Lungs

1.They are single cell thick

2.Thin film of moisture covering the alveoli allows the oxygen to dissolve in therefore making the process efficient

3. they have a large surface area

4.they are surrounded by network of blood capillaries maintaining the concentration gradient for the gaseous exchange

there are two primary bronchi which branch off into secondary bronchi which supply air to the lobes of the lungs

Apex

The right lung has 3 sections and the and the left has 2. That makes for One secondary Bronchi per section.

The pleura. I suggest you do a web search on this for a diagram, and so you understand the different layers and where else the pleura can be found.

There are two ways to expand your lungs:

1. Muscles in your chest expand your Rib Cage and pull your lungs outward, expanding their volume.

2. Your Diaphram muscles pull downward and expand your lungs downward.

Lung size is proportional to body size. Respiratory tests for diseases like asthma use this fact to determine what your lung capacity "should" be to determine how impaired it is by measuring exhaled breath volumes. Generally the volume is proportional to the cube of the height of the patient compared to observed lung volumes in autopsies. This comparison is age dependent as you get to be about 20, you stopped growing lung tissue and your lung capacity stabilized. This lasts for about 10 years. At about 30 your lungs are on a decline. and you lose 20 percent of your vital lung capacity by about age 35. By 50, you've lost 40 percent of your breathing capacity and the decline continues for life.

This depends on whether you are referring to preventing it happening in the first place, or stopping it once you have it - tho' the two answers overlap, tho' no-one can yet be certain, as the cause-and-effect of cancer is not known, just parts of this chain of events. The central factor is that a cell's DNA is changed such that the cell avoids death and proliferates increasing amounts of 'daughter' cells. Some things that cause this are radiation (including background radiation), substances that enter the cell and disrupt the normal cell processes and thus prevent the usual repair mechanisms, etc. Then there are things that prevent the immune system from recognising that a cell has gone rogue and thus getting rid of it before it proliferates.

Prevention: as cancers were rare in past times, it is now certain that there is something in modern Western lifestyles that has caused the explosion of cancer. The weight of evidence is that exercise, good nutrition (fresh fruit, veggies, low carbs, omega3 oils), avoiding carcinogens like smoking and asbestos, polluted water (arsenic) and environment (painters are at risk; enhanced background radiation from granite).

'Cure': presently thought impossible, only able to drive cancer into remission - where it may be dormant, but likely to return. There are 'standard' treatments - chemotherapy, surgery (cut out the cancerous parts and nearby tissue), radiation, and immunotherapy (BCG for bladder cancer, Provenge for prostate cancer). Each of these has its own dangers - chemo is inherently poisonous, but hopefully more to the cancer cells than the normal ones; surgery may spread the cancerous cells around the body; radiation will burn surrounding normal cells/organs - and thus shorten life on their own. So it is a balance of risk.

There are supplements that help make the standard treatments work better - enhance their efficacy and lower the side-effects, thus extending survival (vit.D3, Omega3, low-carb/avoid sugar and alcohol, etc).

The Internet is awash with promises of cures. It is possible, tho' unlikely, that one or more may help. Some have more science behind them than most.

There is a problem that orthodox doctors are admittedly ignorant of the supportive enhancers (diet, supplements, exercise) and so are unlikely to adequately advise on them. There is little genuine double-blind trials of standard treatments (this is not to decry them), just lengthy experience - but which means it can often be decades before it is known whether a new treatment is better than earlier ones.

Bronchi divide into bronchioles.

I don't understand what your implying in the question, but oxygen-rich blood returns to the heart through pulmonary veins; these enter the left atrium. I hope that was helpful.

Aleoli

Could possibly have an infection. are there other problems? Does it burn when you urinate? Feel like pressure in the lower abd area? Any discharge from the penis? Hurt to have sex? if you answer yes, to any of these questions could be an infection but the best thing to do is to let someone check you over. Don't know where you live but the local health dept can check for infection.

I would ask your local tattoo artist. If your taking Chemotherapy your immune system is usually weakened and infection is more likely. But if you talk to the artist who will be doing your tattoo, he may do it but with more strict aftercare instructions.

We breath because the oxygen/CO2 levels in our lungs are less than that of our surroundings. When you breathe in, your lungs expand and allow more oxygen to flow in. When you exhale, the CO2 levels in your lungs is greater than the your surroundings, so the CO2 leaves and the process repeats itself. This is called negative pressure breathing.

If you have lungs of gills please contact your doctor for everyones sake.

No you cannot live without your lungs. Some people are currently living on one lung but you must have at least one lung. The lung is responsible for collecting and distributing the oxygen you need in order to breathe.

Cancer is a disease that makes body cells turn wicky-wacko and replace all the good cells, and that eventually turns your body parts wicky-wacko. and you can die from it becuz its really bad 4 u. you can eat a cancer by chewing on it, then you get canser :D:D:D:D:D:D:D:D:D:D:D:D:D yes u can get cancer cuz judith said so! :D my mom said im special!

Blood is the conduit for oxygen around the human body. If the blood did not circulate through the lungs, oxygen could not be carried around the body. Added to that, decreasing the amount of carbon dioxide is also an essential function of the lungs; the deoxygenised blood needs to relieve itself of the carbon dioxide and collect the oxygen again. The carbon dioxide is then breathed out via the lungs.

The diaphragm below the lungs, which one of the body's strongest muscles, lowers and raises again, drawing air into the lungs and pushing it back out again. "Hiccups" (hiccoughs) are caused when a stimulus of the vagus nerve triggers a sudden lowering of the diaphragm, drawing air in and forcing the vocal cords closed in the larynx.

Right bronchus

To make room for millions, if not billions, of alveoli, small air sacs used to capture air to be dissolved into your blood.

Bird's have lungs, and no gills, because they are birds, which have lungs, and are not very aquatic. Some birds go underwater, like pelicans and penguins, but they have to surface from time to time. They can hold their breath for a long time, but they still have to breath occasionly.

The parietal pleura.
Pleura is the outer covering of Lungs
The pleurae are the membranes covering the lungs.
The membrane is called the pleura, which is named the parietal pleura for the portion of the membrane covering the inner chest wall and the visceral pleura for the portion of the membrane covering the lung. The potential space between the visceral and parietal pleurae is called the pleural cavity.
its called pleural membrane surrounding the lungs n also contain pleural fluid reduces friction during breathing
