Detailed notes on Homeostasis (B3.3) in GCSE Biology. Enjoy!

- waste products, water balance, kidney, and kidney failure (dialysis and transplants)
B3.3.2: Temperature Control
- thermoregulatory centre, increases in temperature (sweating, vasodilation, pilorelaxation), and falls in temperature (shivering, vasoconstriction, piloerection)
B3.3.3: Sugar Control
- glucose, rising blood sugar (pancreas, hormone, insulin, glycogen, liver), falling blood sugar (glucagon), and diabetes (type 1, type 2 (but mostly focusing on type 1 as that's what's in the specification))
