Lungs

The only animal that has true lungs and gills is the lungfish. Animals like frogs often have gills for a portion of their lives and then later develop lungs.

severe lung disease which limits activities of daily living. There should be potential for rehabilitated breathing function. Attempts at other medical treatments should be exhausted before transplantion is considered.

The two tubes leading into the lungs are the bronchi. They are branches off the trachea, and bring air into and out of the lungs.

Pleura covers the lungs. It has 2 folds- the visceral (inner) pleura and the parietal (outer) pleura.

This is a pneumothorax or collapsed lung. It is generally brought on by a puncture in the chest that allows air into the chest cavity outside the lung. As the diaphragm expands, air is drawn in through the hole in the chest wall, and the lung will not fully expand. After a short period and continued respiration, the lung will not be able to inflate. Gas exchange will then be seriously reduced or not occur at all, and the victim willl rapidly begin to suffocate. Use the link below for more information.

The diaphragm moves down when you breathe in, so your lungs will expand to take in as much oxygen as possible.

Pharynx, trachea, bronchi, alveoli

To keep you alive by breathing for you. It is in the lungs that venous blood containing Carbon Dioxide comes to so you can breathe it out (exhale) and then picks up Oxygen (inhale) to distribute it throughout the body via the arteries.

Semilunar valves are found throughout the body in veins, as they prevent backflow of deoxygenated blood. In the heart, there are two semilunar valves, the pulmonary semilunar valve and the aortic semilunar valve. The pulmonary semilunar valve is the gateway to the pulmonary artery, which then goes to the lungs. The aortic semilunar valve is the gateway to the aorta, which distributes oxygenated blood to the rest of the body.

Horizontal fissure of the right lung and Oblique fissure of right lung.

The left lung only has 2 lobes (superior and inferior) because the heart takes up much of the space allowed on the left side. The right lung; however, has 3 lobes (Superior, Middle, and Inferior).

Yes. The left lung is a little less voluminous than the right lung. It has two lobes, whereas the right lung has three. Its volume is displaced a bit more, by the location of the heart, than the right lung.

The main five parts of the lung are included in the next sentence. The parts are the bronchial tree, larynyx, aveoli, trachea, diaphragm. The lungs are the organs responsible for breathing, the alternate inhalation and exhalation of air.

Lung scarring is a serious medical condition that require immediate attention and treatment. It can be treated by medication and evaluation by medical doctors.

It is called pneumothorax. "Pneumo" is the medical root word for "air" or "lung(s)". "Thorax is the medical root word for "chest" or "chest cavity". Never be intimidated by "medicalese" or "medical technobabble". All those intimidating sounding words are made of simple building blocks, namely medical root words. You can always look them up on Wikipedia or at The National Institute of Health's website: nih.gov/ (-:

Yes of course

visceral pleura

I am not a doctor so I can't give medical advice.

The cancer can change the tissue. It can impair the airways by decreases the size of the airways or it could interfere with gas exchange through the air sacs in the lung. A person breaths by inspiring oxygen and exhaling CO2. Anything that interferes with that gas exchange makes it more difficult to breath. The degree of interference and the placement of the interference affects how difficult it is to breath. The problem starts when get a tumor. A biopsy is advised to determine what type of cancer it is and if it benign or malignant. If malignant the concern comes about isolating it and removing it if possibly. People can have the tumor to a lobe to a section of the right or left lung when if in this case should be removed. Many cancers are progressive and increase in size with time and that further interferes with the ability to breath. Having worked with lung cancer patients and seeing them die is a dreadful and sad experience. Imagine a world of difficulty breathing which is always ever present.

A good way to know how it feels to be short of breath is to remember the times after you have just run a distance and you feel out of breath. Imagine having that feeling all of the time probably to a lesser degree though. Diagnosing the Cancer early helps in preventing the spread and gives the person a better chance of surviving.

If I found out or suspected I had cancer I would see a doctor ASAP which would give me a better chance of surviving the disease and having a more normal life but this depends when the disease is caught, the type of the cancer, and whether is was spread from somewhere else. Remember I am not a doctor so I can't give medical advice.

No because the lungs are slightly different in size. The left lung is smaller and has two lobes. The right lung is larger and has three lobes. This difference is mainly due to the heart occupying more space on left side of the thoracic cavity.

The epiglottis.

Opacity in the right upper lobe means that there is either a mass, or fluid present in the lung. Suspicious likely means that the doctor is thinking it could be something harmful.

A lot. Dogs, Cats. Almost all animals have lungs.

Both lungs are different sizes
