Abstract
This paper discusses the importance of homeostasis and epithelia in nursing, as well as the criteria used to classify the covering and lining epithelia. The paper also explains why maintaining a patient's homeostasis is one of the most important objectives in nursing.

From the Paper
"Homeostasis is important in nursing because the body mobilizes its fight-or-flight reaction in an attempt to maintain homeostasis. This can result in sweating, breathlessness, rapid heartbeat, shivering and trembling. The internal equilibrium of the body is the gauge of whether it is functioning properly or not. With homeostasis the body's systems are stable and self-perpetuating. Many of the tests that a nurse performs on a patient, such as taking a temperature or a blood pressure, are tests to determine whether the patient's body is in homeostasis or..."

Abstract
This paper examines how homeostasis is an important process in all organisms because it maintains the internal states of an organism despite what is happening outside of it and defends the organism from outside factors that may have a negative affect on its makeup. It looks at how there are many different forms of homeostasis and each of these forms has its own importance and how, when this process is disrupted, there are many negative repercussions which must be dealt with, as it can ruin an entire ecosystem, or end a human life.

From the Paper
"Homeostasis systems are generally ultra-stable, which means that it is able to test the variety of different ways in which its properties can be adjusted without doing harm to the organism. Also, their entire purpose contributes to the equilibrium of the organism in which it is present. This includes its internal, structural, and functional makeup. One thing that homeostasis does is regulate the amount of water and minerals inside the body of a mammal. This event, which occurs in the kidneys, is called osmoregulation and it is vital for the survival of a mammal. Homeostasis is also responsible for removing metabolic waste from the human body. This is known as excretion and is necessary for the human body to rid itself of excess materials. "

Abstract
This paper begins by explaining that homeostasis generally refers to the ability of an organism, including a human to maintain a certain state of equilibrium. The paper then goes on to discuss the subject of energy homeostasis with regard to human physiology and reviews some of the available literature on the subject. The paper explains that this research indicates that men and women may require different levels of basic nutrients in order to maintain a state of homeostasis and that water, like other nutrients, is a vital component for maintaining the physiology of the human body.

From the Paper
"Energy homeostasis can be defined as the state of equilibrium where the body is not only producing an adequate level of energy to function, but where the metabolism is working synergistically with the rest of the body to burn and store nutrients as needed (Cone, 2001). This is an ongoing process that occurs as human beings feed and hydrate themselves day in and out. Energy homeostasis is affected by a number of factors, including how much exercise and how much sleep one gets during the course of a given day (Cone, 2001). If for example a person sleeps excessively, in theory they will disrupt the natural state of equilibrium in the body, potentially causing even more sleepiness (contrary to what one might think, that an individual might feel more rested)."

Abstract
This paper explains the basic process of homeostasis, with a look at the crucial role it plays in the maintenance of the complex sequence of biochemical activities that occur within organisms. The paper also explains the functions of cell membranes in the process of homeostasis, different forms of homeostasis, and what happens when the process is disrupted.

From the Paper
"Homeostasis has also been formally defined by many scientists in different ways, perhaps most accurately as the "maintenance of a stable internal environment" whether in a cell or in the organism as a whole (MSNucleus, 2004). Homeostasis is in essence equivalent to a state of equilibrium. Much like balanced scales, homeostasis ensures that too much nor too little exists at any point in time within organisms. When a state of imbalance occurs, the scale tips unfavorably to one side or the other. Homeostasis works via establishment and maintenance of the internal chemical balance of cells, whether they are in a human life form or a botanical one. Homeostasis is crucial to maintenance of the complex sequence of biochemical activities that occur within organisms, traditionally during the process of energy utilization (MSNucleus, 2004)."

Abstract
This paper explains that disorders of homeostasis, fluid, and electrolyte balance occur in every setting, with every disorder, and with a variety of changes that affect healthy people. The paper also describes body fluids and electrolytes and the process of regulation of body fluid through osmosis. In addition, the paper discusses issues of homeostasis in the kidneys, skin, lungs, and the gastrointestinal tract.

From the Paper
"The hypothalamus manufactures ADH, which is stored in the posterior pituitary gland and released as needed. ADH is sometimes called the water-conserving hormone because it causes the body to retain water. Functions of ADH include maintaining the osmotic pressure of the cells by controlling the retention or excretion of water by the kidneys and by regulating blood volume.

Abstract
This paper defines homeostatis as the preservation of stability or constant condition in a biological system by means of automatic mechanisms that work against influences leaning towards disequilibrium. The author points out that, in human beings, many organs check homeostasis in the blood that gives fluid for all tissues; the kidney controls urea, pH and water concentration, the lungs control oxygen and carbon dioxide and the liver and the skin control temperature. The paper relates that homeostasis aids in discharge by eliminating injurious wastes from the organism: Lungs eliminate CO2 and water; blood vessels in the skin expand to let more heat to escape, sweat glands form sweat that pulls out heat from the body to evaporate it.

From the Paper
"For the existence of a cell, homeostasis is necessary and each cell provides as part of body system to homeostasis. Homeostasis relies on the body's incessantly working of many actions. Its main activities or functions are reacting to variation in the body's environment, exchanging materials between the environment and cells, metabolizing foods, and incorporating all of the body's miscellaneous activities. Over the years, the capacity of the body to do many of its functions changes slowly. Generally, the body performs its duties perfectly at both ends of life - in infancy and old age. At childhood, body works effectively and efficiently. At late maturity and old age the reverse is true. Slowly they become less and less able and operational."

Abstract
In this article, the writer reviews an article by Rampioni et al., entitled "RsaL provides quorum sensing homeostasis and functions as a global regulator of gene expression in Pseudomonas aeruginosa", regarding one of the most virulent and antibiotic resistant pathogens that is Pseudomonas aeruginosa. The writer maintains that the authors realize the importance of controlling this pathogen and have targeted quorum sensing as a primary first line defense in regulating this bacteria's virulent growth rate and debilitating effect in human beings. The writer discusses that the results of the study are certainly promising and they have opened up the understanding of quorum sensing activity in organism to greater levels and revealed even more complexity than previously thought. The writer concludes that this alone is enough to promote much further study into both quorum sensing and the activity of the molecule Rsal on that function.

From the Paper
"The authors realize the importance of controlling this pathogen and have targeted quorum sensing as a primary first line defense in regulating this bacteria's virulent growth rate and debilitating effect in human beings. Quorum sensing can be compared to a social behavior determinant which helps to regulate the overall population density of the bacterial community of Pseudomonas aeruginosa. In effect it is the controlling mechanism that senses the environment around the bacteria and starts or stops a population explosion of the pathogen. Finding the key chemical in the molecules of this genetic trigger is of primary concern tot he authors. Using Molecular microbiological techniques to control the gene expression may be far more effective that simple antibiotic treatments, which bacterial strains can become immune to over time in just a few generations of the population."

From the Paper
"A family is a complex natural social system complete with its own properties and processes. As in any system no part stands alone and no process operates without influencing, to a greater or lesser degree, every other process and every component of the system. Social Work assessments and interventions cannot, therefore, be based on the consideration of any individual or process in isolation. A review of four components of family systems--patterns of interaction, boundaries, rules, and homeostasis--demonstrates how these variables influence each other and how an understanding of these systemic interrelationships is crucial to those conducting Social Work assessments and designing interventions.

Family systems evolve rules, roles, and power structures as well as the various forms of communication, conflict resolution.."
