What is the main role of the pancreas in the endocrine system?
Controls blood glucose levels
Controls growth in children
Stimulates the thyroid gland
Controls the menstrual cycle
Which of the following is NOT controlled by negative feedback?

Which gland stimulates the ovaries to produce and release eggs in females?
Pituitary gland
Thyroid gland
Adrenal gland
Pancreas
What is the role of the testes in the endocrine system?
Controls the development of male secondary sexual characteristics
Controls the menstrual cycle
Controls blood glucose levels
Controls the rate of metabolism
Which gland controls the development of female secondary sexual characteristics?
Ovaries
Testes
Pancreas
Thyroid gland
Which hormone is released when blood glucose levels fall too low?
Glucagon
Insulin
Adrenaline
Thyroxine
Which hormone is mainly responsible for the development of secondary sex characteristics in females during puberty?
Oestrogen
Testosterone
Progesterone
FSH
Which gland releases follicle stimulating hormone (FSH)?
Pituitary gland
Ovaries
Testes
Thyroid gland
What is the role of oral contraceptives in hormonal contraception?
Inhibit FSH production so no eggs mature
Increase sperm production
Stimulate ovulation
Cause menstruation to stop
What does the copper IUD do to prevent pregnancy?
Prevents the implantation of an embryo
Inhibits FSH production
Stimulates ovulation
Maintains the uterus lining
Why might IVF treatment lead to multiple births?
More than one embryo may be inserted into the uterus
It always produces twins
It uses only one egg
It prevents fertilisation
What is the function of FSH?
Causes eggs to mature in the ovaries and stimulates ovaries to produce oestrogen
Stimulates the release of an egg
Increases heart rate
Causes lining of uterus wall to thicken
What is the function of oestrogen?
Causes lining of uterus wall to thicken
Increases heart rate
Stimulates the release of an egg
Regulates blood glucose
What are the methods of hormonal contraception?
Oral contraceptives, injection, implant, skin patch, IUD
Barrier methods, copper IUD, spermicidal agents
Abstinence and sterilisation
Withdrawal and rhythm method
What is the function of adrenaline in the body?
Increases heart rate and boosts delivery of oxygen and glucose to brain and muscles for 'fight or flight'
Causes lining of uterus wall to thicken
Stimulates the release of an egg
Regulates blood glucose levels
Name one hormone controlled by negative feedback.
Thyroxine
Insulin
Oestrogen
Adrenaline
Why might IVF treatment lead to risky multiple births?
Because multiple embryos may be implanted
Because it increases heart rate
Because it stimulates basal metabolic rate
Because it causes eggs to mature in the ovaries
Which gland produces hormones that regulate metabolism?
Pituitary gland
Testes
Ovaries
Thyroid gland
