The Workings Of The Endocrine System - 1183 Words

Introduction: Within field studies, the best way to understand the workings of the endocrine system usually involves injecting a specimen with a hormone or removing the gonads of the specimen to observe changes in hormone concentrations (Mazur, Booth, Dabbs, 1992). However with human subjects this kind of procedure proves to be rather unethical, and therefore researchers have found that the best way to observe a particular hormone, such as testosterone, is to observe what occurs when an individual is subjected to competition (Mazur et al., 1992). It has been observed that as an individual, male or female, participates in a competitive event, their testosterone levels are subject to rise (Booth, Shelley, Mazur, Tharp, Kittok, 1989). This notion is further supported through the observation of rising testosterone levels in those individuals who win their event. In fact it has been suggested that an individual’s testosterone level increases in order to maintain an aura of domina nce, and thus the act of winning a competition increases the level of testosterone in order to maintain that dominance and level of competitiveness over the game (Booth et al., 1989). While testosterone levels increase with victory, defeat often inspires the decrease of testosterone levels as well as feelings of competitiveness (Booth et al., 1989). This phenomenon is not limited to just those individuals competing in an event; in fact it has also been observed that even those watching a particularShow MoreRelatedThe Endocrine System Is Made Up Of Cells And Glands That1137 Words   |  5 Pages The endocrine system is made up of cells and glands that make hormones and release them into the blood. These hormones help to regulate reproduction, sleep, metabolism, cell growth, and development. The word endocrine is a derivative from two Greek words: â€Å"endo†, which means within or inside, and â€Å"krinis†, which is a verb for secrete. In the endocrine system, there are different glands that each excrete different hormones. All of these glands are ductless, and secrete their hormones straightRead MoreThe Glands of the Endocrine System Essay1480 Words   |  6 PagesThe Glands of the Endocrine System 5 The Glands of the Endocrine System The endocrine system is vital in maintaining homeostasis in the human body. Each gland of the endocrine system produces and releases hormones that enter the blood stream and travels to specific target organs. It is critical for this system to function properly in order to live a full life. The endocrine systems hormones are the chemical messengers that control many systems of the body. These messengers control metabolismRead MoreEndocrine Systems : The Endocrine System1170 Words   |  5 PagesEndocrine System Iesha Alexander, Racquel Shannon, Jerome Crumsey Richard Parker Dorsey School of Nursing BIO 102 Endocrine System The endocrine system is inclusive of the glands of the body and the hormones they secrete.

Ever wondered what it was made up of or how it helps with functioning our bodies? Well, the endocrine system is really important just as all the other systems in our bodies are important to us. The endocrine system is made up of multiple glands in our body that are used for the production and secretion of hormones into the blood stream. The endocrine system helps us in our growth and controlling the body s metabolic activity for everydayRead MoreEndocrine System And Endocr ine Systems1098 Words   |  5 PagesEndocrine System Paper The endocrine system is the accumulation of organs that create hormones that direct digestion system, development and advancement, tissue capacity, sexual capacity, generation, rest, and state of mind, in addition to other things.

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 located 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 MoreEssay on Bio lap report endocrine system1351 Words   |  6 Pages The Endocrine System Laszlo Vass, Ed.D.

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). So me body functions can be activated or inhibited by hormones,Read MoreQuiz on the CIPP Model of Evaluation755 Words   |  3 PagesCIPP MODEL OF EVALUATION Context, Input, Process, Product Overview of Model Useful model for evaluation of educational systems To be proactively viable, it must be used as a process for all stakeholders In general, requires that a series of questions be asked about four different elements of the model Model Concentration C I P P M ODE L Using CIPP to Evaluate Most could be used in combination: Class discussion, informal conversation Student interviews, evaluation forms Observation
