- 1what is the definition of homeostasis?it is to help our internal enviroment to be stable, with sudden changes from external enviroment.
- 2what is dynamic homeostasis?This is when the body keeps it's equilibrum constantly balance, to keep the body functioning at it's normal ranges

- 5what are the two mechanism of homeostatic regulation?autoregulation and extrinsic regulation
- 6How does autoregulation work?This work by responding to some enviroment changes, where the organs or tissues adjust itself, to keep a constant internal enviroment. For example, low oxygen level increase chemicals which widens blood vessels to have more blood flow, meaning more oxygen delivered to cells that needs it.
- 7what is extrinsic regulation?This reacts to any enviromental changes. it involves Nervous system releasing electrical signal to parts of the body or endocrine releasing chemical messenger, to keep a constant internal enviroment
