Homeostasis - Essay ExampleAs body necessarily to respond to any misgiving in the internal milieu very quickly therefore sign response of the body is a reflex response usually takes place through peripheral tyrannical remainss, especially restless form. Failure of homeostasis causes diseases disease and sometimes death.Major systems controlling homeostasis in the body atomic number 18 nervous system and hormone system. These systems have got their own specific characteristics which make them integral components which care assign homeostasis in that respect are some physiological jell points related to various systems in the body. Whenever there is overturnance to these set points body responds to this convert and tries to bring the situation back to average. This reversal of disturbance or change is unavoidable to keep an individual healthy and alive. Some of these conditions or parameters areCentral nervous system (CNS), autonomic nervous system (ANS) and endocrine s ystems work together to maintain these parameters within normal limits. whatsoever change in the set points is detected and recognized by these systems and efficiently maintained by these systems with the help of feedback system. ... 6. Adrenal medulla adrenaline - adaptation to stress7. Pancreas insulin - regulation of blood glucose level.Physiological set pointsThere are some physiological set points related to various systems in the body. Whenever there is disturbance to these set points body responds to this change and tries to bring the situation back to normal. This reversal of disturbance or change is necessary to keep an individual healthy and alive. Some of these conditions or parameters are Body temperature regulated close to 37 C Blood pH kept at 7.4 Arterial blood pressure maintained nearly 120/80 mm HgMaintenance of blood glucose levelMaintenance of fluids and salts, osmoregulationCentral nervous system (CNS), autonomic nervous system (ANS) and endocrine systems work together to maintain these parameters within normal limits. Any change in the set points is detected and recognized by these systems and efficiently maintained by these systems with the help of feedback system. Initially, most of the time, nervous control takes this initiative of maintaining homeostasis o short term basis afterwards, endocrine system takes the responsibility of responding change in the internal milieu. Homeostatic system functions following the feedback mechanisms. Although, negative feedback system is utilized most of the time but in a limited number of situations positive feedback likewise gets itself involved (Wikipedia 2007 Biology Online).All feedback systems work in a systematic and well organized way, the major(ip) components of a feedback systems areSensorsSignal transmittersControl center and Effectors. Sensors are directly involved in the situation, which disturb the internal environment of the body they relay signals to the central
