2. You are playing an active game and you begin to sweat. Soon you feel cooler. For this homeostatic system, construct a labelled diagram to represent the feedback loop involved. On the diagram, indicate the receptor(s), the control centre(s), and the effector(s).
Diagram:
Receptor: Thermoreceptors in the skin detect an increase in body temperature.
Control Centre: Hypothalamus in the brain receives signals from the thermoreceptors and coordinates the response.
Effector: Sweat glands are activated by the hypothalamus to release sweat onto the skin.
Feedback Loop:
1. Body temperature increases during physical activity.
2. Thermoreceptors in the skin detect the increase in temperature and send signals to the hypothalamus.
3. The hypothalamus activates the sweat glands to release sweat onto the skin.
4. Sweat evaporates from the skin, cooling the body down.
5. Body temperature decreases and the feedback loop is complete.
