The adrenal glands are small structures attached to the top of each kidney. The human body has two adrenal glands that release chemicals called hormones into the bloodstream. These hormones affect many parts of the human body.
Coordination and Control Key Stage 4 Age 14 - 16The hypothalamus is a part of the brain that has a vital role in controlling many bodily functions including the release of hormones from the pituitary gland.
Coordination and Control Key Stage 4 Age 14 - 16The kidneys are specialised organs that ensure that unwanted substances and excess water are removed from the bloodstream.
Coordination and Control Key Stage 4 Age 14 - 16The ovaries produce and release eggs (oocytes) into the female reproductive tract at the mid-point of each menstrual cycle. They also produce the female hormones oestrogen and progesterone.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16The pancreas is an organ that serves two vital purposes: to aid food digestion and to produce hormones that mainly serve to control levels of energy in the blood.
Coordination and Control Health: Non-communicable Diseases Age 14 - 16 Key Stage 4The pituitary gland is a small pea-sized gland that plays a major role in regulating vital body functions and general wellbeing. It is referred to as the body's 'master gland' because it controls the activity of most other hormone-secreting glands.
Coordination and Control Key Stage 4 Age 14 - 16The placenta is a temporary endocrine organ formed during pregnancy, which produces hormones important in the maintenance of a healthy pregnancy and in preparation for labour and breastfeeding.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16The testes are two oval-shaped male reproductive glands that produce sperm and the hormone testosterone.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Adrenaline is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for 'fight or flight'.
Coordination and Control Key Stage 4 Age 14 - 16Adrenocorticotropic hormone (ACTH) is produced by the pituitary gland. Its key function is to stimulate the production and release of cortisol from the cortex (outer part) of the adrenal gland.
Coordination and Control Key Stage 4 Age 14 - 16Anti-diuretic hormone acts to maintain blood pressure, blood volume and tissue water content by controlling the amount of water and hence the concentration of urine excreted by the kidney.
Coordination and Control Key Stage 4 Age 14 - 16Anti-Müllerian hormone is a protein hormone which is important in the development of the reproductive tract in a male foetus and is also produced (before birth) by the testes and ovaries.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Cortisol is a steroid hormone that regulates a wide range of processes throughout the body, including metabolism and the immune response. It also has a very important role in helping the body respond to stress.
Coordination and Control Key Stage 4 Age 14 - 16Follicle stimulating hormone is produced by the pituitary gland. It regulates the functions of both the ovaries and testes. Lack or insufficiency of it can cause infertility or subfertility both in men and women.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Ghrelin is produced by the stomach. Among its numerous functions, ghrelin increases appetite and stimulates the release of growth hormone.
Health: Non-communicable Diseases Key Stage 4 Age 14 - 16Glucagon is produced to maintain glucose levels in the bloodstream when fasting and to raise very low glucose levels.
Coordination and Control Key Stage 4 Age 14 - 16Growth hormone is produced by the pituitary gland. It has many functions including maintaining normal body structure and metabolism.
Human chorionic gonadotrophin is a reproductive hormone that is essential for establishing and maintaining early pregnancy.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Insulin is an essential hormone produced by the pancreas. Its main role is to control glucose levels in our bodies.
Coordination and Control Health: Non-communicable Diseases Key Stage 4 Age 14 - 16Luteinising hormone is produced by the pituitary gland and is one of the main hormones that control the reproductive system.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Oestradiol is a powerful reproductive hormone that has a wide range of actions in both men and women.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Oestriol is a hormone made during pregnancy that can be used to measure fetal health and predict when birth may happen.
Human Reproduction Key Stage 4 Age 14 - 16Oestrone is a hormone produced by the ovaries. It is one of the major oestrogens in postmenopausal women.
Human Reproduction Key Stage 4 Age 14 - 16Parathyroid hormone is secreted by the parathyroid glands and is the most important regulator of blood calcium levels.
Progesterone is a hormone released by the corpus luteum in the ovary. It plays important roles in the menstrual cycle and in maintaining the early stages of pregnancy. It may also be involved in the growth of certain cancers.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Relaxin is a hormone produced by the ovary and the placenta with important effects in the female reproductive system and during pregnancy. In preparation for childbirth, it relaxes the ligaments in the pelvis and softens and widens the cervix.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Testosterone is a hormone that is responsible for many of the physical characteristics specific to adult males. It plays a key role in reproduction and the maintenance of bone and muscle strength.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Thyrotropin-releasing hormone is produced by the hypothalamus. It plays an important role in the regulation of thyroid gland activity.
Age 11 - 14 Age 14 - 16 Coordination and ControlAcromegaly is a condition that develops due to overproduction of growth hormone, usually caused by a benign tumour of the pituitary gland. It leads to an increase in size of the hands and feet, a change in the appearance of the face and enlargement of the internal organs.
Carcinoid tumours are slow-growing tumours that arise from specialised cells that release hormones.
Health: Non-communicable Diseases Key Stage 4 Age 14 - 16Delayed puberty is defined as no secondary sexual maturation or any sign of puberty by the age of 13 years in girls and 14 years in boys.
Human ReproductionDiabetes insipidus (water diabetes) is a rare condition caused by a reduction in, or failure to respond to, anti-diuretic hormone. This results in passing large amounts of dilute urine and increased thirst.

Health: Non-communicable Diseases Key Stage 4 Age 14 - 16Gestational diabetes is development of high blood sugar (glucose) levels during pregnancy. Strict blood glucose control in pregnant women improves outcomes for both the mother and child.
Coordination and Control Age 14 - 16 Key Stage 4Hyperthyroidism is a common condition where the thyroid gland becomes overactive and produces too much thyroid hormone.
Human Reproduction Coordination and Control Health: Non-communicable DiseasesThe menopause is the time when menstruation stops because the ovaries stop producing hormones and releasing eggs for fertilisation. This marks the end of a woman's reproductive years.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Obesity is an excess of calories stored in the form of fat. It is an increasing public health and medical problem associated with reduced quality and length of life.

Health: Non-communicable DiseasesThis article describes hormones that play an important role in pregnancy and labour.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16Growth of the fetus during pregnancy is regulated by a balance of hormones.
Human Reproduction Key Stage 3 Key Stage 4 Age 11 - 14 Age 14 - 16In vitro fertilisation is a fertility treatment which stimulates the ovaries to produce multiple eggs which are collected and fertilised by sperm outside of the body in the laboratory to create embryos. One or two of which are then selected and transferred back to the womb in order to result in pregnancy.
Human Reproduction Health: Non-communicable Diseases Age 14 - 16 Key Stage 4The menstrual cycle is governed by an interaction between reproductive hormones which prepares the endometrium (or womb) for pregnancy, or if no pregnancy occurs, the fall in progesterone leads to shedding of the endometrial lining and recommences the monthly cycle.
