The lungs are part of the respiratory system, which is how we breathe. The lungs are spongy, cone shaped organs. The right lung, which is slightly bigger, has three lobes or sections. The left lung has two lobes. The lungs take in oxygen when we breathe in and expel carbon dioxide when we breathe out.

Scientists have many different ideas about what goes wrong in the lungs of a person with cystic fibrosis, but it all begins with defective CF genes. Normally, the healthy CF gene makes a protein—known as CFTR (Cystic Fibrosis conductance Transmembrane Regulator)—that is found in the cells that line various organs, like the lungs and the pancreas.

The lungs are responsible for removing CO2 and therefore the level of CO2 in the blood. They do this by, if needed; increasing the respiration's of the lungs in an effort to remove the CO2.

During pregnancy, the blood volume increases dramatically, probably by about 40 to 50 percent. That's a large blood volume for a woman's heart, but amazingly, the body compensates very, very well.

Most likely because you don't dive in South Florida or the Caribbean. Here, in our backyard, the Third Lung is commonplace. You'll see them in use by recreational boaters an on live-aboard yachts. Some of the best lobster hunters in the Caribbean swear by their Third Lungs. On the west coast, recreational surface supplied air diving is relatively new.

Have you ever noticed people getting ready for any sporting event, to get the best performance from their bodies they always warm it up first to get the blood flowing.

Depending upon your responses to these questions, as well as the results of the physical exam, your physician may advise you to receive certain tests, to find out if your lungs have been damaged. Tests such as the pulmonary function test are used to see how well your lungs are working. Blood tests and a chest x-rays are also commonly used procedures.

A.) Someone who smokes marijuana regularly may have many of the same respiratory problems that tobacco smokers have. These individuals may have daily cough and phlegm, symptoms of chronic bronchitis, and more frequent chest colds. Continuing to smoke marijuana can lead to abnormal functioning of lung tissue injured or destroyed by marijuana smoke.

Yes, individuals may also develop asbestos diseases of the peritoneum (the lining of the abdomen) or the pericardium (the lining of the heart). Enter your contact information below and we'll send you our comprehensive mesothelioma information packet in 24 hours--FREE of charge.

Yes. Marijuana contains more tar than tobacco; is inhaled deeply and held in the lungs longer; is smoked to the end where the tar content is highest; and contains cancer-causing substances. However, since studies are difficult to do in marijuana smokers and since many of them also smoke regular cigarettes, it is hard to prove a definitive link to lung cancer.

Healed burns involving the lungs and throat may result in an altered voice which may be whispering or raspy. If the burn was very severe, a tracheostomy (breathing hole at the front of the throat) may be required, because the person can no longer breathe through the nose and mouth.

There have been minor radiological changes in the lungs reported in PXE. There can be changes in the lung tissues, but these changes would not be true scarring, such as when the body's tissues heal from an injury. [March 2006]

Shortness of breath, cough, chest pain and tightness are the most common complaints of sarcoidosis of the lungs. Severe scarring (fibrosis) of the lungs can cause respiratory failure. What is the effect of the disease on eyes? Burning, itching, red, light sensitive eves are the usual symptoms. If sarcoidosis of the eyes is not recognized and properly treated, blindness may occur.

Yes. Sarcoidosis commonly involves the lungs. In more than 90% of the patients chest x-ray film is abnormal. Any illness, particularly in individuals who were previously healthy, can cause anxiety and insomnia. Furthermore, anxiety may be related to lack of information about the disease. Prednisone can cause anxiety, insomnia, and irritability. We do not know the reason. Hypertension and diabetes are other diseases that are progressive in African-Americans patients.

Patients with mild lung disease (and that describes most sarcoidosis patients) have no problem. Only those patients who have extensive fibrosis of the lungs may need supplemental oxygen. In that case, your doctor will measure your oxygen content and advise accordingly. Prednisone suppresses granulomatous inflammation due to sarcoidosis. In some patients, sarcoidosis subsides while other patients might need prednisone for a long time.

Thrombophlebitis, sometimes called Deep Venous Thrombosis(DVT), can occur after any operation, but is more likely to occur following surgery on the hip, pelvis, or knee. DVT occurs when the blood in the large veins of the leg forms blood clots within the veins. This may cause the leg to swell and become warm to the touch and painful.

There have never been any recorded cases that state nail product fumes are harmful to the lungs. Remember, anytime a product has a strong odor, even cleaning products in your home, it's recommended these products only be used in well-ventilated areas. If the extensions were removed properly, the eggshell feeling will be temporary. Ask your technician to use a nail strengthener to help toughen them up.
