Essay about The Endocrine System - 1431 Words

The endocrine system is a group of glands distributed throughout the human body. This group of glands secretes substances called hormones. These hormones discharge into the bloodstream (Shier, Butler Lewis, 2009). The endocrine system does not have a single anatomic location. It is dispersed throughout the human body. The final purpose of this system is to control, regulate, and coà ¶rdinate the functioning of the human body (p.291). Some body functions can be activated or inhibited by hormones, which are secreted in very small quantities. Hormone related diseases may be due to hyper secretion or hypo secretion. The hormones secreted by the endocrine glands regulate the growth, development and function of many tissues, and coà ¶rdinate the†¦show more content†¦Hyperthyroidism may result in exopthalmia (The eyes protrude) (p. 301). The parathyroid glands are in front of the base of the neck around the thyroid gland and secrete parathyroid hormones. The parathyroid hormone regulates blood levels of calcium and phosphorus (p. 301). The parathyroid hormone affects the bones, kidneys, and intestines (Shier et al., 2009).Adrenal glands are endocrine glands that sit atop the kidneys (Shier et al., 2009). The adrenal glands secrete hormones that increase the heart rate, breathing rate, the force of cardiac muscle contraction and elevates blood pressure and blood glucose level. This activity prepares the body for energy expending action, sometimes called fight or flight responses (Shier et al., 2009).According to Shier, Butler and Lewis (2009), â€Å"other glands that produce hormones and thus are parts of the endocrine system include the pineal gland and the thymus gland†(p. 307). These authors also argued that the pineal gland, located deep between the cerebral hemispheres, secretes the hormone melatonin that acts on certain brain regions and functions as a biological clock. The changing levels of melatonin across 24 hours enable the body to know wh en it is daytime or nighttime.Shier, Butler and Lewis (2009) explain that the thymus gland, in the anterior superior mediastinum, secretes hormones called thymosins that play an important role in immunity. The thymus is related to the production of lymphocytes.

The Endocrine System consists of many components but is made up of Endocrine glands which have no ducts and usually secrete their hormones directly into the tissue fluid. It also contains many tissues that secrete hormones. The glands of the Endocrine system are located throughout the body but are mostly central to the body. The system has manyRead MoreEndocrine Systems And The Endocrine System1155 Words   |  5 Pagesdiverse systems in the body, the endocrine system is much of the time overlooked and is easily confused with the excretory system. The endocrine system works with the nervous system in order to maintain homeostasis in the body. Independently the endocrine system is a small group of glands l ocated throughout the body, which include the pineal, adrenal, and thymus glands. Each gland in the endocrine system produces, stores, and releases hormones so when working properly the endocrine system plays anRead MoreEndocrine Systems : Hormones And The Endocrine System1390 Words   |  6 PagesEndocrine System:†¨ Hormones are chemical substances that act as messengers in the body. They are produced in endocrine glands scattered throughout the body. Together all these glands form the endocrine system.†¨Ã¢â‚¬ ¨The endocrine system is coordinated by the pituitary gland, which responds to information from the hypothalamus. The hypothalamus is a portion of the brain and is made of nervous tissue. It constantly checks the internal environment — that is, the conditions within the tissues, organs andRead MoreThe Endocrine System1467 Words   |  6 Pagesof the pituitary gland secrete various hormones for various functions.

One of the major systems we need is the endocrine system. The endocrine system is the collection of glands of an organism which secrete hormones directly into the circulatory system, which then distributes the hormones to specific organs. The main endocrine glands include the hypothalamus, pituitary gland, pineal gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, gonads(testes, ovaries) and thymus.
