The phenomenon of homeostasis is understood as the ability the body has to stabilise its internal environment despite the ever changing external conditions (waterhouse, 2007) this internal environment is an atmosphere which surrounds the cells and is therefore the medium in which the cells are in direct contact with in the body (sherwood, 2001. Best answer: homeostasis is the process used by the body to maintain a stable internal environment either negative feedback or positive feedback can be used in homeostasis in negative feedback, the body changes an internal condition back to its normal state this is the most common way that the body regulates itself. In its standard format, the concept of homeostasis refers to the ability, present in all living organisms, of continuously maintaining certain functional variables within a range of values compatible with survival. Homeostasis is the ability of an organism to maintain a stable, constant internal environment, even when the external environment changes humans maintain homeostasis in processes such as controlling temperature, blood pressure and respiration as well as maintaining a balance in ph and electrolytes. Of, pertaining to, or relating to homeostasis supplement homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes it is involved in the maintenance of the constant internal environment which includes the function of kidney, liver, skin, etc.
This article, the first in a series of four, looks at the anatomy and physiology of homeostasis homeostasis - part 1: anatomy and physiology 4 april, 2006 this article, the first in a series of four, looks at the anatomy and physiology of homeostasis. Homeostasis is the term used to describe the internal stability needed for survival of an organism, including humans and animals this is a narrow scope of conditions within the living creature, such as temperature and ph balance, and it is separate from the external environment. Helpful, trusted answers from doctors: dr teimouri on homeostasis medical definition: homeostasis refers to a stable or balanced state helpful, trusted answers from doctors: dr teimouri on homeostasis medical definition: homeostasis refers to a stable or balanced state. Homeostasis is the physiological consistency of the body despite external fluctuations all complex multicellular organisms maintain a stable internal environment using their organ systems.
Homeostasis: homeostasis, any self-regulating process by which biological systems tend to maintain stability the stability attained represents a dynamic equilibrium, in which continuous change occurs yet relatively uniform conditions prevail learn more about the characteristics and functions of homeostasis. Hi, in order to write a good essay about negative feedback of homeostasis, first you should start your essay by defining homeostasis then, explain the two types of homeostasis talk briefly about positive feedback, and then mention that this essay is about the negative feedback. A) discuss the importance of homeostasis in mammals and explain the principles of homeostasis in terms of internal and external stimuli, receptors, central control, co-ordination systems, effectors (muscles and glands. However, the universal use and attribution of a control mechanism based exclusively on negative feedback have raised objections to the term homeostasis (eg, berridge 2004 sterling 2012) it is not our intent to review and discuss here the foundations of the many objections raised about homeostasis. Discuss the term homeostasis with reference to a named physiological system relate your answer to the lower limb essay the phenomenon of homeostasis is understood as the ability the body has to stabilise its internal environment despite the ever changing external conditions (waterhouse, 2007.
Gcide (300 / 7 votes) rate this definition: homeostasis (n) the ability and tendency of certain systems to maintain a relatively constant internal state in spite of changes in external conditions this ability is achieved by the presence of feedback mechanisms which can adjust the state of the system to compensate for changes in the state caused by the external environment. The biological definition of homeostasis is “the tendency of an organism or cell to regulate its internal environment and maintain equilibrium, usually by a system of feedback controls, so as to stabilize health and functioning. Homeostasis, from the greek words for “same” and “steady,” refers to any process that living things use to actively maintain fairly stable conditions necessary for survival the term was coined in 1930 by the physician walter cannon. Walter bradford cannon (october 19, 1871 – october 1, 1945) was an american physiologist, professor and chairman of the department of physiology at harvard medical school he coined the term fight or flight response , and he expanded on claude bernard 's concept of homeostasis.
Quick reference n the physiological process by which the internal systems of the body (eg blood pressure, body temperature, acid-base balance) are maintained at equilibrium, despite variations in the external conditions — homeostatic adj. Homeostasis - elaine’s reaction to the high winds and extreme cold is because of her body maintaining homeostasis homeostasis is the ability of the human body to maintain its internal environment at equilibrium, or in other terms, to keep the body at a constant temperature. Homeostasis is defined as a constant, steady environment despite external changes, such as exercise exercise affects your body temperature, blood oxygen levels, sugar levels and hydration – all properties necessary for your survival. Published: mon, 04 dec 2017 the aim of this essay below is to explain homeostasis, the principles involves, the negative feedback, the control of the blood glucose level, the mechanism of temperature regulation and the structure of the kidney and the function and the hormonal control of osmoregulation. This article provides an overview of homeostasis and stress, the main effectors and targets of the stress response, and the effects of stress on the organism box 1 history of stress the term.
The term homeostasis can be broken down into roots for better understanding homeo means similar and stasis, a derivative of static, refers to the act of standing still put together in terms of the body, this word describes a steady rhythm of orderly function. Definition of homeostasis in the audioenglishorg dictionary meaning of homeostasis what does homeostasis mean proper usage and pronunciation (in phonetic transcription) of the word homeostasis information about homeostasis in the audioenglishorg dictionary, synonyms and antonyms. Homeostasis, homoeostasis / ˌhəʊmɪəʊˈsteɪsɪs / n the maintenance of metabolic equilibrium within an animal by a tendency to compensate for disrupting changes the maintenance of equilibrium within a social group, person, etc. Homeostasis definition, the tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function see more.
