¶ … body and the function of Homeostasis
Define the process of homeostasis, then list and explain five homeostatic functions that our bodies perform.
According to Steve Nakoneshny, who quotes a definition from Thibodeau & Patton, homeostasis can be defined as "the relative constancy of the normal body's internal environment."
However, this definition is somewhat incomplete and we should mention the fact that homeostasis, even if generally used when referring to the human body, can also be applied to nature. In this case, it is referred to as ecological homeostasis. Second of all, we should reassert the fact that homeostasis is a condition and not a process, even if it is generally associated with the action.
In order to briefly explain the definition, we should remember the fact that, as any system, the human body has certain parameters between which it functions best....
Function of Homeostasis in Human Biology The preservation of stability or constant condition in a biological system by means of automatic mechanisms that work against influences leaning towards disequilibria is Homeostasis. (Homeostasis {hohm-ee-oh-stay'-sis}) Homeostasis is the capacity of the body to preserve relative constancy and work even when severe changes occur in the external environment or in one part of the body. (Homeostasis: Toxiocology Tutor III) This is one of the
Homeostasis can be maintained as long as there are no long-term changes in the physiological factors that directly influence it. A settling point is established when there is a balance between opposing forces. These points are capable of change and are likely to do so when the opposing forces alter their balance (Berridge, 2004). The drive reduction theory also addresses the motivational drives to maintain homeostatic regulation. In this theory,
Homeostasis Defined Homeostasis, according to Nirmalan and Nirmalan (2017), is the propensity for living organisms to maintain relative stability in the internal environment. Homeostasis is made possible through the cooperation of several regulatory mechanisms and separate sub-systems which make up the normal physiology of a living organism (Nirmalan & Nirmalan, 2017). During critical illnesses internal or external stress can make an attempt at interfering with the self-regulation systems beyond what is
The central nervous system is responsible for interpreting the signals sent by these organs, which are meant to reflect energy stores, the recent nutritional status of a person and other factors related to energy metabolism. Further the authors point out that parts of the central nervous system including sections of the hypothalamus then coordinate energy intake and expenditure. The authors suggest that manipulation of any of these components may
D.). The primary organ that is accountable for regulating metabolism is the hypothalamus. The hypothalamus is situated on the brain stem and forms the floor and part of the lateral walls of the third ventricle of the cerebrum. The main functions of the hypothalamus is to control and integrate activities of the autonomic nervous system (ANS), production and regulation of feelings of rage and aggression, regulation of body temperature and regulation
The circulatory or cardiovascular system is responsible for moving nutrients, wastes and gases between body cells, transporting blood across the whole body and battling disease (Circulatory System). Its principal elements are the heart, numerous blood vessels, and blood. The heart forms the circulatory system's core. This 2-sided, 4-chambered pump which distributes blood to various arteries comprises of the right and left ventricles, and right and left atria. The ventricles, situated within
