Hormones, glucose and contraception

The idea

Hormones are chemicals secreted by endocrine glands into the blood. The pituitary gland is the 'master gland'. When blood glucose rises, the pancreas releases insulin, which makes cells take up glucose and the liver and muscles store it as glycogen. Type 1 diabetes: the pancreas makes too little insulin (treated with injections). Type 2: cells stop responding to insulin (treated with diet and exercise). Reproductive hormones include oestrogen, progesterone, FSH and LH; contraception uses hormonal and non-hormonal methods.

1. Name the gland and hormone.
2. Describe the effect on the target organ.
3. Compare type 1 and type 2 diabetes.

Watch out Insulin does not 'turn glucose into glycogen' in the blood: it makes liver and muscle cells take up glucose and store it.
