AQA GCSE Biology-Hormones in human reproduction

(0)
Designed for the new specification AQA GCSE( covers spec point 4.5.3.4 ) course but can be modified for other exam boards. 23 slides covering Hormones in human reproduction: By the end of the powerpoint students would have covered: 4.5.3.4 Hormones in human reproduction Students should be able to describe the roles of hormones in human reproduction, including the menstrual cycle. During puberty reproductive hormones cause secondary sex characteristics to develop. Oestrogen is the main female reproductive hormone produced in the ovary. At puberty eggs begin to mature and one is released approximately every 28 days. This is called ovulation. Testosterone is the main male reproductive hormone produced by the testes and it stimulates sperm production. Several hormones are involved in the menstrual cycle of a woman. Follicle stimulating hormone (FSH) causes maturation of an egg in the ovary. Luteinising hormone (LH) stimulates the release of the egg. Oestrogen and progesterone are involved in maintaining the uterus lining. (HT only) Students should be able to explain the interactions of FSH, oestrogen, LH and progesterone, in the control of the menstrual cycle. (HT only) Students should be able to extract and interpret data from graphs showing hormone levels during the menstrual cycle. Contains examination questions Alternative starter question for triple or combined science students.

AQA GCSE Biology- Human endocrine system

(0)
www.mrscience.co.uk Designed for the new specification AQA GCSE course but can be modified for other exam boards. 25 slides covering the human endocrine system. By the end of the powerpoint students would have covered: **4.5.3.1 Human endocrine system ** Students should be able to describe the principles of hormonal coordination and control by the human endocrine system. The endocrine system is composed of glands which secrete chemicals called hormones directly into the bloodstream. The blood carries the hormone to a target organ where it produces an effect. Compared to the nervous system the effects are slower but act for longer. The pituitary gland in the brain is a ‘master gland’ which secretes several hormones into the blood in response to body conditions. These hormones in turn act on other glands to stimulate other hormones to be released to bring about effects. Students should be able to identify the position of the following on a diagram of the human body: pituitary gland pancreas thyroid adrenal gland ovary testes. Contains examination questions
