- 3. A polymer storage material made from glucose, particularly in liver cells
- 4. A hormone produced by the ovaries which is important in the menstrual cycle.
- 5. A hormone that decreases blood glucose concentration by causing cells to take in glucose. It is used in the treatment of type 1 diabetes.
- 6. A gland that releases the hormone thyroxine into the blood.
- 7. A disease in which the body cannot control blood glucose concentration at the correct level.
- 10. The overall rate at which chemical reactions take place in the body.
- 12. The prevention of pregnancy.
- 14. Organ in the body that produces some digestive enzymes, as well as the hormones insulin and glucagon.
- 15. The ‘bleed’ that occurs during menstruation.
- 19. An organ on which a hormone has an effect.
- 20. A hormone released by the thyroid gland, which affects metabolic rate by changing how certain cells work (e.g. causes heart cells to contract more strongly).
- 23. The release of an egg from an ovary.
- 26. A hormone that is released from the adrenal glands when you are nervous or excited.

- 1. Fusing of a male gamete with a female gamete.

- 17. A monthly cycle involving the reproductive organs in women.
- 18. A structure formed from the egg follicle after an egg cell is released from an ovary. It produces progesterone.
- 20. An organ in the male reproductive system that produces sperm cells and the hormone testosterone.
- 21. An organ just below the brain that controls many activities of the body (e.g. metabolic rate and the menstrual cycle) by the release of hormones into the blood.
- 22. Chemical messenger that is released into the blood from an endocrine gland and causes target cells to change how they work.
- 24. A control mechanism in which a change in a condition, such as temperature, causes the opposite change to happen and so brings the condition back to a normal level.
- 25. The time during which a fertilised egg develops in the uterus until the birth of the baby.
- 28. When the menstrual cycle stops completely.
- 30. Organ in the female reproductive system that releases egg cells and the hormones oestrogen and progesterone.
