Abstract
When most individuals think of the digestive system, they think of those organs within the alimentary canal: the oral cavity, pharynx, esophagus, stomach, small intestine and large intestine. Organs that serve other purposes within the human body such as the gallbladder, liver and pancreas receive attention, but not in relation to their purpose as part of the accessory group of organs associated with the digestive tract. This paper presents a detailed discussion on these accessory organs limited to their purpose within the digestive tract.
From the Paper
"Imholtz (n.d.) tells us that accessory organs of the digestive tract are those that assist the digestive process but are organs of which no food passes through. Tamarkin (2006) comments that the major accessory organs such as the pancreas, gallbladder and liver have function other than those for digestion, but within the digestive system, they are considered exocrine glands that secrete fluids into ducts."

Abstract
This paper answers a number of questions relating to the human digestive system. The topics covered include the structure of the digestive system, its function and its physiology.
From the Paper
"The mucosa is the innermost lining of the digestive tract. In some regions the surface is folded to increase surface area. The mucosa contains different types of cells that secrete mucus digestive enzymes and hormones. Ducts from other glands penetrate the mucosa to open into the lumen. In the stomach and intestines the epithelium is simple columnar for secretion and absorption, but in the mouth and anus, where protection against abrasion, is required the epithelium is stratified squamous.

From the Paper
"A brief description of the structure of the stomach would help in gaining a better understanding of this important organ. The stomach is divided into four regions namely the Cardia, fundus, the body, and the pylorus. The stomach has two openings namely the cardiac orifice, which connects with the esophagus, and the pyloric orifice on its lower end, which leads to the duodenum. The fundus is the curved up area that extends above the cardiac orifice. The body or the intermediate region is the largest part of the stomach, which gradually leads to the pyloric portion that connects to the small intestine via the pyloric aperture. The stomach wall is composed of four different layers. The innermost layer is the mucosa. The mucosa is made up of gastric glands and gastric pits and secretes around 2 litres of gastric juice per day. This gastric juice is made up of HCL, protease (pepsin) and lipase. Parietal cells of the mucosa secrete hydrochloric acid. The goblet cells in the gastric pits that line the mucosa secrete mucus, producing the mucosal barrier that prevents the strong digestive acid from corroding the mucosa. [MSU]"

Abstract
Presented in a graph form, this paper provides great detail about the digestive systems of the smallest of creatures in the "kingdom animalia". It explains how lysosome produces a digestive enzyme to breakdown bigger molecules of fat, protein, and carbohydrates, into simple protein, monosaccharides and fatty acid to send to cytoplasm for the cell?s life, then converted into energy for cell growth.
From the Paper
"The higher phyla, starting from Cnidaria develops extracellular digestive system as well as it develops into radial body symmetry. Cnidarian possess incomplete gastrovascular cavity, tube-like digestive system in which water and other smaller organisms are transported in. Such organism like hydra has digestive layer called gastrodermis, which excretes digestive enzymes to assimilate food. This system is also adapted by Platyhelminthes, which also has similar gastrovascular cavity, mouth without anus."

The Small Intestine (Enzymatic Breakdown and Absorption)
Absorption of Nutrients
Absorption of Vitamins and Minerals
Conclusion
From the Paper
"The human digestive system is an intriguing mechanism involving different organs and enzymes in a complex mechanical and biochemical processes. Starting from the mouth and ending in the small intestine, the entire digestive mechanism is highly evolved and controlled by involuntary reflex actions that are triggered at every point by particular stimulus factors. While the stomach is the place where the main part of digestion begins, it is the small intestine where the final breakdown of respective ingredients occurs. The small intestine is also the region through which the finely broken down substances are absorbed back into the blood stream or the lymphatic system. The entire digestive process and the activities inside the alimentary canal offer an interesting peep into the amazing world of biochemical processes and cellular biomechanics."

Abstract
This paper examines the nervous and digestive systems of reptiles, emphasizing their main characteristics and briefly compare them to the nervous and digestive systems at other vertebrates including humans. The author points out that the anatomical characteristics of the reptile's nervous system, such as the position of the brain or the spinal cord, resemble closely those of the human and higher vertebrates; the reptilian nervous system has developed to provide the best adaptation of the reptiles' necessities, with emphasis on sight, smell and motor functions. The paper relates that birds and reptiles are the only vertebrates to have the cloacae chamber, the removal system of the body, is where the faeces is discharged; the urodaeum receives the urogenital tract ducts and the proctodaeum acts as a common collecting area prior to evacuation.
From the Paper
"As such, the reptilian nervous system is formed of two different components: the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system is composed of the brain and the spinal cord, while the peripheral nervous system is composed of all nervous tissues and structures that do not actually belong to the CNS. As at other vertebrates, the brain, constituent part of the central nervous system, is protected by the skull. The bones forming the skull similarly have names such as parietal and occipital, which also form the human skull, for example."

Abstract
Digestion consists of a physical and chemical breakdown of food. Because of the complexity and large size of the digestive system, diseases that can interfere with the body system are numerous and varied in their modes of transmission, their symptoms, their treatments, and their possible short-term and long-term effects. This paper focuses on three such diseases: Cirrhosis of the liver (caused by viral Hepatitis), hookworm disease (caused by hookworms), and cholera (caused by Vibrio cholerae). Each disease is examined in turn, its symptoms and its treatment. The diseases are summarized in a table at the end of the paper.
From the Paper
"The large size of the digestive system, along with the diverse group of organs associated with it; prevent the presentation of one specific defense mechanism against diseases. Depending on which organ the disease tends to focus on, the body reacts uniquely for that organ. However, the most definitive action taken against digestive system diseases are regulations and standards for living conditions. Many diseases that affect the digestive system relate directly to food, and undercooked food, mishandled food, and poor sanitation conditions are common factors in someone contracting a digestive system illness."

From the Paper
"One of the most fascinating developments made by the vertebrates was the heart. The complex and efficient four-chambered pumping mechanism possessed by mammals and birds evolved from what was only a muscular artery in protochordates. The heart itself is a specialized muscle responsible for circulating blood through the blood-vascular network. Marine protochordates possessed little more than a muscular region near the base of the aorta because, virtually anywhere on their bodies, they were capable of exchanging O2 and CO2 through their relatively thin skin. When scales and thicker skin emerged, however, this capability was lost, and respiration was localized in the pharyngeal region. An effective pumping device was required, and thus, the heart evolved."

Abstract
This paper examines the process of classification or division of a whole entity into numerous specific groups. It shows how dividing organizations, government, studies, written works and species of plants and animals into specific categories allows for more complete or focused attention to be applied to specifically functioning members within the given macrocosm. Special emphasis is placed on the classification of the human body into categories such as skeletal, muscular, endocrine, nervous, cardiovascular, lymphatic, respiratory, digestive, urinary and reproductive systems. Each system has a specific job, but all systems work together in order to keep the body alive and properly functioning. This paper shows how classification, separation and combined efforts of the human body has been used as the model after which societies, governments and their militia have been formed.
From the Paper
"Whether focus is upon a government structure, a company, a military structure or upon the individual human body, specific compartmental functions can be singled out and identified. Although no specific function can truly be described as being greater than another function, the overall entity will not be able to operate smoothly without the specific capabilities exerted by even the seemingly smallest of its divisions. The briefest of trips to a doctor?s office will reveal a cosmos within a cosmos that is so complex, various medical specialties have come about in order to treat the individual categories more completely."

Abstract
This paper discusses how rabbits have the same need as humans to produce energy in order to survive and how this energy production is directly related to the food the animal intakes. It looks at how the rabbit, oryctolagus cuniculus, obtains its nourishment from the foods it eats, which are mainly grasses, clovers, and sometimes even bark and how it then eats the droppings to get the maximum nourishment available from the food. The paper also discusses how this method is extremely different from how humans obtain the necessary nutrients to further endure life even though both species share the same internal process of cellular respiration necessary to exist and prevail.
From the Paper
"The mitochondria, which can be simply defined as a membrane-bound organelle located in all eukaryotic cells, is important for several reasons including its responsibility for the process of cellular respiration (Cellular). This process works through redox reactions, which is the term given to a chemical reaction in which at least one electron is transferred from one particular substance to another (Solomon 138). The importance of cellular respiration is apparent because of its resulting production of Adenosine triphosphate, which is commonly known as ATP. The ATP serves various purposes; however, the one most relevant to the nourishment of a rabbit would be the fact that it provides the energy which is used throughout the cells in several different activities. This fact results in the ATP being referred to as the energy currency of the cell (Solomon 125). "

"Animal Farm", 2004.
This paper discusses that the author's universal themes, digestible tone, and crafty use of language make George Orwell's novel, "Animal Farm", a great satirical and literary work.

Abstract
This paper explains that the basic plot of "Animal Farm" closely parallels that of the Russian Revolution: The animals on Manor Farm in Hertfordshire, England (the place of Orwell's birth) are dissatisfied with the negligent treatment they are receiving from Farmer Jones. The author points out that one major theme of this story is the sad, but often true, story of evil triumphing over the good: In the end, although the animals have fought and worked for their freedom, oppression reigns. The paper contends that Orwell is well-versed in the art of effective storytelling because Orwell's writing is simple yet descriptive and can be read and comprehended by the less advanced reader.
From the Paper
"Orwell?s language techniques continue in his careful name-choice for a number of the vital characters. Moses, the trained raven, represents the Church. He tells the animals about Sugarcandy Mountain where all animals go after death, delivering a religious message to the people just as his namesake did in the Bible. Napoleon, the great dictator pig, is named aptly after the French emperor, representing Stalin and Hitler in his totalitarian leadership. Squealer represents the newspapers and propagandists of the day who played spin doctor to report the news of the leaders in a palatable form that calms the masses, regardless of the truth of the events. A less obvious name choice is that of Frederick, who is named after Frederick the Great, who was strongly admired by Hitler."

From the Paper
"The typical representatives of the phylum Platyhelminthes, planarians, consist of small flatworms, are usually about 0.5 inches in length, and occur with gray or black coloring (1:382). The planarians are highly important to the student of biology, given their illustration of certain advances in the evolutionary process over the coelenterates. The planarian is abundant over the entire world in those spring-fed streams or cool, clear, permanent lakes and streams that are uncontaminated, in which they feed on small living or dead organisms. The planarians avoid light by clinging to the undersurfaces of stones or logs in the water.
The planarian differs from the hydra or a medusa in several ways (1:385). First, it has bilateral symmetry rather than ... "

Abstract
This paper details the effects that alcohol has on all body systems, including the brain, liver, heart and digestive track. Arguments for the moderation consumption of and abstinence from alcohol are presented, as well as information about alcoholism and its genetic cause. Next, the paper explains how alcohol is metabolized from the point of ingestion. Finally, the paper presents the long term cause of CDV, dementia, and diabetes. There are six figures to support the research, including charts of the chemical metabolization of alcohol, and the progressive effect of intoxication on body and behavior by BAC.
From the Paper
"There are three phases in the metabolism of alcohol: absorption, distribution and elimination. Absorption is the phase in which the greatest level of intoxication is experienced, a state that may be quantified by assessing blood alcohol content (BAC). At any point in metabolism, a drinker's blood alcohol content measures grams of ethanol per 100 milliliters of blood. However, since metabolic rate varies in different individuals, BAC is not necessarily a direct indication of how many drinks were consumed. Instead, BAC is influenced by such factors as the amount of food in the stomach, sex, and body weight and composition. Generally speaking, females have a lower body weight and higher percentage of body fat, making them more sensitive to alcohol. "
