B1.2.2 Control in the human body B1 Lesson 15 Hormones
b Hormones are chemical produced by glands and transported to target organs in the blood. Explain what hormones are.
c Hormonal control of the menstrual cycle – FSH, LH and oestrogen. Give some changes that occur at puberty and link with secretion of hormones.
d Describe the function of FSH, LH and Oestrogen and state the glands that produce them.


b) Many processes within the body are coordinated by chemical substances called hormones. Hormones are secreted by glands and are usually transported to their target organs by the bloodstream.

c) Hormones regulate the functions of many organs and cells. For example, the monthly release of an egg from a woman’s ovaries and the changes in the thickness of the lining of her womb are controlled by hormones secreted by the pituitary gland and by the ovaries.
d) Several hormones are involved in the menstrual cycle of a woman. Hormones are involved in promoting the release of an egg:
■ follicle stimulating hormone (FSH) is secreted by the pituitary gland and causes eggs to mature in the ovaries. It also stimulates the ovaries to produce hormones including oestrogen
■ luteinising hormone (LH) stimulates the release of eggs from the ovary
■ oestrogen is secreted by the ovaries and inhibits the further production of FSH.
