The Respiratory System

By: David Yonker The respiratory system is vital for the body to survive because it transports oxygen to the bloodstream. The cycle of the respiratory system starts when the diaphragm contracts and the rib muscles pull outwards making the oxygen to start its way down the trachea where it either goes to one lung or the other through the bronchi, then through branch-like tissue called bronchioles the oxygen passes to the alveoli where it is finally transported to the blood through veins and the cycle starts over again and again. The best-known organs in this system are the lungs which has a purpose of bringing in oxygen, “storing the alveoli”, and expelling carbon dioxide from the lungs. Although, the mastermind behind the respiratory system is the brain which tells the diaphragm and the rib muscles to start their purpose and if the brain had not done this then the body would not even work. The system in my opinion is the most vital organ because then the brain would not have oxygen which would make it not work and therefore the body can’t work. In In Ms. Bonnie`s class we learned a lot about the respiratory system and I hope that I can research it a lot more in the future. Links [] Pictures at: 1.  2.[] 3. [] Videos at: 1. 2. 3. By: Alvaro Jaramillo Asthma Asthma is very harmful disease that affects the air tube that carry’s air in and out of the individual`s lungs. The walls of the airways become very painful and start to rapidly increase in size it becomes harder to breath especially in the mornings and in the nights, the asthma`s effects are usually portrayed as allergies or irritated parts of the body. When the body reacts the lungs get narrower and its more difficult to breath. Some substances cause coughing when your asthma symptoms become worse than usual, it's called an asthma attack. In a severe asthma attack, the airways can close so much that the important organ, the lungs and therefore the whole body, can’t get oxygen. Asthma is treated with two kinds of medicines: quick-relief medicines to stop asthma symptoms and long-term control medicines to prevent symptoms. In my opinion this is a very serious yet fascinating disease. some of mythat i the internet. - http://www.medicinenet.com/asthma/article.htm - <http://www.youtube.com/embed/82gn [] [] [] [] [] [] ( this is a natural cure )

[] By: Jorge Rojas Lung Tuberculosis(LTB) TB is one of the most dangerous and bad ilnesses in the face of the earth. LTB is a contagious disease that consumes ones lungs, but one can prevent it by using antibiotics and taking care of ones self. The most famous symptoms are constant coughing of blood, pains in the chest, weight loss, not having hunger, chills, fevers, and sweating at night. This disease was called the consumer in the early 1900's,and 10% out of the 100% of people who got it were affected this number is the same today, out of that 10% half of them die. The most common type of TB is the lung TB and as I've said it consumes your body parts, in this case the lungs and if you get it you can die. I find this disease very interesting but dangerous, serious, and bad.http://en.wikipedia.org/wiki/TuberculosisBlue-Trachea Red-Right Lung Orange-Left Lung Videos @: 1.http://www.youtube.com/watch?v=HiT621PrrO0 2.http://www.youtube.com/watch?v=TU4WBbwOWU4 3.[]

Lung cancer
==== The principal function of the lungs is to exchange gases between the air we breathe and the blood. One of the most dangerous diseases in the lungs in Cancer. Lung cancer is the number-one cause of cancer deaths in both men and women in the U.S. and worldwide.Lung cancers can arise in any part of the lung and is caused by Smoking, been a passive smoker, Asbesto ( silicate fibers that can persist for a lifetime in lung tissue), Radon gas (a natural, chemically inert gas that is a natural decay product of uranium), Familiar predispositions, lung desease and family history of lung cancer. There are two types of lung cancer and it depends if the malignant cells are small or non-small. Treatment of lung cancer can involve a combination of surgery, chemotherapy, and radiation therapy as well as newer experimental methods. Some of the things that can be done to prevent lung cancer are: Smoking cessation which is the most important measure that can prevent the development of lung cancer. Some methods that allow early detection of cancers, such as the helical low-dose CT scan, also may be of value in the identification of small cancers that can be cured by surgical resection and prevented from becoming widespread, incurable, metastatic cancer. ====

By:Jorge Rojas Coronary Artery Disease[(CAD)Cardiovascular system) CAD is a dangerous illness that will narrow your veins and make it hard for blood to pass through them. This is a result of a plaque buildup in your arteries. CAD develops at an early age because of cholesterol, as one grows up the plaque in ones artery builds up and starts to get stronger. It will inflame the blood vessels and will increase the chances of one gatting a heart attack. In most cases the blood vessel will develop new ones around the plaque to keep on with the supplyment of oxygen to the blood, but in cases of people who are stressed out or have exertions this may not be possible. If the supplyment of blood isnt possible to the heart one may have a heart attack. Inchsemia which is the occuring of a heart attack may happen while exersising, eating, exitment, stress, and exposure to cold.http://www.webmd.com/heart-disease/guide/heart-disease-coronary-artery-disease [[image:humanbodyandpizza/cad_2.jpg]][[image:humanbodyandpizza/cardiovascular_system.png width="618" height="280"]] [[image:humanbodyandpizza/cad.jpg]] Videos @: 1.http://www.youtube.com/watch?v=DAXa4eR1s0M 2.http://www.youtube.com/watch?v=VUtehbgbpRk&feature=related 3.http://www.youtube.com/watch?v=Ta_HNfU5aDM 4.http://www.youtube.com/watch?feature=endscreen&NR=1&v=An3E_Yuejts
