In about 6 paragraphs explain the actions of different types of hormones in our bodies and how people view hormones in general
Hormones are chemical substances which co ordinate the activities of living organisms and also their growth.They are secreted by special tissues in our body through endocrine glands. Different hormones have different effects on the body.Below are the list of different hormones and their functions:
1. Thyroid hormones : The Thyroid is a butterfly-shaped gland that sits low on front of the neck.Thyroid gland releases two hormones TRIIODOTHYRONINE (T3) and THYROXINE(T$) which helps in controlling the body metabolism.Further these regulate weight,determines energy levels,internal body temperature , skin , hair etc.

2.Insulin: This is released by pancreas, a leaf like gland located in the abdominal cavity behind the stomach.It allows the body to use glucose or sugar from carbohydrates in the food for energy or to store glucose for future use.It helps in keeping the blood sugar level from getting too high(hyperglycemia or too low (hypoglycemia)
3. Estrogen : It is a female sex hormone released by ovaries.It is responsible for reproduction,menstruation and menopause.Excess of estrogen in the female body increases the risk of breast cancer,uterine cancer,depression,modiness etc.If this hormone is less in female it leads to acne,skin lesions,thinning skin,hair loss etc.
4.Progesterone : This hormone is produced in the ovaries in placenta when a woman gets pregnant.It plays an important role in maintaining pregnancy.It helps body to prepare for conception,pregnancy and regulates the the monthly cycle.When pregnancy does not occur, the progesterone levels drop and menstrual cycle occurs.It also plays a role in sexual desire.
5. Prolactin : This is released by pituitary gland after child birth for lactation, which enables female breast feed.Levels of prolactin rises during pregnancy and plays an important role in fertility by inhibiting follicle stimulating hormones and gonadotropin releasing hormone.
6. Testosterone : It is a male sex hormone.It is an anabolic steroid by nature which helps in building body muscles.In males it plays an important role in the development of male reproductive tissues; testes and prostrate.It also promotes secondary sexual characteristics like increasing the mass of muscles and bones, growth of body hair etc.
7. Serotonin: It is a mood boosting effect hormone or also known as nature's feel good chemical.It is associated with learning and memory, sleep, digestion, some muscular functions etc.Due to reduced serotonin hormone brain cannot regulate stress or mood levels and may cause depression,migraine, weight gain, insomnia, craving of carbohydrate.
8. Cortisole: This hormone is produced by the adrenal gland. It helps to stay healthy and energetic. Its main role is to control physical and psychological stress. In danger condition it increases heart rate, blood pressure, respiration , etc. At stressful times body secretes Cortisole to cope up with the situation. High levels of this hormone causes ulcer, high blood pressure, anxiety, etc. and low level causes alcoholism, condition responsible for a chronic fatigue syndrome.
9. Adrenaline: This hormone is secreted in the medulla in the adrenal gland as well as some of the neurons. It initiates the quick reaction to think and respond quickly to the stress hence it is also known as Emergency hormone. It increases the metabolic rate, dilation of blood vessels going to the heart and brain. During stressful situation it is released into the blood to create a specific response.
10. Growth Hormone: Also known as Somatotropin hormone secreted by Pituitary glands. It stimulates growth, cell reproduction, regeneration and in boosting metabolism. It is important in human development.
So, now you may have come to know about various hormones and their functions in the human body.
