- Homeostatus
- Homeostatus is maintaining a constant internal environment
- Levels of CO2
- Water Content
- Body Temperature
- Negative Feedback
- Works to keep everything steady
- It counteracts any changes
- It allows the body to stay at a constant tmeperature over a long period of time
- Body Temperature is controlled by the brain
- Enzymes in the human body work best at 37*
- Thermoregulatory centre - personal thermostat
- Contains receptors that are sensitive to temperature. Receives impulses of change through nervous and hormonal systems to control temperature
- When you are cold
- Little sweat
- Blood vessels near a surface constrict to let less heat out
- When your body drops to low temperatures over a long time you could get hypothermia, which you can die from
- Little sweat
- When your body drops to low temperatures over a long time you could get hypothermia, which you can die from
- Shivering
- When your body drops to low temperatures over a long time you could get hypothermia, which you can die from
- When your body drops to low temperatures over a long time you could get hypothermia, which you can die from
- Hairs stand up to trap heat
- When you are hot
- Hairs lie flat
- High temperatures can lead to dehydration and cause heat stroke which could kill you
- Lots of sweat is produced - cools you down
- High temperatures can lead to dehydration and cause heat stroke which could kill you
- Blood vessels near the surface widen to radiate heat
- Hairs lie flat
- Homeostatus is maintaining a constant internal environment
