<u>Explanation:</u>
Homeostasis refers to the internal body system that helps to regulate our internal body environment, such as our temperature, blood pressure, etc.
By means of<em> internal sensors</em> which monitor when there is a change in our normal body condition, these reaction times occur for example:
- when we are triggered by our body to go and dehydrate (urinate) in the restroom,
- or maybe when we begin to sweat heavily after performing physical activity, those tiny droplets of sweat helps cool our body down.
All these automatic responses help us maintain homeostasis in our body.
