in detail can you please describe what happens in the lungs in : asthma, emphysema, and lung cancer?

These are three different conditions and could take pages to describe. \n \nAsthma:  Is a reaction of the the small tubes in the lungs to a virus, an allergen, cold air, or various other factors.  The tubes react in three ways.  One they narrow and therefore produce a wheezing sound when breathing out, two they produce mucus thus clogging the tubes even more then three they swell.  The best way to prevent asthma is keep the tubes in good shape. (e.g.. use a preventative)Asthma is treatable but if acute can make it difficult to talk so it is a good idea to not leave it too long before seeking help.  (A good friend died on his neighbours front step unable to call out)\n\nEmphysema:  Is a deterioration of the the air sacs at the end of the tubes described above.  Commonly caused by smoking for years (both by direct smoking or second hand smoking).  The air sacs loose there elasticity and do not work as well as they used to therefore limiting the persons ability to exchange oxygen by limiting the amount of air breathed in.  Emphysema is not reversable.\n\nLung cancer:  A growth of cancerous cells within the lungs that destroys good lung tissue and eventually will take over if not treated.\n\nAll these conditions have the ability to severely limited your life and have the capacity to kill you.  The tubes of a person who has died of an asthma attack when dissected are like solid branches of a tree made of mucus, therefore not letting any air in or out.

Since he had some fluid in the healthy lung, it may mean that this only lung is affected by cancer too.\nthere may be 1or 2 other possibility but to be honest cancer is # 1 reason.\nhole in his lung ? may mean pneumothorax which usually resolves by itself but needs some time (may be weeks, my brother had a hole in his lung after heart surgery & it healed after 1 month).\ni wish your uncle good health

a) When you inhale, air goes through your nostrils and into you air ways all the way to your lungs.\nb) Inside your lungs are small alveoli that capture O2 molecules and trap them for your red cells to start working.\nc) Each red cell is like a carrier that excahnges O2 molecules for CO2 moluecules (those of used air on your bloodstream)\nd) Red cells go through your blood to every tiny place in your body giving oxygen where is needed and taking CO2 back to the lungs.  Your lungs get rid off those CO2 molecules when you exhale.\ne) You heart pumps blood in two directions:  It makes the blood with carbon dioxide (CO2) go to the lungs and the blood that is oxygen rich, go to all your body.  Your brain is the primary oxygen client in your body.

If you are a smoker and continue to smoke.  expect to die a terrible painful death with slow suffocation.\nIf you have quit smoking, your lungs will have some time to heal and you will not get worse unless you get pneumonia or some other type lung infection.

The problem is if you inhale it. That can damage your lungs

Asthma is a disease of the human respiratory system in which the airways narrow, often in response to a "trigger" such as exposure to an allergen, cold air, exercise, or emotional stress. This narrowing causes symptoms such as wheezing, shortness of breath, chest tightness, and coughing, which are the hallmarks of asthma. Between episodes, most patients feel fine.\n\nfor more information: \nhttp://en.wikipedia.org/wiki/Asthma

The Lungs are made up of millions of tiny air sacs called alveoli. These alveoli are like the millions of little holes in a sponge.\n\nJust out of curiosity, did you feel them in a dissection or something?

I'm not sure of the question because of the way you wrote it but I think you want to know how there body looks inside and out well lung cancer is caused by cancer cells basically dead cells that multiply the looks on the out side of the body is usually a more pale color due to the lack of oxygen in the blood system also on the inside of the body the patient most likely has enfezima which usually means there lungs fill up with flehm and there are no more hairs on there Bronci's to cough it up with and so they usually drown on there own flehm. I've seen hospitals pump up to a quart of flehm from a persons lungs a day so you see it can become pretty serious.\n    The lungs are devided into 3 sections The Bronci the Bronciol and the aviola ducts which are the small sack like objects at the deepest part of the lung they brake down the oxygen and allow it to oxygenate the blood in your system. lung cancer kills those aviola ducts so that they no longer are able to bring oxygen into the blood system without the aviola ducts you die.

i hate to be the one to scare the hell out of you. but i had the same thing burning in my right lung, 8-9-2001 they took my right lung out . i had lung cancer. take my advice see a pulmonologists. my dr kept me on damn cough syrup for a year. and when i started to spitting up blood she says well donald i guess we need to get some chest xrays. then it was too late. see a pulmonologist man. do not go thru what i have been. see my 360 you will know what i mean. also good luck to you.

Asthma is a chronic obstructive pulmonary disease. There are many different kinds of asthma. Extrinsic asthma(asthma that can be clearly associated with exposure to a specific antigen like pollen, grass, dust, etc.),Intrinsic asthma(which cannot be directly linked to a specific antigen), Exercise induced asthma(typically occurs 10-15 minutes after vigorous exercise).During an asthma attack the smooth muscles surrounding the small airways constrict(bronchospasm)causing difficulty in moving air in and out of the lungs.

Unfortunately it can spread to all parts of your body. Most lung cancers are slow-growing, about 80%. The other 20% have most likely progressed to other parts of the body prior to diagnosis.

If you think the brain and the heart work together then all organs work together with the Brain.  Asthma is a respiratory disease where the bronchioles shrink and close off restricting the amount of air getting into the air sacs.  If you have a serious attack you will lose consciousness because of the lack of oxygen to your brain, but most medication can prevent this from happening.

The tumors of lung cancer can grow and replace normal lung tissue which can greatly affect a person's ability to breathe normally.  They may tire more quickly, lowering the exercise tolerance.  \n\nIf there is tumor in the lung, it is often a sign that there is tumor elsewhere in the body, since the lungs are at the front and center of the circulatory system, which can spread cancer cells.  Disseminated cancer can cause a person to lose weight feel perpetually weak, in addition to the specific damage it may do to individual organs.

It is possible to beat lung Cancer but it depends on:\n1. type of lung cancer - Small cell, Large cell, Adenocarcinoma, Mixed type (smallcell type is the most fatal and aggressive while adeno Ca has the best prognosis)\n2. Cancer stage\n3. Age\n4. Co Morbid diseases (eg. heart disease)\n\nBut it is wiser to consult your doctor for prognostication and early treatment

It depends on the person and there is no ratio for this. My dad smoked all his life and died at the age of 84 but not from lung cancer. My mom died of lung cancer when she was 65 and she smoked all her life as well. You'll never know. However, smoking causes other types of cancer such as pancreatic cancer, kidney cancer, cancer of the throat, the mouth and esophagus. Smoking causes Chronic Obstructive Pulmonary Decease including emphysema, which is not reversible. Smoking causes strokes as well. See it is not all about the lungs it is much more involved. Set a quitting date and do it, it is never to late.

You have small, fine hairs in your nose and lungs as a filtration system to keep anything unhealthy from getting in. Unfortunately, the hairs, to do their job, are very moist and sticky, like fly paper. Eventually, there is a build up of waste, and you sneeze (nose) or cough (lungs) to clear it out. Then you grow new hairs and start again.\nThis is why smokers are constantly coughing. And why they get lung cancer when they've overloaded their lungs filtering system.

hmmm..\nyou can see how albuterol sulfate (asthma medicine) changes someone's breathing or heart rate lol
