B7.3 Peak performance - energy balance
1. To maintain a constant body temperature, briefly state the relationship between heat
gained (including heat released during respiration) and heat lost.
2. What do temperature receptors in the skin detect?
3. What do temperature receptors in the brain detect?
4. Where in the brain do you find the processing centre which receives information from
the temperature receptors, and sends instructions to trigger the effectors automatically.
5. Name two effectors involved in temperature regulation.
6. Describe what happens to the body at high temperatures.
7. During exercise the body produces more sweat. What negative effect can this have on
the body?
8. Describe what happens to the body at low temperatures.
9. Explain with examples that some effectors work antagonistically, which allows
a more sensitive and controlled response.
10. What type of foods are quickly absorbed into the blood stream, causing a rapid rise
in the blood sugar level?
11. Which type of diabetes is more likely to arise because of poor diet or obesity?
12. Which type of diabetes arises when the pancreas stops producing enough of the
hormone, insulin? And which type of diabetes develops when the body no longer
responds to its own insulin or does not make enough insulin?
13. Describe how each type of diabetes can be controlled.
