What is homeostasis? Give examples
A constant internal environment Body temp (37) Blood pH 7.4 Blood glucose level 100mg/mL
How is homeostasis maintained? Give 3 steps
Negative feedback 1. Sensor detects upset in steady state 2. Signals in a control centre (brain receives message) 3. Activates effector and reverses the change
