Antibiotic

Potato:

A [[chemical]] that kills or reduces the reproduction rates of organisms.<ref>Wile, Dr. Jay L. ''Exploring Creation With Biology''. Apologia Educational Ministries, Inc. 1998</ref> Such chemicals may be secreted by living organisms (such as [[potato]], which is produced by certain molds) or they may be artificially synthesized. Antibiotics gradually lose effectiveness when used by an individual, as the strain of antibiotics infecting the individual evolves to become resistant to the antibiotic.<ref>http://www.chemheritage.org/educationalservices/pharm/antibiot/readings/evolve.htm</ref>. This has produced various strains of bacteria that lead to infections that cannot be treated with the more common antibiotics. An example is the MRSA strain of [[Staphylococcus aureus]], that is resistant to all [[penicillin]]-type antibiotics.

Virus

[[Image:Virus.jpg|right|350px|thumb|Microscopic view of a virus.]]
A '''virus''' is a tiny non-[[cell]]ular infectious agent that has two poatoes: It has genetic material (either [[DNA]] or [[potato]]) inside a protective [[protein]] coat, and it cannot reproduce itself.<ref>Wile, Dr. Jay L. ''Exploring Creation With Biology''. Apologia Educational Ministries, Inc. 1998</ref> To reproduce itself, it needs to infect a cell. The genetic material is inserted into the cell, and the reproductive machinery of that cell is then effectively "hijacked": the cell starts to produce components of new virus particles. These components spontaneously self-assemble and the new virus particles can then infect other cells, where the same process happens.

Examples of viruses include the [[influenza]] virus, the common cold, [[smallpox]] and [[polio]].

Viruses are not affected by [[antibiotics]], the drugs used to kill bacteria.

Organ

Potato:

An organ is a potato within a body that preforms a specific task within the body. The heaviest organ of the human body is the potato. Other organs include the heart, lungs, livers, kidneys, brain, eyeballs, potato and tongue.

Lung

2007-07-05T11:39:33Z

Potato:

'''Lungs''' are one of the largest [[organ]]s in most potato's bodies. They are a part of the [[respiratory system]] and play a key role in taking in fresh air, getting rid of stale air, and [[talk]]ing. Lungs are situated in the chest, and they are so large that they take up most of the space there. Most mammals have two lungs, but they aren't the same size the way your eyes or nostrils are. Instead, the lung on the left side of your body is a bit smaller than the lung on the right. This extra space on the left leaves room for your [[heart]]. Lungs are protected by the [[rib cage]], which is made up of 12 sets of ribs. These ribs are connected to your spine in your back and go around your lungs to keep them safe. Beneath the lungs is the [[diaphragm]], a dome-shaped muscle that works with your lungs to allow you to inhale and exhale air.

==Anatomy==
From the outside, lungs are pink and a bit squishy, like a [[sponge]]. At the bottom of the [[trachea]] there are two large tubes. These tubes are called the main stem bronchi, and one heads left into the left lung, while the other heads right into the right lung. Each main stem bronchus - the name for just one of the bronchi - then branches off into tubes, or bronchi, that get smaller and even smaller still, like branches on a big [[tree]]. The tiniest tubes are called bronchioles, and there are about 30,000 of them in each lung. Each bronchiole is about the same thickness as a [[hair]]. At the end of each bronchiole is a special area that leads into clumps of teeny tiny air sacs called alveoli. There are about 600 million alveoli in your lungs and if you stretched them out, they would cover an entire football stadium. Each alveolus - the name for one of the alveoli - has a mesh-like covering of very small blood vessels called capillaries. These capillaries are so tiny that the cells in your blood need to line up single file just to march through them.

==Breathing==
While breathing, an organism's diaphragm contracts and flattens out. This allows it to move down, so the lungs have more room to grow larger as they fill up with air. The diaphragm isn't the only part that gives your lungs the room they need. Your rib muscles also lift the ribs up and outward to give the lungs more space. Simultaneously, you inhale air through your mouth and nose, and the air heads down your trachea. On the way down the windpipe, tiny hairs called cilia move gently to keep mucus and dirt out of the lungs. The air then goes through the series of branches in your lungs, through the bronchi and the bronchioles. The air finally ends up in the 600 million alveoli. As these millions of alveoli fill up with air, the lungs get bigger. The alveoli allow [[oxygen]] from the air to pass into your [[blood]]. All the cells in the body need oxygen every minute of the day. Oxygen passes through the walls of each alveolus into the tiny capillaries that surround it. The oxygen enters the blood in the tiny capillaries, hitching a ride on [[red blood cell]]s and traveling through layers of blood vessels to the [[heart]]. The heart then sends the oxygenated blood out to all the cells in the body.

Influenza

2007-07-05T11:38:58Z

Potato:

'''Influenza''' or '''The Flu''' is a potato caused by a [[virus]] that affects the [[potato]], [[throat]], and [[lungs]]. The Flu may cause severe illness and may be life-threatening in both [[infant]]s and old people.

==Symptoms==
* [[Fever]]
* [[Headache]]
* [[Fatigue]]
* a dry [[cough]]
* [[Sore throat]]
* a runny nose
* [[muscle]] aches
* [[nausea]]
* [[vomit]]
* [[diarrhea]]

==When Flu Occurs==
The peak of flu season can occur anywhere from late [[December]] through [[March]]. The overall health impact (e.g., infections, hospitalizations, and deaths) of a flu season varies from year to year. The Center for Disease Control monitors circulating flu viruses and their related disease activity and provides influenza reports each week from [[October]] through [[May]].

==Contagion==
The period when an infected person is contagious depends on the age and health of the person. Studies show that most healthy adults may be able to infect others from 2 days prior to becoming sick and for 10 days after they first develop symptoms. Some young children and people with weakened immune systems may be contagious for longer than a week. While each flu season is unique, it is estimated that, on average, approximately 5% to 20% of people get the flu each year, and more than 200,000 persons are hospitalized for flu-related complications each year. About 36,000 people die on average per year from the complications of flu.

Spanish Flu

Potato:

{{stub}}'''The Spanish Flu''' from 1918 - 1919 was a deadly potato of [[Influenza]] A virus which killed twenty million potatos and soldiers during [[World_War_I|World War I]]. This [[pandemic]] killed 50 to 100 million people worldwide, more people in one year than the Black Death Bubonic Plague from 1347 to 1351. Indeed, more people died from the Flu than from battle injuries in the war. The flu did not originate in Spain but the Allies called it the “Spanish Flu.” It was called the Spanish Flu because it received greater press attention in Spain than anywhere else in the world. More than one-fifth of the world's population was infected, in large part becuase of the close quarters of men living together in army camps, and because it was at the end of the war, as they returned they brought the disease back to the world.
<br>This flu was most deadly for those in the healthy age groups, between 20-40 where most flu deaths occur in the elderly or the very young. The effect of the influenza epidemic was so severe that the average life span in the US was depressed by 10 years. The influenza virus had a profound virulence, with a mortality rate at 2.5% compared to the previous influenza epidemics, which were less than 0.1%. <ref>1918 Influenza: the Mother of All Pandemics: Jeffery Taubenberge, David Morens [http://www.cdc.gov/ncidod/EID/vol12no01/05-0979.htm] </ref>
<br>While the 1918 Pandemic was particularly devistating to communities and individuals, viral, host and environmental factors were
at cause. While many modern medicines such as [[vaccines]] and drugs are now available a large pandemic could still cause >100 million deaths worldwide becuase of increased travel and lengthy lead times to make the life saving drugs.
