Answer:
to maintain homeostasis these things must be controlled:
- pH levels in the body (I.e. the stomach)
- wanted levels
- sugar levels
- level of Co2 in our bodies
- blood glucose levels
- body temperature
we maintain homeostasis to ensure that our enzymes, which speed up or make chemical reactions are working well and work within he required conditions.
external things we can do to maintain homeostasis:
- wearing the appropriate clothing in summer and winter
- consuming the correct temperature beverages (i.e. cold drinks in summer)
- consumitn the correct temperature and nutrient required foods (I.e. nutritious pumpkin soup in winter)
we also shiver when we are cold - the friction between our muscles produces heat.
