Introduction
The endocrine system is a collaboration of all the glands in the human body and all the hormones produced by those glands1. The glands are controlled by the stimulation of the human nervous system including the chemical receptors in the blood and the hormones produced by other glands. By regulating and controlling the hormone levels in the body the endocrine system controls homeostasis in the body1. The gland system can be divided into two types. Exocrine glands release secretions outside of the bloodstream, mainly to the skin and the mouth. Meanwhile, endocrine glands release secretions into the bloodstream where they are transported elsewhere2.

Homeostasis
Homeostasis is a very important part in the survival of the human being. Homeostasis is responsible for the balance of the internal systems. It helps regulate body temperature and maintains equilibrium between alkaline and acidity4. Hormones released by glands in the body, signal other glands to perform tasks in order to maintain homeostasis. Glands like the pancreas release hormones like insulin and glucagon into the body to signal the body to start storing or releasing sugars. If the pancreas were to fail the body would not be able to recognize when it needs to store or release sugars. This failure to function destabilizes homeostasis in the body3-4. The loss of the pancreas function is lethal and is unrecoverable. As seen in figure 1 the endocrine system is a collection of glands each designed for a specific function. In order to maintain equilibrium in the body all the glands must work together.

Hormones
Hormones are very important to the body; they serve as a communication device between glands, tissues and organs3. Hormones regulate a variety of physiolog...

...he production of estrogen and regulate hormones for reproduction. The pancreas is responsible for the regulation of sugar levels in the body. It releases insulin and glucagon each specialized in telling the body to store or use sugars. The suprarenal and adrenal glands are responsible for how energy is stored and how it’s used. The testes are responsible for the creation of sperm and the testosterone. Testosterone is the male sex hormone that promotes puberty and furthers growth3.

Essay On The Endocrine System

- The Endocrine System Victor Garcia, SVN Med Surg I VNSG 1329 Coastal Bend College, Vocational Nursing November 20, 2017 The Endocrine System Introduction There are two main communication systems in the human body. The first is the nervous system which regulates body functions and reacts to stimuli through electrical impulses. The second system is the endocrine system. The endocrine system is made up of several glands that are distributed throughout the body. The endocrine system communicates with the rest of the body through the use of hormones....   [tags: Endocrine system, Glands, Endocrine gland]

- Jennifer Mauro & Henna Assifi Mrs. Panah Anatomy 17 October 2017 Endocrine System There are many organ systems involved in allowing the human body to function properly. A very important one is the endocrine system, which is made up of glands that produce and secrete hormones into the bloodstream. These hormones are a chemical communication system that transfers information between cells that regulate different functions of the body. These functions include metabolism, growth, and sexual development and function....   [tags: Endocrine system, Endocrine gland, Glands, Thyroid]

The Function Of The Endocrine System Essay

- Endocrine system, together with nervous system, is responsible for transmitting information around the body. The hormone is a chemical, composed of specialised cells, which released to the bloodstream becomes a chemical messenger. Communication occurs in two types. First of all, two endocrine glands have impact on each other. Secretion from one gland, stimulates secretion of another hormone by other gland. For example, pituitary gland, located in hypothalamus, stimulates adrenocorticotropic hormone stimulating the production of cortisol in adrenal glands....   [tags: Endocrine system, Pancreas, Metabolism]

Essay On The Endocrine System

- Endocrine essay The endocrine system is a group of glands that create hormones in our bodies which help regulate growth and development, metabolism, sleep and mood as well as many others. The endocrine system secretes hormones internally through our blood stream. The endocrine system has a network of glands that work together to produce hormones and here is am example of some that may be small or have a small role in the endocrine system but are extremely important. The glands of the endocrine system are: hypothalamus, pineal, pituitary, thyroid, parathyroid, pancreas, adrenal, thymus and the female glands ovaries and the male glands the testes....   [tags: Thyroid, Endocrine system, Hyperthyroidism]

The Function Of The Endocrine System Essay

- 1. The general function of the endocrine system is gland based to produce hormones that help with metabolism, growth, tissues, and reproduction. The structure between the nervous system and endocrine system are very similar the basics of both systems involve triggering glands throughout the body from receptors. The function on the other hand is a little different because the nervous system makes a fast response through specific glands and muscles. While the endocrine system is more widespread it also works at a slower pace....   [tags: Hypothalamus, Endocrine system, Pituitary gland]

Essay On Endocrine System

- The Endocrine system is a collection of glands within the body that secretes and regulates hormones for the body. Endocrine system is composed of the pituitary glands, thyroid glands, parathyroid glands, and adrenal glands, pancreas, and ovaries/testicles. The Endocrine system is crucial to the human body as it works with the Nervous System, to provide proper regulation in metabolism, growth and development, sexual and reproductive functions, and sleep. Sadly, the Endocrine system is quite fragile, and can be manipulated by multiple chemicals that can cause harm to the body....   [tags: Endocrine system, Thyroid, Cosmetics, Glands]

Exocrine (exit) glands such as the stomach, uterus, nasal, and ear canal all secrete products into the duct and exit through sweat, oil, and saliva or as mentioned earlier, the digestive glands. Endocrine glands secrete into the blood circulation, there are no ducts involved in the secretion of endocrine glands.

The Endocrine System And Central Nervous System Essay

-   Introduction Like a detective who examines criminality, a physician analyzes and identifies illnesses. Most people are unaware of the similarities in symptoms of most diseases, which is why it is important to see a specialist to properly diagnosis any medical conditions. For instance, endocrine system (ES) disorders and central-nervous system disorders display psychological symptoms that most regular civilians would consider to be psychological disorders, such as anxiety or mood swings. However, it is crucial to recognize that a disruption in the functions of both the endocrine system and central nervous system can generate mental disorder-like symptoms, thus it is worth noting the roles...   [tags: Nervous system, Brain, Endocrine system]

Essay on Endocrine Disruption

- The endocrine system is very dynamic and has ties to most, if not all of the other major systems of the body. It is responsible for production of hormones and the regulation of them as well. These hormones act as chemical messengers within the body. Through several differing mechanisms, they are able to trigger very specific responses in target cells or organs. This is what enables the endocrine system to guide growth, development, reproduction, and behavior, among many others as well. The hormones produced from the endocrine system come from a wide range of different places....   [tags: The Endocrine System]
