Functions Of The Endocrine System

The structure and function of the Endocrine system

I will be discussing about the structure and function of the Endocrine system and ......

The endocrine system is the collection of glands of an organism that secretes hormones into circulation system and carried to target organs. The major organs include the pineal gland, pituitary gland pancreas, ovaries, testes, thyroid, thyroid gland, parathyroid glands and adrenal gland.

The endocrine system uses chemical signals called hormones which carry information from one part of the body to a distant part of the body. Hormones are released from the endocrine cell into the extracellular environment, which then travel in the

The endocrine system, on the other hand, takes substantially longer for hormones to move their way from the gland that produces them, through the bloodstream, and ultimately to the organ or cells where they take effect. In addition, the actions of hormones are much longer lasting than the milliseconds of nerve impulses. (Margaret Baker 2007) Another way of putting this is to say that the nervous system directs the body's short-term responses, whereas the endocrine system directs the body's longer-term responses. One other point to note is that both systems are mutually controlled. For example, when the nervous system needs to control things longer term, it acts through the endocrine system by stimulating the release or reticence of hormones themselves from the endocrine organs. On the other hand, adrenalin, released by the adrenal glands, acts upon the brain to stimulate the fight response there are several similarities between neurons and the endocrine. Both secrete chemicals that are used for communication for regulating and maintaining homeostasis. (David Wayne
