The hormones chemical compounds produced by the endocrine glands into the bloodstream, these compounds control various functions and vital processes in the body, such as regulating heart rate, and the process of metabolism through which generate the necessary to carry out various body functions of the energy intake of foods, and control appetite, mood, different sexual functions, and the process of reproduction, growth, development, regulation of the process of sleep, and many other functions. 
There are many endocrine glands that secrete hormones, and is part of the endocrine system, and these glands are the following: 
- Hypothalamus: (English: Hypothalamus) This is the gland responsible for the body temperature, hunger, thirst, mood, sleep, and sex, as it is responsible for regulating the secretion of hormones from other glands.
- Parathyroid: (glands in English: Parathyroid gland) control these glands in the amount of calcium in the body.
- Gland Azaatarah: (English: Thymus) produces this gland T cells, as well as they play a role in regulating the function of adaptive immune system.
- Pancreas: (English: Pancreas) produces this gland insulin, which regulates blood sugar levels.
- Thyroid: (English: Thyroid gland) associated with thyroid hormones to burn calorie intake and the rate of heart beat.
- Adrenal gland: (English: Adrenal gland) of the adrenal glands produce hormones that control sexual desire, in addition to the secretion of the hormone cortisol, a hormone that is secreted in a state of tension.
- Pituitary gland: (English: Pituitary gland) called the pituitary gland lady endocrine, where regulates the work of other glands, and they secrete a hormone stimulating growth.
- Pineal gland: (English: Pineal gland) This produces a hormone that affects sleep gland.
- Ovaries: (English: Ovaries) secrete the ovaries in women of many hormones, including estrogen (in English: Estrogen), testosterone (in English: Testosterone), and progesterone (in English: Progesterone).
- Testicles: (English: Testes) secrete testicles male sex hormones such as testosterone, in addition to the production of sperm.
The functions of hormones
Thyroid hormones parathyroid
Glands secrete parathyroid hormone neighbor thyroid, which increases the concentration of calcium at low levels in the blood, as this hormone stimulates bone cells to release calcium from the bones to the blood, and reduces the loss of calcium through the urine, and stimulates the production form of active vitamin D in the kidneys, which facilitates the absorption of calcium from the intestine. 
Secreted by the pancreas hormone insulin as we mentioned earlier, which regulates many vital processes in the body, and these operations as follows: 
- Metabolic processes, and get energy from food intake.
- Storage of glucose in fat cells, muscle, and liver cells to be used as needed.
- Help the body's cells to make use of glucose as an important source of energy.
- Help the liver cells to fatty acids manufacturing.
Hormones affect the thyroid gland in all parts of the body, and in a statement that comes in detail: 
- Regulate metabolic processes: it stimulates the thyroid hormones many metabolic processes, causing an increase rate of basal metabolic (in English: Basal metabolic rate), as it stimulates the thyroid hormones processes fat metabolism, leading to increased concentration of fatty acids in the blood, and regulates carbohydrate metabolism through promote the entry of sugar into the cells under the influence of the hormone insulin, and stimulates the manufacture of sugar and glycogenolysis (in English: glycogenolysis) to increase the level of sugar in the blood.
- Evolution: The thyroid hormones are essential for the development of the brains of fetuses and newborns.
- Growth: The thyroid hormones along with growth hormone necessary to complete the process of growth in children naturally and properly, as a lack of thyroid hormones leads to growth retardation.
- Other roles: there is almost no organ of the body does not affect the thyroid gland, and other functions of the thyroid gland as follows: Regulate the work of the heart and blood vessels: thyroid hormones increase heart rate and strength of contraction, allowing blood to pump a larger quantity, it also promotes the expansion of blood vessels, which leads to enhance blood flow to many members. Regulate central nervous system: affect thyroid hormones in mental status, with low lead concentration of these hormones to slow mental processes, while increasing lead to feelings of anxiety and nervousness. Regulate reproductive system: thyroid hormones affect the ability to have children, have low levels of which lead to infertility.
- Regulate the work of the heart and blood vessels: thyroid hormones increase heart rate and strength of contraction, allowing blood to pump a larger quantity, it also promotes the expansion of blood vessels, which leads to enhance blood flow to many members.
- Regulate central nervous system: affect thyroid hormones in mental status, with low lead concentration of these hormones to slow mental processes, while increasing lead to feelings of anxiety and nervousness.
- Regulate reproductive system: thyroid hormones affect the ability to have children, have low levels of which lead to infertility.
Hormones of the adrenal gland
The adrenal gland produces many hormones such as cortisol, which regulates cortisol many of the functions of the body, which regulates the hormone cortisol, the body's response to hazardous situations, and stimulates glucose metabolism processes, and regulates blood pressure in the body, and that the amount of inflammation in the body reduces,  It should be noted that the adrenal gland produces hormone aldosterone, which regulates blood pressure through a variety of roles, as it increases the concentration of sodium through the re-absorbed from the kidneys and colon, also increases the absorption of water from the kidneys, and it increases blood volume, which leads to high blood pressure. 
Hormones of the pituitary gland
The pituitary gland produces several hormones, which affect many of the glands and cells, and these hormones as follows: 
- Adrenocorticotropic hormone: (English: Adrenocorticotrophic hormone) and Acronym ACTH, the hormone stimulates the adrenal gland to secrete the hormone cortisol.
- Thyroid-stimulating hormone: (English: Thyroid-stimulating hormone) and Acronym TSH, this hormone stimulates the thyroid gland to secrete hormones.
- Stimulating hormone to the body yellow: (English: Luteinising hormone) and Acronym LH, and follicle-stimulating hormone (in English: Follicle-stimulating hormone) controls these hormones in the reproductive process of sexual characteristics, as are prompting the ovaries to produce estrogen and progesterone, and the testes to produce testosterone and sperm.
- Prolactin: (English: Prolactin) stimulates the breast of this hormone to produce milk, and increasing the quantity considerably during pregnancy and breastfeeding.
- Growth Hormone: (English: Growth hormone) stimulates the hormone growth and regeneration of damaged cells.
- Oxytocin: (English: Oxytocin) This affects hormone in the uterine contractions during childbirth and helps milk secretion after.
Hormones genital glands
- Hormone estrogen: stimulates the hormone estrogen, follicle growth during the development of the egg, and stimulates the vagina growth to its normal size at puberty, increases the thickness of the wall of the vagina, increases the acidity of the vagina, which reduces the incidence of bacterial infection, and keeps estrogen on the mucous membrane lining the uterus, increases the size of the the lining of the uterus, and enhances the blood to flow, and stimulates the muscles of the uterus to contract during childbirth. 
- Hormone progesterone helps the hormone progesterone to prepare the lining of the womb to receive the fertilized egg pregnancy and the start of the process, it also prevents the occurrence of ovulation during pregnancy, the growth of milk-producing glands and stimulates the breast during pregnancy, as well as it regulates the menstrual cycle. 
- Testosterone: regulates testosterone in men range of functions including sperm production, sexual desire, and controls the bone density, muscle size and strength, fat distribution, and production of red blood cells, and despite being a hormone masculine, but it plays a role in the regulation of sexual desire, bone density, muscle strength in women.
