1. Hormone: Anti-diuretic hormone (ADH) in kidney effect controls blood water level by triggering uptake of water in kidneys.
2. Hormone: follicle stimulating hormone (FSH) in ovaries effect Triggers egg ripening and oestrogen production in ovaries.
3. Hormone: luteinising hormone (LH) in ovaries effect Triggers egg release and progesterone production in ovaries.
4. Hormone: growth hormone (GH) effect speeds up rate of development in children

Show me where your balls are (along with other important glands)
What happens when di addrenaline kicks in?
- breathing rate increases (taking in more o2)
- heart beats faster (sending more blood to muscles)
- blood diverted away from intestine to muscles
- stored carbohydrate changed into glucose
- pupils dilate
- body hair stands on end (make animals look larger than enemy)
- mental awareness increases so reactions are faster
Blood sugar levels
Blood sugar level is controlled by the release and storage of glucose controlled by insulin
a disease where the pancreas cannot make enough insulin to keep blood glucose level constant
(tested by urine test, feeling constant thirst)
