Endocrine systems, also referred to as hormone systems, are found in all mammals, birds, fish, and also many other species of life organisms. They are made up of:

Glands situated throughout the body;Hormones that space made by the glands and also released right into the bloodstream or the liquid surrounding cells; andReceptors in various organs and tissues that recognize and also respond to the hormones.

Why room Hormones Important?

Hormones act as chemical messengers that are released right into the blood stream to act ~ above an body organ in another component of the body. Return hormones reach all components of the body, just target cells v compatible receptors room equipped to respond. End 50 hormones have been determined in humans and also other vertebrates.

Hormones control or manage many biological processes and are often created in exceptionally low amounts within the body. Examples of such procedures include:

blood sugar control (insulin);differentiation, growth, and function of reproductive guts (testosterone (T) and estradiol); andbody growth and energy production (growth hormone and thyroid hormone).

Much favor a lock and key, many hormones act by binding come receptors the are created within cells. When a hormone binds to a receptor, the receptor carries the end the hormone"s instructions, one of two people by transforming the cell"s existing proteins or transforming on genes that will develop a brand-new protein. The hormone-receptor complex switches ~ above or switches off specific biological processes in cells, tissues, and organs.

Some examples of hormone include:

Estrogens room the group of hormones responsible because that female sexual development. Lock are created primarily by the ovaries and in little amounts by the adrenal glands.Androgens space responsible for masculine sex characteristics. Testosterone, the sex hormone created by the testicles, is one androgen.The thyroid gland secretes two key hormones, thyroxine and also triiodothyronine, into the bloodstream. These thyroid hormone stimulate all the cell in the body and also control organic processes such together growth, reproduction, development, and metabolism.

The endocrine system, made up of all the body"s various hormones, regulates all biological processes in the body from conception through adulthood and also into old age, including the development of the mind and worried system, the growth and function of the reproductive system, and the metabolism and also blood street levels. The female ovaries, male testes, and also pituitary, thyroid, and also adrenal glands are significant constituents that the endocrine system.

Where are Endocrine Glands situated in the human being Body?


Hypothalamus - The hypothalamus web links our endocrine and nervous systems together. The hypothalamus drives the endocrine system.

Pituitary gland - The pituitary gland receives signal from the hypothalamus. This gland has actually two lobes, the posterior and also anterior lobes. The posterior lobe secretes hormone that room made by the hypothalamus. The anterior lobe produces its own hormones, numerous of which act on other endocrine glands.

Thyroid gland - The thyroid gland is crucial to the healthy advancement and maturation of vertebrates and regulates metabolism.

Adrenal glands - The adrenal gland is comprised of two glands: the cortex and also medulla. These glands produce hormones in response to stress and also regulate blood pressure, glucose metabolism, and the body"s salt and water balance.

Pancreas - The kidneys is responsible for developing glucagon and also insulin. Both hormones assist regulate the concentration of glucose (sugar) in the blood.

Gonads - The male reproductive gonads, or testes, and female reproductive gonads, or ovaries, produce steroids that affect growth and advance and also regulate reproductive cycles and also behaviors. The major categories of gonadal steroids room androgens, estrogens, and progestins, all of which are uncovered in both males and females yet at various levels.

How can Chemicals impact the Endocrine System?

Scientific study on person epidemiology, activities animals, and also fish and also wildlife suggests that eco-friendly contaminants have the right to disrupt the endocrine system causing adverse-health consequences. That is important to get a far better understanding that what concentration of chemicals found in the environment may cause an adverse effect. Various varieties of clinical studies (epidemiology, mammalian toxicology, and also ecological toxicology) are crucial to resolve numerous of the scientific questions and also uncertainty surrounding the endocrine disruptor issue. Many such research studies are at this time underway by federal government agencies, industry, and academia.
