Lungs

To assist in removing dust particles and other unwanted foreign bodies that have entered the air passages.

The bronchioles are divided into three types, each becoming progressively smaller. Terminal bronchioles are the second type and the final airways in the conduction zone. All bronchioles control the amount of air distributed through the lung by constricting and dilating.

Lungs are located in the pleural cavities which are part of the thoracic cavity.

No.

a medical device which is designed to help patients breathe when they have difficulty doing so on their own.

Gullet

the state in which a reduced amount of air enters the olveoli in the lungs

paralle, sheetlike layers of thin tissue that contains blood vessels

No its actually the same size. It's been proven by docters.

My Iron Lung was created in 1993.

PTB means pulmonary tuberculosis. It heals with residual fibrosis.

A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.

Small amount of fluid in the lungs may not cause any pain. It can occur with viral infection, anaemia, heart failure. It may cause shortness of breath if more fluid accumulates and causes the lung to collapse. Certainly you will need further investigation.

When you breathe in, your diaphragm will contract, causing your lungs to expand and suck in air. When you breathe out, your diaphragm will relax, causing your lungs to shrink and force out air.

The air in your lungs expands in volume as you get closer to the surface of any water you swim in. This is because the air was compressed when deeper due to the pressure of the water around you. This is why when scuba divers always exhale while ascending to avoid rupturing their lungs as the air expands.

Oxygen and carbon dioxide are exchanged in the lungs by different means. Carbon dioxide is dissolved in the blood stream as carbonic acid (CO2 + H2O --> H2CO3) and is important in maintaining our pH, or acid-base balance, at 7.4. Excess carbonic acid is turned back to carbon dioxide in the lungs due to diffussion and exhaled.

Oxygen is actively absorbed by the hemoglobin of the red blood cells, attaching to an iron ion at the heart of the hemoglobin protein. Oxygen does not significantly dissolve in the blood stream.

alveoli is the site for gaseous exchange. They are the air filled sacs where carbon dioxide and oxygen is exchanged

MI causes heart failure. . in heart failure , the increase of left ventricular pressure with failure of blood to pump into aorta occurs. . leads to back flow of blood into lungs through pulmonary veins. . this results to interstitial pulmonary odema and opening of alveoli , during inspiration is not normal, with external pressure to its normal opening. . this takes place with a sound , called fine crepitations

It could be due to some really serious diseases or disorders, so you should go to the doctor to find out what is causing yours. Old blood turns from red to black-looking, so if you have had a really bad infection like bronchitis, it could be that you have had some minor bleeding from the infection in your lungs or bronchitis. Blood from your nose and sinuses can also mix with your nasal mucus, run down the back of your throat with post nasal drip and look black when you cough it up. There are many much more serious problems that can cause it, so it should not be ignored as a warning sign, have the doctor examine you.

Black-looking phlegm you cough up can be residue from smoking that is stuck in your respiratory tract. It includes the tar from the burning process and can be caused by both marijuana and cigarettes. Smoking both is the ultimate bad choice. I've been coughing up black phlegm for about a month or two now and am quitting cigarettes and marijuana for good.

Face it, burning and inhaling smoke from anything can't be good for you, so get the will power to stop. The doctor can help you find help to stop. The longer you wait, the worse it will get. Waiting until later will cause you to become more addicted and have much more difficulty stopping.

Smoking isn't cool anymore...

It is either old blood, dead tissue, a substance from out of your body or a black mold infection.

Black mold infection is a dangerous disease that should be treated immediately.

If you want to inhale substances without getting tar and other filth in your lungs, use a vaporizer or e-sigarette instead.

Most thyroid conditions are not life threatening. However, thyroid function is closely linked to heart function, and an excess of hormones suddenly released by the thyroid, or taken as thyroid supplements, can kill you.

Spelunkers lung, is a lung disease caused by cave exploration where bat excrement is present. The excrement may contain a fungus. This fungus' spores are inhaled into the lungs causeing inflammation. Also see: Acute Symptomatic Pulmonary Histoplasmosis.

It's associated more with caves in tropical / sub-tropical regions, and holding very large bat colonies.

I have never seen the name "spelunkers' lung" in any serious report - it's always called simply 'Histoplasmosis'. "Spelunker" is an old-fashioned term concocted by two American cavers in the 1930s(?), and after a decade or so of normal use, though only in the US, it became a term of derision among American cavers themselves, and is now rarely if ever used in caving literature.

both... reason you have ribs which if you feel are on both side...
