- Temperature Control

- Waste products and removal, eg. carbon dioxide, urea, water and ions

HOWEVER controlling blood glucose concentration and diabetes are NOT in here, as I have much better notes on those separately. 

Hope its helpful!

body via the lungs when we breathe out)
Urea (produced by the liver in the breakdown of excess
amino acids, removed…

Temperature receptors in the skin send impulses to the centre giving
it information about the skin temperature.

To cool down: Sweat glands release more sweat.
This cools the body while the sweat evaporates from
the skin using the body's heat. More water is lost when it
is hot, and more…
