- Homeostasis
- This is important as cells need the right conditions to function properly
- The conditions in your body need to be kept steady even when the external environment changes.
- Made up of three main components
- 1) Receptors
- 3) Coordination centres
- 4) Organises a response
- 3) Coordination centres
- 1) Receptors
- Your body has lots of automatic control systems.
- e.g. nervous an hormonal communication
- e.g. Blood glucose levels, water levels and body temperature
- e.g. nervous an hormonal communication
- Homeostasis is the process of maintaining a stable environment.
- Negative feedback counteracts change
- This is an automatic response
- Effectors will continue to produce responses as long as they are stimulated by the coordination centres
- A stimulus is a change in environment
- 2) Detects a stimulus level is too high
