thermoreceptors on body measure the tb and sends into to brain to integrate info and compare to set point. Using behavioural, biochemical, and physiological responses to regulate tb. Ectothermy - conformers, external environment for source of heat. Seasonal variations --> compensation by being less active in cold --> less food bc less energy need. Temp does not vary with ambient (produce your own heat) Can remain active in a broader ambient temp. When inactive = allow core temp to fluctuate with environment. Large snakes - accelerate metabolism for digestion other biological processes. Endo and ecto thermy is for how heat is gained. Homeo and poikilo is how body temperature fluctuates. On region of an object (or fluid) to another region. Thermal conductivity, fat vs water, insulation vs heat sinks. Black and brown pigments to absorb thermal energy. Between an object and the external fluid that is moving.
