Endocrine systems, also referred to as hormone systems, are found in all mammals, birds, fish, and many other types of living organisms. They are made up of:. Hormones act as chemical messengers that are released into the blood stream to act on an organ in another part of the body. Although hormones reach all parts of the body, only target cells with compatible receptors are equipped to respond. Over 50 hormones have been identified in humans and other vertebrates. Hormones control or regulate many biological processes and are often produced in exceptionally low amounts within the body.

Human endocrine system

Growth hormone GH stimulates the growth of bone and other tissues in the human body. The hypothalamus is very important in the release of GH through the release of growth-hormone-releasing hormone GHRH , which causes release of GH from another endocrine gland. The posterior pituitary is responsible for antidiuretic hormone ADH and oxytocin release. The thyroid releases thyroid hormones T3 and T4 , which control metabolic rates. The pancreas releases glucagon and insulin to control blood sugar levels.

Numerous body functions in humans and animals are controlled by messenger substances such as hormones. This system of hormones is perfectly balanced and, in conjunction with hormonopoietic glands, it makes up what is called the endocrine system. The term endocrine disruptors refers to substances that could have adverse health effects by disturbing the endocrine system once they would enter the body at an effective dose. Endocrine disruptors can occur naturally phytohormones or are being produced artificially synthetic.
