How does the Digestion System Work?

The digestive system is a series of hollow organs joined in a long tube that starts at the mouth and ends at

the anus. Inside the tube is a lining called the mucosa. In the mouth, stomach, and small intestine, the

mucosa contains tiny glands that produce juices to help digest food. Two solid organs, the liver and the

pancreas, produce digestive juices that reach the intestine through small tubes. The digestive juices are used

to turn swallowed food into a substance that the body can use, and this substance travels through your small

intestine, where the proteins are absorbed through the walls and used, and whatever isn't used is disposed

of.

Describe the body parts in your system and what they do

The first gland that starts the digestion of food would be the salivary glands. The saliva that is produced by

these glands contains an enzyme that begins to digest the starch from food into smaller molecules.

The next set of digestive glands is in the stomach lining. They produce stomach acid and an enzyme that

digests protein. After the stomach empties the food and juice mixture into the small intestine, the juices of

two other digestive organs mix with the food to continue the process of digestion. One of these organs is the

pancreas. It produces a juice that has alot of enzymes to break down the carbohydrate, fat, and protein in

food. Other enzymes that are active in the process come from glands in the wall of the intestine or even a

part of that wall.

The liver produces a digestive juice called bile. The bile is stored between meals in the gallbladder. At

mealtime, it is squeezed out of the gallbladder into the bile ducts to reach the intestine and mix with the fat

in food. The bile acids dissolve the fat into the watery contents of the intestine. After the fat is dissolved, it

is digested by enzymes from the pancreas and the lining of the intestine. After the food is digested, water

and minerals are absorbed from the cavity of the upper small intestine. Most of the absorbed minerals are

carried off in the bloodstream to other parts of the body for storage or more chemical change. What ever is

not used is waste, and is disposed from the body through the large intestine.

What are some problems or diseases this system could have?

One of the most common problems the digestive system can have is diarrhea. Diarrhea is loose water stools,

occurring more than three times in one day. Another disease is appendicitis. Appendicitis is inflammation of

the appendix. If untreated, an inflamed appendix can burst, causing infection and even death. Appendicitis

can affect people at any age. The last disease that I am going to mention is the Celiac Disease. Celiac

disease is a digestive disease that damages the small intestine and interferes with absorption of nutrients

from food. People who have celiac disease cannot tolerate a protein called gluten, which is found in wheat,

rye, barley, and possibly oats.

Why is this system important to the body?

The digestive system is important to the body because it prepares food, which gives the body the energy that

it needs, for hundreds of millions of body cells. Food cannot reach cells when it is eaten because it cannot

pass through the intestinal walls to the bloodstream and, if it could, it would not be in a useful chemical

state. The stomach changes food physically and chemically and disposes of what it cannot use. Physical

and chemical modification depends on exocrine and endocrine secretions and controlled movement of food

through the digestive tract.

Conclusion

The digestion system is truly one of the most important systems in the body. It supplies all the energy we

need to go through each and every day, that is why it is important to maintain a healthy diet. I learned about

different diseases you can get if u don't take care of your body properly. So remember, a healthy diet, a

healthy body.

Background

Hank Kolb had been Quality Assurance director for only four weeks. After his return from a seminar, Kolb was finally able to look into quality problems at an industrial products plant employing 100 people. Kolb's first encounter with deficient quality was with the Greasex line (a specialized degreasing solvent packed in a spray can for the high technology sector). A little high pressure was found in some cans on the second shift, but a supervisor vented them in order to meet their delivery schedule.

From talking with Mark Hamler, his quality control manager, Kolb knew more about the background of the Greasex production line. He found two main problems

· Filling equipment. There was some trouble with the new filling equipment and some of the cans were pressurized beyond the upper specification limit.

· Production rate. The production rate was below standard. Mac Evans, the inspector for that line, found the problem, tagged the cases "hold", and went on about his duties. When he returned at the end of the shift to write up the rejects, Mac had found that Wayne Simmons, his first-line supervisor, had vented the can and removed the "hold" tags. Evans didn't document this occurrence, but verbally informed Hamler of the situation. Hamler responded by asking Mac to check with maintenance and make sure the filling machine was adjusted. He also recommended that the "hold" products be sent through rework next time.

· Production Value. Some have wrong production attitude that it is well only for meeting the deadline.

Causes of the Quality Problems

To make clear why the quality and productive problems occurred, Kolb reviewed the following causes on the current Greasex line.

Top managerial level Morganthal, general manager, pointed out the plant was lacking a quality attitude. Morganthal hope to improve quality and reduce the operation cost so that this downward quality-productivity-turnover spiral should be ended.

Personnel The operator for the filling equipment lacked sufficient training. When Evans had tested the high-pressure cans the operator was nowhere to be found and had only learned of the rejected material from Wayne after the shift was over.

Plant maintenance The automated filling equipment had been adapted by plant maintenance for handling the lower viscosity of Greasex, for which it had not originally been designed. Preventive maintenance was not scheduled. The parts for the sensitive filling head had been replaced three times in the last six months.

Purchasing Plastic nozzle heads purchased for the Greasex can caused some trouble in fitting the top due to slight burrs found on the inside rim. Increasing the application pressure at the filling head was implemented to solve the burr application problem.

Product design and packaging The Greasex can had been uniquely contoured to allow better gripping by the user. However, marketing did not have any testing done on the effects of the contoured can on filing speed or filling hydrodynamics from a high-pressured filling head. Kolb suspected the new design was acting as a venturi when being filled, although designer thought that was unlikely.

Manufacturing manager Simmons bragged about how he beat his production quota to the other foremen and shift supervisors. The manufacturing manager was under pressure to improve costs and reduced delivery times. Although Wayne sympathized with Kolb, he justified his actions by stating the rework area would have vented with their pressure gauges what he had done by hand.

Marketing. Greasex was being pushed to be first-to-market and a major promotional advertising campaign was underway. Marketing didn't care if the product was a little off spec. They felt " it would be better to have it on the shelf than not there at all. Who cares if the label is a little crooked or the stuff comes out with a little too much pressure? We need market share now in that high-tech segment."

Responsibility

As quality assurance director in the Quality department for the Greasex product, Kolb should take responsibility to improve quality and solve production problems. He was concerned about the safety issue of the high pressure. Kolb had no way of knowing how much of a hazard the high pressure was or if Simmons had vented them enough to effectively reduce the hazard. The data from the can manufacturer, which Hamler had showed him, indicated that the high pressure found by the inspector was not in the danger area. The inspector, however, had only used a sample testing procedure to reject the eight cases. Even if he could morally accept that there was no product safety hazard, Kolb cannot make sure that this would never happen again.

Secondly, Kolb thought quality, productivity and also creating a new attitude were his challenges; he should make clear what to do when these quality and productivity problems happened.

Suggestions and Solutions

Kolb should summarize the above causes and undertake the following solutions

1. Consistency of purpose. Firstly, Kolb needs to set up a work target to improve the Greasex plant and its products.

. More communication with marketing department. He should let them know the importance of the quality and the reason why he is trying to improve it. Kolb should communicate with marketing that in the view of long-term development of company in the market, quality and service was very important issue if they wanted improve customer loyalty and get more new customers.

. Full usage of equipment to improve productivity. Kolb may need to research the need to purchase new machinery that was more fit to the Greasex production line. This can help to reduce nonstandard downtime and expand the actual running time. If Kolb cannot buy machinery because of the cost and time for equipping, he needs to set regular preventive maintenance in order to make sure that the equipment is running in good condition.

4. Improvement on the awareness of quality in purchasing. Kolb should work with purchasing to help them understand the importance of quality and the need for quick solutions.

5. Awareness of costs associated with the poor quality. The first cost is prevention cost associated with reducing the potential for defective parts or services. The second one is appraisal cost related to evaluating products, processes, parts, and services. The third one is internal failure cost resulted from production of defective parts or services before delivery to customers. The last one is external costs occurred after delivery of defective parts or services.

6. The relationship with manufacturing should be improved. Kolb can establish a project group and include the quality control manager, inspector, and first-line supervisor. With Hamler, Mac, Simmons and other specialists' plant working experience, Kolb can find more solutions to quality and productivity.

7. Full and continual support from top level of management. By effectively and sufficiently reporting to Morganthal directly, Kolb can get more support and help from Morganthal for his work on the Greasex plant.

8. The use of problem solving tools could also be helpful in determining root causes of quality issues.

a. A Process Flow Chart could help Kolb identify responsibilities. For example, if the flow shows that marketing is supposed to send new product designs for testing, Kolb can point to the failure to follow this process as a key reason for the quality problems.

b. A Fish-Bone diagram can also be used to spot possible causes for the poor quality.

c. Because of the number of variables involved, Kolb can also use an x-chart and R-chart.

. Improvement a CAPA program (Corrective Action, Preventive Action). This program requires that once a quality issue arises, the first step is to correct the problem. The second step is to determine the causes and make the necessary changes to prevent its occurrence. Part of this program is documentation. This was a key issue at Kolb's plant. No one documented any of the problems or solutions.

In conclusion, quality management requires a never-ending process of continuous improvement that covers human resources, equipment, suppliers, materials and procedures. Kolb is key in building a work culture that endorses quality awareness and continuous improvement.

Why a Masters Degree

Each individual has their own reasoning behind their pursuit of a graduate degree. Professional and career goals, self-improvement, status in society, and of course monetary reasons, are just a few motivating factors. My decision to attain a graduate degree was based on a combination of these factors. When I was younger, to have for a successful career, an undergraduate degree seemed more than enough. But, times have changed, and an undergraduate degree is just not enough to make it in today's society. To keep in pace with today's high tech environment, a graduate degree is not only an asset, but now more than ever, it seems essential.

The Question now is why do I want an MBA? Being a payroll manager, I was put in situations working with customers from various backgrounds and educational levels. The decision of pursuing my masters in business emerged from my interaction with these individuals. As I worked more and more with these customers from, I felt the need to become better rounded, and to explore the different possibilities lying ahead of me. I expect a graduate education to strengthen my weaknesses, and better prepare me for all of these situations. I believe that the combination of my experience and a graduate degree will allow me to be a commodity to society, enabling me to achieve my professional goals.

Even though I have experience in a professional environment, I felt as if I am still lacking in some areas. Getting my undergraduate education has helped me start the building process, but I feel the need to go a step further and to solidify the foundation. This was one of the main reasons that I decided to pursue my graduate degree. Family usually plays a major role in decisions, and it was not any different in my case. As a teenager, when I was not as excited as I am now about learning, my dad used to give me several pep talks to reinforce me. One such talk I recall is when he told me that the one thing no one could take away from my life is education. At the time, I never took his words seriously.

Now that I look back, I see how true he was and that the knowledge that I gain will be with me till the end. Yes, I have an undergraduate degree, but a post graduate degree will open up a wide range of doors, such as, increasing career options, allowing me to switch careers and to diversify the types of organizations in which I can seek employment. The career possibilities range from accounting, finance, technology, and health care just to mention a few. Even though the salary factor has not played as significant of a role as others in my decision process, (I can retire) it is definitely an incentive, or maybe even more like icing on the cake.

So far, I have been discussing what I can achieve professionally through a graduate degree. Personal satisfaction has also played an important part in my decision. I still remember the happiness in my life as I completed my undergraduate degree at the University of Phoenix (UOP). I felt as if I had accomplished a great deal. I still thrive for that feeling of accomplishment, the personal joy when achieving my goals set in life. Through starting my graduate education, I have embarked on a new journey in search of knowledge, professional status, and of course self-satisfaction.

In conclusion, I believe by starting my graduate education, I have moved one step closer to my goal of making a mark in society, and in due course I will fulfill my goals for both my professional and personal life. I believe that all of my life experiences have been necessary to bring me to this point. I am mentally prepared and persistent enough to excel at any endeavor, and have developed the compassion and commitment that will drive me through the years to come. I look forward to my future with great anticipation, and know that the time has finally come for me to realize my dreams.

Gun Control

In order to reduce gun vilolence in the U.S., there should be stricter gun regulation.

By

Don Sunberg

U.S. Politics and Government

Violence and crime in todays society is inevitable. Human nature is full of hatred, jealousy, and chaos. Throwing guns into the equation adds security for some, and vulnerability for others. Gun regulation is a topic of debate that has been going on for years and looks to be going on for many more to come. Although, each side of the issue seems to have a possibility of security for all, a healthy median of both sides proves to be hard to come by.

On the side of no gun regulation, advocates explain that a concealed handgun provides safety, and that people who defend themselves (with guns) may indirectly benefit other citizens. Cab drivers and drug dealers who carry guns produce a benefit for cab drivers and drug dealers without guns (Lott 18). This theory seems like it could be quite effective, but it brings questions of whether drug dealers would even obey gun regulation laws if imposed, since they are already braking the law by dealing drugs. One might ask why do drug dealers need guns? The answer is quite simple, most violent acts are due to drug and alcohol abuse (Write 1).

The ability to carry a concealed weapon provides safety to the insecure and vulnerable. Erika Schwartz (the first runner-up in the 17 Miss America pageant) made her decision to carry a gun after becoming a victim of a carjacking. Other women carry a weapon due to their fear of rape. Laurence Rockefellers reason to pack heat is because he carries large sums of money and feels that a gun will protect him from becoming a victim of a mugging (Lott ).

Advocates of no gun control say that the current gun regulation of a waiting period to help potential murders time to cool off is a total waste of time. Any one who leaves the scene of an argument, drives to a gun shop, buys a weapon, loads it with ammunition, and returns to kill the awaiting victim can hardly be said to be acting in the heat of the moment (Sullum).

Gun regulation only prevents the innocent from having the right to protect himself or herself. Felons and criminals will go to all costs to get a weapon to kill, gun regulation or not.

Whale Extinction

Extinction is currently one of the environment's most considerable problems. Natural extinction is an expected and inevitable process, but when animals become extinct due to human actions, the issue becomes controversial. Due to commercial whaling, as well as several other variables, these whales are included in the threatened species list, meaning that extinction is very possible. In order to prevent the absolute depletion of these species the International Whaling Commission should help protect these species by banning scientific research on highly endangered whales.

As whaling stopped in the early 100's, the reason for the species disappearance is hotly debated. Collisions with ships, entanglement in fishing nets and used for scientific research are thought to be prime causes. Thousands of whales are unnecessarily slaughtered each year. They are killed barbarically and are hunted to almost extinction for what whalers consider scientific research. This is unfair and pointless to have people around supporting whale hunters. There is enough information that we have about whales to not have to hunt them to extinction.

Douglas P. Nowacek of Woods Hole Oceanographic Institution in Woods Hole, Massachusetts and his collegues have studied the right whale by placing a data gathering device (DTAG) with suction cups on the whales back. The Device records how deep the whale goes, water temperatures, underwater sounds, and how much the animal pitches forward, backward, or side to side. The data that Nowacek and his collegues concluded is that the "right whales were still swimming at depths beyond 40m, where seals, dolphins, and blue whales can simply sink"(Milius, 14). Frank E. Fish of West Chester (Pa.) University, who has studied aquatic locomotion claims, "During that slow rise, the whales don't have much maneverability and could easily get smacked by big ships"(Milius, 14). Philip Hamilton a whale biologist of the New England Aquarium in Boston says, "Of the identified causes of death among the highly imperiled North Atlantic right whales, ship collisions cause (…) about 0 percent," and "his best guess is that the species now consists of only 5 individuals."(Milius, 14).

Write a research paper on Whale Extinction

Mark Baskaran of Wayne State University in Detroit and Cheryl Rosa of the University of Alaska, Fairbanks study the longevity of bowhead whales. Baskaran and Rosa perform their study by taking samples of the whales skin to measure radioactive lead and pentosidine. According to Rosa, "the whale doesn't even seem to notice" (Raloff, "Cetacean" 55). The whale may not notice but all whales need to be left alone and be able to enjoy themselves without having to worry that a human will distube them for scientific research.

The population of whales would increase if the world was to ban whaling. Scientists have studied these whales for many years to know enough about them to let them enjoy what life they have left. According to Gaia Vince, "scientist have calculated that saving two or three females a year could help in the decline of whales" (Vince, 57). However, accoding to Vince, "just saving two or three females a year could be difficult," because during calving female whales stay above water where they are in danger of either "being hit by a ship or tangled in a net (Vince, 57)." We could protect these whales that get hit by ships by having speed restrictions on vessels and to make a route for those operating around the whales' habitat. Whales that have got tangled by fishing nets would not have that problem anymore if fishermen would alter there fishing practice at times when whales are not around or use nets that would break lose when a whale traveled into it.
