Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
Can someone live years without ever knowing they have stage IV lung cancer or kidney cancer?. And only to find out later on during an autopsy that it was present?
Full autopsy: Only a complete autopsy will answer the key questions. Was this really a gunshot wound? Can we recover the bullet? Did the person suffer greatly? Was the person already dead from something else (as a clever lawyer would argue)? Did the person have a brain problem that made them act strangely and then get shot? Are there other bullets? ...Read more
Perhaps: It can take a very long time for smokers lungs to recover from injury. In fact your risk of both cardiac disease and lung cancer do not go back down to normal for 10-15 years after you stop. Smokers loose a lot more lung function per year while non-smokers only loose a small amount of lung function per year. ...Read more
We consider it: Cancer until proven otherwise, but even with history of living in endemic areas of histoplasmosis, coccidioidomycosis, it is risky to watch without repeat tests. Thoracoscopic procedures can excise with fewer adverse effects that standard thoracotomy. Laying odds is not a game to be played when your life is in the balance. ...Read more

Shortness of breathing esp. during work, but normal heartbeat. Clear lungs. Goes away if I lie down. Non smoker. Should I be worried?

Read nonmenthol smokers more likely to get lungcancer than menthol smokers. This cause they smoke more Or is menthol easier on the lungs? Or untrue
Not true: Several very large case control studies involving thousands of patients have been reported showing NO difference in cancer rates, heart disease, emphysema and bronchitis between smokers of mentholated and non-mentholated cigarettes. In fact, African-American men smoking menthol cigarettes have a higher rate of lung cancer than those smoking non-menthol, but appears to be due to more cigarettes. ...Read more
What are the possible causes of scarring in the lungs. My dad now 80 used to be a smoker but quit it some years back has this scarring in lungs. Help.
Probably just that: As doctors, we don't usually call anything scars of the lungs so I can't be sure what you mean. Smoking may disrupt lung structure leading to what is called emphysema. Pulmonary fibrosis may occur spontaneously. Old pneumonia may leave permanent changes, which seems like a scar. There is no cure for these diseases but treatment may help. Your dad should get a lung specialist if at all possible. ...Read more

It's decreased.: It is reduced compared to that of a non-smoker due to lung disease. According to the CDC, smoking can stunt lung development in teens and can increase the risk of asthma, TB, emphysema and cancers. Smoking damages the elastic lining of air sacs and causes scarring which can restrict air flow in or out. ...Read more
Blow cigarette smoke: Through a tissue and you will have some idea. That yellow color ultimately becomes darker, brown and then black, and your lungs are filled with it. Healthy lungs are pink, and even non-smokers get a few dark spots here and there from air pollution, but smokers have very dark and even blackened lungs. More importantly, the airways and air sacs are damaged and don't work to give us enough oxygen. ...Read more
It depends: The risk of cancer depends on the characteristics of the lesion on the lung, but overall the majority of nodules in the lungs of nonsmokers (and even smokers) will turn out to be benign. Even in high risk current and former smokers being screened for lung cancer, 96% of nodules were benign. ...Read more
Easier to breathe...: "Room air" is approximately 21% oxygen. People need oxygen to make their vital organs (brain and others) function well. If a person's lungs are damaged, that person may not absorb oxygen well. By administering oxygen to the patient, the percentage of oxygen in the "air" is increased allowing for the person to oxygenate their blood more readily and thereby deliver oxygen to vital organs. ...Read more
I was a light smoker for 4 years and I quit a month ago. The reason I quit was due to sharp pains in the lungs. Since then i rarely obtain it.what is it?
Impossible to say: With certainty what YOUR pain is, but most people your age who have chest pains and are smokers have inflammation of the airways (acute/chronic bronchitis) and this can be associated with pain, especially with coughing. However, nobody can make a diagnosis without a full history, examining you and (perhaps) other tests such as an EKG and Chest Xray. See your doctor. Congrats for quitting smoking! ...Read more
Most often smokers..: Dip stands for desquamative interstitial pneumonia. It was first described in 1956. Occurs most commonly in middle-aged adults who are cigarette smokers. It is a type of lung disease in which alveoli (tiny air exchange sacs in the lung) become filled with cells and patients experience shortness of breath. It is treated by smoking cessation and corticosteroids. Complete recovery is possible. ...Read more
Condition exists.: During my training years, I performed an autopsy (cadaveric dissection) of a patient who died from "metastatic encephalopathy". I scraped out what literally looked like charcoal from the lymphatic tissue in her lungs. We knew she was a heavy smoker. I don't know if she was a (female) miner, but I doubt it. But if that didn't meet the definition of "black lung", I don't know what would. It IS real! ...Read more

What happens if a smoker's lung, the simple squamous et is replaced w/ stratified et, why is it bad?
While I don't: Understand the molecular biology of it, chronic irritation of respiratory (and other kinds of) epithelium results in metaplastic changes — making stratified squamous epithelium — prior to developing neoplastic changes in individual cells — the production of malignant cells. If this is you, it is time to quit. Help is available. ...Read more

I was a heavy smoker for 14 years (1 pack a day) and i now I quit since 1month is an intensive cardio workout can help my lungs to recover fast?
Not really: You can't speed up recovery of your lungs but you can slow the damage and prevent future problems — from smoking or not. Cardio workout is one good method for that — it exercises your heart and lungs and causes frequent gas exchange from as much of your lungs as possible. ...Read more
