Thermoregulation lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). This is a printer friendly resource it includes an: embedded video, slide animations and a mini exam question.
AQA spec link: 5.2.4
Relevant chapter: B12-Homeostasis in action. ( Note: This topic is for BIOLOGY only not for combined science students). AQA Biology third edition textbook-Page 182-183
*The new specification requires students to know the following;
Body temperature is monitored andcontrolled by the thermoregulatory centre in the brain. The thermoregulatory centre contains receptors sensitive to the temperature of the blood. The skin contains temperature receptorsand sends nervous impulses to the thermoregulatory centre.
If the body temperature is too high, blood vessels dilate (vasodilation) and sweat is produced from the sweat glands.Both these mechanisms cause a transfer of energy from the skin to the environment.
If the body temperature is too low, blood vessels constrict (vasoconstriction), sweating stops, and skeletal muscles contract (shiver).
Students should be able to explain how these mechanisms lower or raise body temperature in a given context.
