Lungs

Lungs excrete carbon dioxide and kidneys excrete urea and other substance

Gills are more efficient at obtaining oxygen, but there is much more oxygen in air to breath through the lungs.

IDK but I think that u die

While the bronchoscope is moving down the throat, additional anesthetic is put into the bronchoscope to anesthetize the lower airways. The physician observes the trachea, bronchi,

right ventricle

Yes. People get lobe transplants all the time. There are two lobes on the left side of your lungs and 3 on the right. For a lobe transplant, two donors each give one lobe to the recipient and a fragment of one side of their lungs. (One person left, the other right) After, the person usually recovers fully after 4-10 days. It can be dangerous to the donors health, though if they develop a lung disease later in life. It was first tested on animals, before people started using it in the early 1990's.

Whenever you inhale and exhale, Oxygen gets supplied into and out of your lungs to power you everyday and keep you going. We get Oxygen which gets supplied into your blood which is essential to keep you alive. Lungs are part pulmonary system, which is the essential respiration organ.

There are two main gasses that are exchanged in the lungs: carbon dioxide and oxygen. The lungs use tiny air chambers called alveoli to take in oxygen and let out carbon dioxide.

There is a test called the "Methacholine Challenge." This tests your lung capacity, and is used by MEPS (military entrance processing station) to determine if someone has the lung capacity to participate in the US military.

I myself took this test shortly after turning 18, only to determine my lung capacity was not high enough, thanks to my own carelessness (smoking heavily for the days leading up to my test). In brief, they hook you up to sensors, put a mouthpiece-like object in your mouth, and you inhale and exhale as much oxygen as possible for a 5 minute period. During this test, they administer Methacholine into your lungs to determine the volume of your lungs, and if you have any symptoms of ashtma etc.

Hyperinflation of the lungs is a term used to describe excessive, large or heightened increase in lung tissues. Hyper in the medical field means excessive.

No. Total myth. Doesn't make any medical sense at all. Smoking tobacco is bad for you, but smoking marijuana before it won't make it worse.

In Europe and Australia, people often smoke tobacco with weed. I personally enjoy a cigarette after a bong while I'm coming up.

none of them because they have cigarette budds in tem

The membrane lining on the lung is the visceral pleura and the membrane lining the inside of the chest cavity is the parietal pleura.

Yes. Like all mammals, platypuses breathe using lungs. When they are hunting for food in creeks and rivers, they need to surface frequently to breathe.

First, the body makes you cough, trying to dislodge the item. Coughing will continue, but the body also begins to "fight" the item as an invader. It tries to wall it off. This activity triggers mucous to collect aaround the item, which can increase coughing. If coughing dislodges the item, the body's defenses stand down, but macrophages still do clean up afterward.

The body has a double circulation the blood passes through the heart twice in one complete circuit.

To the extent that silicosis can lead to tumor production, and the formation of tumors is thought to be a stepping-stone for carcinogenesis, yes, the occurrence of silicosis can herald in cell dedifferentiation, and thus cancer.

According to wikipedia's article on the composite of gasses which we breathe every day (Air): It contains roughly (by molar content/volume) 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, trace amounts of other gases, and a variable amount (average around 1%) of water vapor.

Trachea, primary bronchi, secondary bronchi, tertiary bronchi, bronchioles, and alveoli!

The short answer is yes. The long answer depends somewhat on what you mean by "twice". Cancers can relapse, meaning the original disease returns. This usually happens because microscopic "islands" of cells from the original neoplasm (tumor) were missed during removal procedures. Sometimes this is due to error, but usually it is due to the bloodstream carrying neoplastic cells to other parts of the body. If these cells stop in a cytologically compatible place (a place with similar cells in a biological sense) they can grow there. This is called metastasis and has a poor prognosis. The most compatible place for neoplastic cells to grow is elsewhere in the lung, or in the other lung.

One can also develop an unrelated lung cancer - either the same kind or a different kind. This is a very rare occurrence, made more probable by those exposed to risk factors for cancer, such as exposure to smoke (from smoking or other sources) or fine particulates of certain sorts (asbestos, for example).

You should really go to the doctor it could be neumona I would go get that checked out

These volumes are needed when there is suspicion of restrictive pattern, which can be presented along with obstructive pattern with FVC < 80%.

The gullet, also known as the esophagus, leads to the stomach, not the lungs. The windpipe, also known as the trachea, does connect to the lungs.

High altitude affects respiration because there is less oxygen in the air. Because of this, more and stronger breathing is needed to supply oxygen to the bloodstream.

The mucus that forms from cystic fibrosis affects the gas exchange in humans. The build up from cystic fibrosis can affect the gas exchange by increasing carbon dioxide and decreasing oxygen.
