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. "
An introduction to the process of homeostasis, a self-regulating process whereby equilibrium is achieved between various organs or segments of an organic system, such as the human body.
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 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 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 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 discusses two areas of anatomy physiology: (1) What the homeostatic value of flexor reflexes are and (2) Where olfactory receptors are located. The paper explains that the location of olfactory receptors is actually poorly suited to their job.
Abstract This paper examines elements of the integumentary system. The paper looks out how the system helps maintain homeostasis as well as first, second and third degree burns., why no cancers arise in the stratum corneum, and the effects of a reduced subcutaneous tissue layer in the newborn and the aged on temperature control.
From the Paper "You go to the beach to swim on an extremely hot sunshiny afternoon Describe two ways in which your integumentary system acts to preserve homeostasis during your outing The integumentary system preserves homeostasis in the body by regulating temperature and water loss on a hot day The body temperature is kept stable by the production of sweat which cools the body as it evaporates on the skin's surface The sweat glands can release between one and two liters of water per hour The Integumentary System

Abstract The paper discusses the molecular genetics of sickle cell anemia and how this disorder alters the red cell's function of homeostasis. The paper relates that the sickle cell gene is spread widely throughout Africa, the Middle East and India and countries in which there are large numbers of African immigrants, including the United States. The paper includes a map (as an appendix) that shows the regions of the world in which the sickle cell gene is most commonly found.
From the Paper "There are a number of hereditary anemias, which feature disorders of the structure or synthesis of hemoglobin, deficiencies of enzymes which provide energy to red blood cells or protect the red blood cells from damage, or abnormalities in the proteins found in the cell membranes of red blood cells. Inherited diseases of hemoglobin are the most important, and these are termed hemoglobinopathies; it is into this category that sickle cell anemia falls. Sickle cell anemia has a genetic basis, and was the first genetic disease to be characterized at the molecular level (Ingram, 2004"

From the Paper "The human body is an organized system, which consists of cells, tissues, organs and organ systems (Degen 2008). A cell is the basic unit of structure and function in every living thing or organism. It performs the basic functions to keep the organism alive. Most cells are microscopic. Each cell is covered by a cell membrane. Inside it is the nucleus, which controls and directs the cell's activities. It also contains all the information on the cell's characteristics. Cells form a tissue to perform the same function. The four basic types of tissue are muscle, nervous, connective and epithelial. Tissues, in turn, form an organ."
Abstract This paper examines how the heart supplies the entire body with blood and how cardiac failure is an acute emergency for the homeostasis of the body which will result in death. It covers the molecular and cellular events that cause heart faliure and aims to discuss the mechanisms by which the condition becomes symptomatic as well as explaining the principles behind the current treatments.
From the Paper "The loss of cardiac output will reduce the arterial blood pressure and will trigger a cascade of events similar to those seen during acute haemorrhage. The drop in blood pressure is detected by the baroceptors which increase their outflow to the sympathetic centre in the medulla oblongata. This causes an increased sympathetic drive. The increased sympathetic stimulation causes increased contractility of the cardiac myocytes to increase the blood pressure and cardiac output. Blood pressure is further protected by the action of the catecholamine released by the adrenal medulla causing vasoconstriction of the visceral organs via the action of alpha 1 adrenoceptors, protecting the supply to the brain and heart. There is also venoconstriction via the actions of the adrenoceptors causing an increase in the central venous pressure which compounds the increase caused by the cardiac failure."
Abstract This paper discusses and explains some basic anatomical features of the body such as the anatomical position, planes and sections through the human body, and homeostasis. Relation of anatomy to physiology.
From the Paper "The principle of complementarity was developed by Nils Bohr while working in the field of atomic physics, but can be applied to any science. It is an epistemological principle that essentially means that nothing can be studied in isolation, different aspects of the same organ can help us understand its true function in life. An organ's structure cannot be studied without understanding how it functions in the living system. Anatomy relates to physiology in that..."
Abstract This paper discusses the types of muscle tissue in the body and their functions. More specifically, the paper discusses the difference between the axial and appendicular skeletons, the difference between ligaments and tendons and the importance of bones in maintaining homeostasis.
From the Paper "The three main types of muscle tissue are skeletal, smooth and cardiac. The dark stripes or bands that are visible in muscle under the microscope are referred to as striations and they are responsible for the movement of muscles. Skeletal muscle is the muscle that can be seen and felt on the body-the muscles that are developed during a workout. This is the muscle in the arms, legs, back and abdomen among other sites. Skeletal muscle attaches to the skeleton in pairs one..."
Abstract This is a deep paper on genetics. The author delves into the scientific language of cell migration and organism development. Although apoptosis is an important mechanism in the development and homeostasis of many organisms, little is known about the mechanisms underlying apoptosis. Investigation into apoptotic genetics has yielded promising results, yet more research needs to be undertaken. This research may eventually yield insights into treatment of diseases linked to apoptosis, such as cancer and AIDS.
From the Paper "A developing organism undergoes many dramatic changes, including cell migration, proliferation and cell death. Apoptosis, a form of cell death, is characterised by nuclear condensation, plasma membrane alterations and the lack of an inflammatory response. Apoptosis is the fate of many cells in development and is necessary for normal development in a large number of organisms. The genes ced-3 and ced-4 regulate initiation of apoptosis in C. elegans. The mammalian homolog of ced-3, once thought to be Interleukin-1-Beta converting enzyme (ICE), is still under investigation. In C. elegans, ced-9 regulates genetic inhibition, while bcl-2 does the same in mammals."
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.."
