Adrenals
Produce: adrenalin Targets: kidney Effect: increases heart rate and blood pressure, prepares body for action
Pancreas
Produce: insulin Targets: liver Effect: controls sugar levels; people with diabetes don’t produce enough)
Pituary
Produce: FSH (follicule stimulating hormone) Targets: ovaries Effect: triggers ripening of the egg cell and oestrogen production in ovaries
Testes
Produce: testosterone Targets: testes Effect: stimulates the production of sperm, causes physical changes during puberty in males
Ovaries
Produce: Progesterone, Oestrogen Targtes: Ovaries, uterus (oestrogen) Effect: 1) Maintains the thickend lining in the uterus together with oestrogen 2) Causes physical changes during pubery in females and contols the menstrual cycle.
Thyroid
Produce: thyroxine Target: vital organs (heart, muscles, kidneys, liver) Effect: COntrols the rate of metabolism
