The endocrine system, key hormones, hormonal feedback, and a comparison with nervous control.
The endocrine system
Hormones are chemicals made by glands and carried in the blood to target organs. Key examples:
Insulin/glucagon (pancreas) — blood glucose.
Adrenaline (adrenal glands) — "fight or flight": raises heart rate and blood glucose.
Oestrogen/testosterone — sexual development and reproduction.
ADH (pituitary) — water balance.
