Endocrine system

• Made up of endocrine glands 
• Structures that produce chemical systems known as hormones 
• It needs to have a target tissue 
• At the target tissue, it has an effect
• Endocrine gland ----Hormone------> Target ------------> Effects 
• ADH --> produced in the pituitary --> target : collecting duct  --> Increase the H20 in the blood 
• Adrenaline --> Adrenal gland --> The heart, brain, muscles --> Breathing rate, heart rate, muscle strength
• Insulin --> Pancreas --> Controls blood sugar levels --> storage of glucose 
• Testosterone -> testes --> target is the testes --> controls puberty 
• Oestrogen -->  ovary --> controls female puberty, builds the lining of the uterus (produced first) 
• Progesterone --> Ovary --> Maintain uterus lining (produces after oestrogen to maintain the uterus lining) <-- this is only for the mensural cycle, 28 days
