Lungs

Both. We have two lungs, one in each side of the chest.

Emphysema cannot be reversed.

size of an openig is a compromis betwin a need to have enough air and risck of drying respiratory membrane(it can only conduct air and CO2 when moist)

I would say it is something she should talk to her doctor about right away. They will tell her if she should be concerned or not. I would say that if it is not troubling her she should not worry about it, dont waste time going to the doctor and spend more time with the family

emphysema

Lungs consist of a series of tubes of ever-decreasing size, which carry air to and from the blood at the gas exchange surface in the 'alveoli'. These alveoli are microscopic hollow balls (at the ends of thousands of tubes) which are covered on the outside by blood capillaries (extremely narrow blood vessels) and a thin layer of mucus on the inside, which increases the speed at which the air diffuses into and out of the blood. The spherical shape of the alveoli, the microscopic width of these hollow balls (allowing more to fit within a small space) and the density of blood vessels inside the lungs all maximise the surface area. A last, important note: the lungs are NOT 'designed'; human lungs have evolved from simple gas exchange organs like the lungs of lungfish, becoming increasingly complex over a very long period of time.

Most human beings are born with 1 pair of lungs, a left lung and a right lung. The left lung holds both the cranial and caudal lobes . The right lungs holds the middle, cranial and caudal lobes.

It appears to be a report of an X'ray or CT scan of the chest. It means that there is an inflammatory patch in the lung possibly infection which needs to be correlated with the symptoms, treatment and a repeat investigation to make sure it has cleared with treatment

Lungs and respiratory system

The Respiratory Membrane

Every organ is connected to the lungs by blood vessels. The heart is directly connected.

Bc u r sick, maybe having a fever

I have this also. It's now been eight years since I first knew I had breathing difficulty. I had incorrect diagnoses, and several second opinions. Recently found I have Constrictive Broncheolitis, breathing capacity of only 32%, and I need a lung transplant. I started with my local pulmonologist who said adult onset asthma and emphysema, then Mount Sinai in NYC who said Sarcoidosis, Yale said Broncheolitis, so did the Mayo Clinic who pointed out my heart valve severity (I elected Sinai treatment), NY Columbia Presbyterian, the Cleveland Clinic where I will be treated for my heart valve and lungs. The best hospital for lungs is National Jewish in Denver. However the Mayo and Cleveland clinics are excellent. I strongly urge you go to one of them. They won't be not quite sure, they will find out! Don't waste any time. Most insurances cover second opinions, and so does Medicare. If yours doesn't, do it any way - what good is money if you're dead? Good luck to you!

The alveoli

It means that 65% of a persons lungs are working, while 35% is not working, likely due to smoking. Emphysema is a good example of a disease that reduces lung capacity.

Lung over-expansion injuries are most commonly found in scuba diving accidents and normally occur as a result of holding your breath while ascending. The gas inside the lungs expands as the diver ascends and if the pressure is not released through exhaling then the lung can rupture. Depending on where the rupture occurs depends on the severity of the injury and it's classification. There are 4 main types (classifications) of lung over-expansion injuries...

- air embolism - Air entering the blood stream through the alveoli.

- mediastinal emphysema - Air escaping into the chest cavity and putting pressure on the heart as well as other organs.

- subcutaneous emphysema - Air trapped under the skin, normally collecting around the neck or collar bones.

- pneumothorax - Air entering the lung sack and collapsing a lung.

Symptoms may improve when the patient is treated with emergency oxygen on the dive boat but any lung over-expansion injury should be considered life threatening and will need to be treated in hospital.

Yes

Carbon dioxide

The tiny sacs insure that the maximum area of tissue can be in close contact with the blood vessels to facilitate gas transfer

Pathological lung sections differ from normal lung tissue. Pathological lung sections include the pathological tissues of fibronectin, collagens, and proteoglycans.

If both lungs were removed, the person would die.

It's called the pleural cavity. See the related link for more information.

after a long period of time smoking, a smokers lung becomes black do to the tar inside of their tobacco product. tar is like a thick, gross, stick black fluid that builds up in your lungs (only if u smoke or receive second hand smoke). it can never come out of your lungs, it just kinda settles there. :) hope i helped
