Thermoregulation & Homeostasis

Thermoregulation & Homeostasis

1. Controlled by the HYPOTHALAMUS in the brain

   • The HYPOTHALAMUS detects a change in temperature of the blood and reacts upon this change

2. Homeostasis

   • A process in the body which maintains conditions within certain limits
     • Controls
       • Temperature
       • CO2
       • Glucose
       • Water
       • Salts
       • pH
   • Negative Feedback
     • The body ensures it stays within certain limits by reversing a change
     • Example
       • The Body temperature goes above/ below 37^C
         • The hypothalamus detects this change & starts the heating/cooling mechanisms until temperature is returned to normal

3. Body Temperature

   • If body temperature increases too much enzymes begun to denature
   • If body temperature decreases too much you can become unconsious or die
