Transcript of Untitled Prezi
Humans have two lungs. The lungs are located on either side of the chest. The right lung is larger, and is divided into 3 parts. while the left lung is smaller, and divided into2 parts.
The Respiratory System
presented by: Sabrina, Brian, and Caleb
The main function of the organs in the respiratory system is to carry oxygen and release carbon dioxide.
The lungs are soft and have to be protected by ribs.
The purpose of our lungs are to carry in oxygen and carry out carbon dioxide.
How do lungs protect themselves
Lungs protect themselves in many ways such as...
The nose acts as an air filter to keep out large pollutants.
However, if large pollutants do get through the get stuck in mucus.
The lungs are able to do this because they are covered in a thin slick membrane called
Tuberculosis is a lung infection which is uncommon in some countries with well health care. This would be said to be a somewhat harmless infection.
Bronchitis is a disease in which the mucus membrane in the lungs become inflamed. People that have bronchitis may also have asthma. Bronchitis is also a harmless disease but, it would be a good idea to see a doctor if you might have it.
Asthma is when a muscle is wrapped around the Bronchioles contracts. Some people have to use a thing called an inhaler which is a breathing tool that alows people with asthma to breath easier.
The cough works when the bronchial tubes get irritated and tries to
release the cause
Most people think diseases as athletes foot or pink eye but, the diseases in the respiratory system are a lot worse. They could sometimes be harmless or it could be a life or death situation. Here are some diseases of the respiratory system.
Artificial lungs are man made lungs that do the job of real lungs. They are still working on making better artificial lungs. What they have now doesn't keep people alive long enough for a donor organ to be found.
Scientists are currently working on a device called a Bio lung which is no bigger than a soda can. The heart pumps blood into the Bio lung instead of a pump which could damages cells. The bio lung is hollow and has a fibrous plastic membrane, that has tiny holes, that are so small only gas molecules can get threw them.
new artificial lungs
Scientists are already trying to find cures for bronchitis and tuberculosis. Now it is Caleb's turn to talk about his research.
Now it is Brian's turn to talk about what he has found out about diseases.

A lung transplant is a surgical procedure to replace diseased lungs. It can be a dangerous operation, many things can go wrong. The body could reject the lung and the patient could die.
why people need lung transplants
If the lung becomes diseased it can shut down making it impossible to breath the best way to fix this problem is to replace the diseased lung with A healthy one, witch is called a lung transplant.
