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 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..."

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."

From the Paper
"Hepatocytes
The hepatocytes are cells which comprise the liver parenchyma. They are its primary functional units. Each individual cell has the capacity for all functions. As a group, the hepatocytes perform a vast array of physiological tasks, all of which are necessary for the maintenance of biologic homeostasis.
In the normal adult liver, it has been estimated that there are about 250 billion hepatocytes (1:xxix). Indeed, the liver is the largest visceral organ in mammals; in man, its weight is approximately 1.5 kilograms (8:8).
The development of the liver parenchyma starts from entodermal cells. These embryonic precursors grow into the mesenchyma of the septum transversum (8:8). The organ itself generally performs two..."

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.."

Population Dynamics
Evolution
Conclusion
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"

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 paper explains that, for overweight people and people with type 2 diabetes mellitus, the low calorie and low fat diets recommended by the government do not work well and actually worsen the condition. The author points out that low carbohydrate diets, such as the popular "Dr. Atkins Diet", are synonymous with a high-fat and moderate protein regime. The paper relates that, when carbohydrate intake is restricted, the insulin levels decrease and the levels of glucagon increase. The author underscores that the increased fats and oils keep the appetite under control. The author suspects that the mechanism of insulin resistance is not a disease but rather a mechanism of homeostasis used to keep the body's fat to muscle ratio in balance. The paper states that, when the body is out of balance, type 2 diabetes mellitus occurs to correct the epigenetic factors that caused the imbalance.
From the Paper
"Insulin resistance and type 2 diabetes are now associated with decreased expression of genes that regulate oxidative phosphorylation in skeletal muscle. Uncoupling protein 3 (UPC3) is a protein transporter that uncouples oxidative phosphorylation of mitochondrial respiration in skeletal muscle. Studies on UCP3 functions under various physiological conditions have suggested that the function of UCP3 is not limited only to regulation of whole-body energy metabolism but is also involved in regulation of lipids metabolism. Uncoupling proteins act to convert stored fat into thermal energy."

From the Paper
"An oxygenated red blood cell enters the ascending aorta and passes into the descending aorta then into the left iliac artery to the left femoral artery finally arriving at the knee still in its oxygenated state. Once there, the oxygenated red blood cell travels into small arteries which supply blood to the knee and into arterioles which are even smaller arteries. These pass the oxygenated red blood cell along to the capillaries where the oxygen it is carrying along with nutrients..."
