Inputs for a washing machine:
- Electricity to power the motor, drum, pump and other components
- Water from the water supply
- Detergent and fabric softener added by the user
- User settings for the wash program (hot/cold, water level, spin speed etc)
Outputs from a washing machine:
- Clean clothes
- Wastewater drained out
- Some noise from the motor and drum spinning
The organ-system components of the biological control system for a human are:
Inputs:
- Sensory inputs from eyes, ears, skin, tongue etc which provide information about external environment and internal body states
Components:
- Nervous system (brain, spinal cord, nerves) which processes input and coordinates responses
- Endocrine system (glands) which secretes hormones to regulate processes
Outputs:
The system provides:
- Muscle movements and actions as output responses
- Gland secretions like tears, sweat and saliva as outputs
- Physiological changes in heartbeat, breathing and digestion as outputs
The overall operation is that inputs are detected, processed by the brain and nervous system, which then coordinate output responses via muscles, glands and organs to maintain homeostasis and adapt to the environment. The endocrine system assists the nervous system by secreting hormones that induce slower but longer-term responses.
