blood remains stable? These things and many more are maintained as part of a process called homeostasis. Homeostasis is the body’s maintenance of a stable internal environment‚ and depending on what particular aspect of the body’s physiology you are talking about there are corresponding systems to maintain this normal‚ stable range. The body maintains homeostasis through a self regulating control system‚ or "homeostatic mechanism" (Shier) if you will. All of these homeostatic

Achieving homeostasis‚ or equilibrium‚ is the end goal of many of the processes of the regulatory systems in the human body. The human body is a machine of sorts‚ operating through various multifaceted‚ multifunctioning systems to continue its life‚ which is done optimally while operating at homeostasis. To do this‚ it either creates positive or negative feedback loops until it reaches what it believes to be the most efficient setting. A negative feedback loop is one of the body’s regulatory functions

HOMEOSTASIS Homeostasis is an internal environment that is regulated in order to remain in a stable and constant state. To be able to maintain homeostasis‚ the homeostatic control system shows how communication within the body is important in homeostasis‚ there are four main components to this system: the stimulus (change)‚ the receptor (detects the change)‚ the control centre (receives the information) and the effector ( produces the response). The stimulus in this case would be the change in

The nervous system helps maintain homeostasis Homeostatic control mechanisms have at least three interdependent components: a receptor‚ integrating center‚ and effector. The receptor senses environmental stimuli‚ sending the information to the integrating center. The integrating center‚ generally a region of the brain called the hypothalamus‚ signals an effector (e.g. muscles or an organ) to respond to the stimuli. Positive feedback enhances or accelerates output created by an activated stimulus

equilibrium‚ or homeostasis‚ which is constantly challenged by internal or external adverse effects‚ termed stressors.[4‚5] Thus‚ stress is defined as a state in which homeostasis is actually threatened or perceived to be so; homeostasis is re-established by a complex repertoire of behavioral and physiological adaptive responses of the organism Our biological stress response was designed for survival and is regulated by both the neural and endocrine (hormonal) systems. Fundamentally‚ both systems are communication

Urinary tract infections refer to the presence of pathogenic microorganisms within the urinary tract and its classification is usually done on the basis of infection sites:-bladder [cystitis]‚ kidney [pyelonephritis]‚ or urine [bacteriuria] and also can be asymptomatic or symptomatic (Quigley R 2009‚ Schlager TA2001). They are among the most commonly acquired bacterial infections and they account for an estimated 25-40% of the nosocomial infections (Bagshaw SM‚ Laupland KB 2006). Urinary tract infection
