Homeostasis - Essay ExampleAs body needs to respond to any upset in the internal milieu very quickly therefore initial response of the body is a reflex response usually takes place finished peripheral controlling systems, especially sick system. Failure of homeostasis causes diseases disease and sometimes death.Major systems controlling homeostasis in the body are nervous system and endocrine gland system. These systems have got their own specific characteristics which make them integral components which help maintain homeostasisThere are some physiological set points related to various systems in the body. Whenever there is disturbance to these set points body responds to this variety and tries to bring the situation back to normal. This reversal of disturbance or change is necessary to keep an individual(a) vigorous and alive. Some of these conditions or parameters areCentral nervous system (CNS), autonomic nervous system (ANS) and endocrine systems work together to maintain these parameters at bottom normal limits. Any change in the set points is detected and recognized by these systems and expeditiously maintained by these systems with the help of feedback system. ... 6. Adrenal medulla epinephrin - 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 drive maintained around 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 parameter s 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 name of situations positive feedback also gets itself involved (Wikipedia 2007 Biology Online).All feedback systems work in a systematic and well organized way, the major components of a feedback systems areSensors signaling 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
