Study Notes
Control and Co-ordination
Definition
- Control refers to the ability of an organism to regulate its internal environment in response to changes in the external environment.
- Co-ordination refers to the integration and regulation of various bodily functions to achieve a common goal.
Importance
- Enables the body to respond to changes in the environment
- Maintains homeostasis (a stable internal environment)
- Allows for efficient use of energy and resources
- Enables adaptation to changing conditions
Control Systems
- Nervous System: receives and interprets sensory information, sends signals to effectors (muscles and glands)
- Endocrine System: produces and regulates hormones, which are chemical messengers that control various bodily functions
Co-ordinating Systems
- Nervous System: integrates and coordinates various bodily functions
- Hormonal System: regulates various bodily functions through hormone production and regulation
Control Mechanisms
- Negative Feedback: a mechanism that reverses the direction of a response to maintain homeostasis
- Positive Feedback: a mechanism that amplifies a response, often resulting in a rapid change
Co-ordination Mechanisms
- Reflexes: automatic responses to specific stimuli, often involving the nervous system
- Voluntary Actions: intentional movements and actions controlled by the nervous system
Examples of Control and Co-ordination
- Thermoregulation (maintaining body temperature)
- Regulation of blood sugar levels
- Control of heart rate and blood pressure
- Co-ordination of movement and balance
