What Is The Digestive System - Free Essay Example

  What is the digestive system people ask? To me the digestive system is fascinating and it has really interests me. The digestive system involves the breakdown if food into liquids. It is known as the GI tract. The digestive system is important because your body needs nutrients from the food to stay healthy. The system breaks down the nutrients from the food you eat to small components to store energy, help you grow, and repair any broken down parts.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Proteins are turned into amino acids, fats break are turned fatty acids and glycerol, and carbohydrates broken down into simple sugars. Each part of the digestive system helps move and break down food into smaller parts. Once the food is broken down into smaller parts, the nutrients can be removed from the mixtures and used for the body. There are many different parts to the system including, mouth, esophagus, stomach, pancrea, liver, gallbladder, small intestine, and large intestine. All of these elements work together transporting your food throughout the GI tract to complete the process of breaking down food.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   First the food goes to your mouth which chews the food. The salivary glands in your mouth make saliva which moistens your food so it can easily move down your esophagus. After you swallow, peristalsis pushes down the food you swallowed through the esophagus into your stomach. In your stomach there is an acid called gastric juice that breaks down the food. The strong muscles in your stomach mix food with the gastric juice that helps break down the food to make it chyme, the chyme then is transferred to your small intestine. The pancreas makes a digestive juice that contains enzymes that break down carbs, fats, and proteins. The then pancreas delivers juice to the small intestine through tubes called ducts.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The liver makes another juice that is called bile. Bile helps absorb fats and break down some vitamins. The liver then transports the mixture to the gallbladder for storage is not used, or the small intestine for use. The gallbladder is used to store bile from the liver between meals. When you eat, the gallbladder delivers the mixtures into the small intestine for use. The small intestines mixture contains bile and pancreatic juice to complete breakdown of food. It moves water from the bloodstream to help break down. It also absorbs water for other nutrients and for the use of the food. Then the food goes to the large intestine. The bacteria helps break down remaining nutrients. Parts that are still not used, go to waste.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   As you can see the digestive system is very complex and the food you eat goes through a lot to get all the nutrients and vitamins out if it to become useful for the body. It is truly fascinating to see what it has to go through to become useful for the body.   When I was in 7th grade I first learned about the body and that bugun my interest. I really became very interested when my teacher was talking about the digestive system, it really caught my attention about how the body works.

Essay on Personal Education Goals - 1093 Words

The path I have taken toward obtaining my Bachelor of Science Degree in Business, Management, and Economics, with a concentration in Marketing, has been different than I expected when I first started college. I started at Brooklyn College at 17-years-old and frankly, I wasn’t ready for it. I struggled to balance an awkward schedule of classes and inconsistent study habits. I never felt completely comfortable there and after two years of performing poorly, I enrolled at Kingsborough Community College. I viewed it as a new start and seized the opportunity. I decided to major in Business Administration; I made the Dean’s List, and saw my grades improve dramatically. After completing 74 total credits, I decided I was ready to return to a†¦show more content†¦This brings me to today. Enrolling in Empire State College is one of the best decisions I have made in quite some time. The Center for Distance Learning program is exactly what I have been looking for the past few years. I’m sure it is said frequently, but the administration and faculty at Empire State College are second to none. As many others in the country, I was laid-off in the past year. I currently make a living doing sporadic part-time work whenever it becomes available. This is the reason I did not look to go back to the College of Staten Island, as I would be forced to miss classes from time to time when any work became available. Empire State College has offered me the chance to do things at my own pace. Marketing is a field that is universal. Even if I don’t obtain a position working in a marketing department or for an advertising agency, any career I may pursue will require me to market myself as an individual. This is the reason I decided on a marketing concentration as my major many years ago. In creating my degree plan, I have tried to keep the structure similar to the track I was previously on as well as fulfilling the other course requirements of Empire State College. The classes I am currently enrolled in, as well as the ones I plan to register for in the future all serve a purpose in me continuing my exposure to new marketing techniques and styles.

The Peculiarities of Social Learning Theory

Social Learning Theory The main aspects of the social learning theory also known as the social cognitive theory were developed by Albert Bandura and Walter Mischel in the 20th century. The theory is based on three main concepts and their correlation. These concepts are personality, environment, and behavior (Bandura, 1997). That is why the theory depends on the social perspectives and the ideas of behaviorists (Filingeri, 2011).Advertising We will write a custom research paper sample on The Peculiarities of Social Learning Theory specifically for you for only $16.05 $11/page Learn More According to the theory, while observing definite models of behaviors, a person can think them over and behave in relation to these models. Thus, a man learns these behaviors in the social context (environment) and imitates them in his behavior. Moreover, the environmental and cognitive factors are in a constant interaction and the other people’s models of behavior influence our reactions, attitudes, and actions (Bandura, 1997). This theory can be considered as credible with references to its main notions of reciprocal determinism and self-efficacy. Thus, many psychologists support the idea that an individual’s behavior is predominantly influenced by the environment and the interactions with other people and by personal traits which should be analyzed in their connection and interdependence. Mischel also adds such cognitive factors as expectancies, personal values and goals for forming the behavior (Filingeri, 2011). The social cognitive theory accounts for such aspects of personality as cognition (observation, analysis) and social behaviour according to definite models. Nevertheless, it does not include biological and hormonal factors which can influence the person’s attitude to the environment and his behavior without depending on the social context (Filingeri, 2011). That is why such major concepts of the social learning theor y as the idea that people can learn through observation and the impact of knowledge on the behavior can be argued. In their work, Cervone and Pervin accentuate that the aspects of the social cognitive theory developed by Bandura were too generalized with focusing on the average person and without paying attention to the variables in personalities. However, Mischel improved the description of the theory with working out the concepts of the variation patterns in the personal behaviour. Nevertheless, the social cognitive theory is still discussed as mainly basing on social aspects on which the cognitive factors depend without explaining the innate motivations for the actions (Cervone Pervin, 2010). Trait Theory In their researches, Gordon Allport and Hans Eysenck developed the opinion that a personality and the peculiarities of his or her behavior can be described with the help of discussing those traits which prevail in this personality (Filingeri, 2011). According to Allport’ s point of view, a trait can be considered as a stable characteristic of a personality (Allport, 2011).Advertising Looking for research paper on social sciences? Let's see if we can help you! Get your first paper with 15% OFF Learn More Moreover, it is necessary to pay attention to the fact that traits can be common (inherited, typical for all people) as well as unique (the features of their realization in the personal character). To analyze the peculiar features of traits and their influence on a personality, Allport determined three levels of the realization of traits in the personal character which are cardinal, central, and secondary traits (Allport, 2011). The main advantage of the theory is in the fact that it depends on the innate personal characteristics without focusing primarily on the social context, but considering it as the conditions for presenting the reactions. However, the discussion of five main aspects of personality or five main traits with their va riables as the main concepts of the trait theory (the Big Five) limited the theoretical considerations to the situation of analyzing the personality only according to these five traits without discussing the social context as the influential aspect. Thus, these major traits are extraversion, neuroticism, agreeableness, openness to experience, and dependability (Filingeri, 2011). In spite of the fact the trait theory accounts for personal physical, moral, and behavioral characteristics, they are considered as not equal in determining the personal behavior or reactions. The main accent is made on the moral aspect when the physical characteristic only accentuates the inherited nature of traits, and the behavioral factor is only necessary for understanding the realization the traits (Allport, 2011). Nevertheless, the investigations on the issues of the trait theory were conducted with basing on the examination of the peculiarities of the language and the usage of verbal characterization s for personalities and their traits, not the personal behavior (Filingeri, 2011). That is why this theory lacks the practical support for its main concepts. It is impossible to explain the impulsive and situational personal actions which cannot be considered as the part of the personality of this or that man with references to this theory. Thus, the theory does not account for immediate personal behaviors and reactions which are affected by the outside conditions (Filingeri, 2011). Evaluating the comprehensiveness of the trait theory, Cervone and Pervin concentrate on such aspects that the theory is rather inappropriate for explaining all the personality aspects because it focuses only on some of them. Moreover, it is impossible to consider a personality only according to his or her stable traits because the personality can change with the situation, and the theory does not discuss the causes for behavior which cannot be explained with focusing only on several traits of character ( Cervone Pervin, 2010).Advertising We will write a custom research paper sample on The Peculiarities of Social Learning Theory specifically for you for only $16.05 $11/page Learn More References Allport, G.

Dengue Fever Essays

Dengue Fever Essays Dengue Fever Essay Dengue Fever Essay In subtropical and tropical regions, the dengue virus represents a major threat to human health. The microorganisms natural hosts include mosquitoes, lower primates, and humans. Infection of the human host results in a biphasic fever with the potential to evolve into severe hemorrhagic disease. Over the past few decades, the virus genome structure, viral proteins, and viral antigens have been well characterized. Unfortunately though, the precise mechanisms by which the dengue virus causes disease remain unknown. Throughout history, major dengue fever epidemics have generally occurred at irregular intervals within the range of the mosquito vector. For instance, in 1922, one such epidemic may have affected between 1 and 2 million people in the southern United States. At present, dengue fever may cause more human morbidity and mortality than any other arthropod-borne viral disease (Henchal Putnak, 1990, pp. 376-396). The dengue viruses are currently endemic in most tropical areas of the world (Lanciotti, Lewis, Gubler, Trent, 1994, p. 65). It has been estimated that there could be as many as 100 million cases of dengue infection every year (Halstead, 1988, p. 476). The only natural hosts for dengue virus infections are mosquitoes, lower primates (e. g. , chimpanzees, rhesus monkeys, and macaques), and humans. Dengue Fever Dengue fever is a flu-like viral disease common throughout the tropical and sub-tropical regions around the world, mainly in urban and peri-urban areas. Today, it afflicts an estimated 50 million to 100 million in the tropics (Epstein, 2000). The virus has four antigenically related serotypes, which are named DEN-1, DEN-2, DEN-3, and DEN-4. Each dengue serotype is a variation of the flavivrus genus. Dengue is spread by the aedes aegypti, a domestic, day-biting mosquito that prefers to bite humans. Currently, there is no vaccine available to prevent dengue. Each type of the dengue virus is re-emerging worldwide, especially in the Western Hemisphere. Research has shown that several factors are contributing to the resurgence of dengue fever such as uncontrolled urbanization, increased international travel, substandard socio-economical conditions, and finally global warming. Global warming has shown to be a major contributor o the spread of dengue fever. On a molecular level, dengue fever is classified as a flavivirus and appears as a spherical particle, about 40 to 50 nanometers in diameter Dengue fever Dengue fever, also known as break bone fever, is an acute febrile infectious disease caused by the dengue virus. Typical symptoms include headache, a petechial rash, and muscle and joint pains; in a small proportion the dis ease progresses to life-threatening complications such as dengue hemorrhagic fever or dengue shock syndrome. Dengue is usually transmitted by the mosquito Aedes aegypti, and rarely Aedes albopictus. The virus has four different serotypes, and an infection with one usually gives lifelong immunity to it but only short-term immunity to the others. There is currently no available vaccine, but outbreaks can be prevented by reducing the habitat and number of mosquitoes, and limiting exposure to bites. Treatment of acute dengue is supportive, using either oral or intravenous rehydration for mild or moderate disease and blood transfusions for more severe cases. Rates of infection have increased dramatically over the last 50 years with approximate 50–100  million people being infected yearly. The disease has become global and is currently endemic in more than 110  countries with 2. 5  billion people living in areas where it is prevalent. Classification The World Health Organizations 2009 classification divides dengue fever into two groups: uncomplicated and severe. [1][2] This replaces the 1997 WHO classification, which was simplified as it was found to be too restrictive, but the older classification is still widely used. [2] The 1997 classification divided dengue into undifferentiated fever, dengue fever, and dengue hemorrhagic fever. 3] Dengue hemorrhagic fever was subdivided further into four grades (grade I–IV), with the two most severe being classified as dengue shock syndrome. [2] Signs and symptoms Infections from dengue virus range from asymptomatic, to a simple fever, to life threatening. [1] The incubation period (time between exposure and onset of symptoms) is 4–10 days. Most infections are very mild, and many probably experience no symptoms at all. [1][4] Most commonly symptoms include: sudden onset fever, headache (typically behind the eyes), muscle and joint pains, and a rash; the nickname break-bone fever comes from the associated muscle and joints pains. 1] If fever or other symptoms developed more than 14  days after returning from an endemic area, dengue is very unlikely. [3] The course of infection may be divided into three phases: febrile, critical, and recovery. [5] The febrile phase involves high fevers, frequently over 40  Ã‚ °C (104  Ã‚ °F) and associated with generalized pain and a headache; this usually lasts 2–7  days. [5] Flushed skin and some petechia (point-like hemorrhages in the skin) may occur at this point. [5] The critical phase follows the resolution of the high fevers and typically lasts one to two days. 5] During this phase there may be significant fluid accumulation into the thoracic cavity and abdominal cavity due to increased capillary permeability and leakage. This leads to depletion of fluid from the circulation and decreased blood supply to vital organs. [5] During this phase, organ dysfunction and severe bleeding (typically from the gastrointestinal tract) may occur. [3][5] Shock and hemorrhage occurs in less than 5% of all cases of dengue. [3] Those who have previously been infected with other serotypes of dengue (secondary infection) have an increased risk of developing severe complications. 3][6] The recovery phase occurs next if the person survives with resorption of the edematous fluids. [5] The improvement is often striking, but there may be striking itching and a slow heart rate. [3][5] It is during this stage that a fluid overload state may present with symptoms of cerebral edema such as an altered level of consciousness or seizures. [3] Prevention There are currently no approved vaccines for the dengue virus. [1] Prevention thus depends on control of and protection from the bites of the mosquito that transmits it. [7][17] The primary method of controlling Ae. aegypti is by eliminating its habitats. 7] This may be done by emptying containers of water or by adding insecticides or biological control agents to these areas. [7] Reducing open collections of water through environmental modification is the preferred method of control, given the concerns of negative health effect from insecticides and greater logistical difficulties with control agents. [7] People may prevent mosquito bites by wearing clothing that fully covers the skin and/or the application of insect repellent (DEET being the most effective). [8] There are ongoing programs working on a dengue vaccine to cover all four serotypes. 17] One of the concerns is, that a vaccine may increase the risk of severe disease through antibody-dependent enhancement. [18] The ideal vaccine is safe, effective after one or two injections, covers all serotypes, does not contribute to ADE, is easily transported and stored, and is both affordable and cost-effective. [18] A number of vaccines are currently undergoing testing. [13][18][19] It is hoped that the first products will be commercially available as early as 2015. Warning signs[2] Abdominal pain Ongoing vomiting Liver enlargement Mucosal bleeding High hematocrit with low platelets Lethargic Flood In Pakistan 2010 Flood In Pakistan The devastating flood in Pakistan had destroyed more than half of the economy of the country. The country which was already facing several other crises including terrorism,poverty,corruption,illiteracy    has now hit by another challenge in the form of flood. At this crucial time ,the world has pledge to help Pakistan in any form . U. N. Secretary-General Ban Ki-moon arrived in Pakistan on Sunday August 16 2010    to boost relief efforts as concerns grew about the 20 million people made homeless in one of the worst disasters to hit the country. Authorities said more flood surges were coursing down the River Indus and other waterways in southern Sindh province and were expected to peak later Sunday, causing fresh deluges. The river, which in better times irrigates the crops of millions of farmers, is 15 miles (25 kilometers) wide at some points- 25 times wider than during normal monsoon seasons. The United Nations said the rate of diarrheal disease continued to increase among survivors. Cholera, which can spread rapidly after floods and other disasters, had also been detected in the northwest, where the floods first hit more than two weeks ago. About 1,500 people have died in the disaster and more than 7. 9 million acres (3. 2 million hectares) of cotton, sugar cane and wheat crops destroyed.
