Lungs
Lungs are a pair of elastic and spongy organs that help the body breathe. They are present inside the rib cage in thoracic cavity of humans.

What is the Diagnostic procedure used to assess the volume and airflow rate of the lungs?
A spirometer is used for measuring the amount of air breathed in and out but a more precise measurement of lung volumes may be obtained using plethsmography which involves sitting in an airtight box and breathing gases via a tube.
During a plethsmography you can spend up to an hour in that airtight box ...
The lungs are two air sacks located in the chest. They are a storage place for air.
A lung is an organ in many species that allows the animal to breath and transfer oxygen into their blood.
Saclike respiratory organs in the thorax of humans and the higher vertebrates.
How many lungs do wolves have?
A dog has six lung lobes. The right lung has cranial, middle, caudal and accessory lobes, and the left lung has a cranial and caudal lobe.
Note. The cranial portion of the left lobe also has a cranial and caudal part, so it looks like the left side has three lobes.
Black lung disease is associated with this industry?
Mining
- "Black lung" is also known as "coal miners' pneumoconiosis". As the name suggests - this condition is most commonly associated with coal miners who breath a large amount of coal dust over a number of years into their lungs. But it is not just coal miners who suffer this condition as it is the inhalation of carbon fibres which can cause it - so any workers associated with carbon, such as grinders can suffer the condition. To read more about black lung and how to claim compensation in the UK if you have suffered from black lung see the associated link entitled "black lung disease claims".

What is the blood leaving the lungs called?
MEEP MEEP! why do u care about this question? having lung problems? meepo!!

What two factors prevent the lungs from collapsing?
surfactant- the substance that your lungs produces. Also continuous pressure from the air in there.
What is a disease caused by inflammation of the mucus membranes inside the bronchi tubes?
The term bronchitis is used for a non-specific inflammation of the bronchi, the branches of the trachea that extend into the lungs.
Is there an autoimmune cancer?
No. In an autoimmune disease, the body attacks his own cells which become for unkonwn reason recognized as a foreign body (antigen). While in cancer, certain body cells divide without control. So autoimmune and cancer indicate unrelated terms.
What is the main function of the bronchioles?
There are two primary bronchi which are the first divisions branching off from the trachea to take air into the lungs. The primary bronchi then subdivide into lobar bronchi and then again into tertiary bronchi which continue to divide until they are tiny bronchioles which supply each of the alveoli in the lungs.
The left primary bronchus leads to the left lung and the right primary bronchus leads into the right lung. The bronchi contain rings of hyaline cartilage which help to provide flexible support to the airways.
What happens if no air goes to your lungs?
If you do not get enough Oxygen in your blood you can die.
What does secondary bronchi mean?
There are five (5) secondary bronchi (aka lobar bronchi).
Three (3) on the right:
1) superior lobar bronchi
2) middle lobar bronchi
3) inferior lobar bronchi
And two (2) on the left:
4) superior lobar bronchi
5) inferior lobar bronchi
How does the structure of the primary bronchi compare with that of the trachea?
Trachea contain cartilage rings, and is the long tube that goes to the lungs. The bronchi contain cartilage plates and are the branching tubes that go to the lungs.
Oxygen is transfered into the blood at alveoli. Oxygen travels along the pulmonary vein into the left ventricle of the heart. It then travels along the aorta to the body tissues, gathering impure blood (CO2) along the way. Travels back to the heart via the Vena Cava and all impure blood is emptied into the right atrium of the heart, before it travels back to the lungs via the pulmonary artery.
Do sea turtles have lungs and gills?
This is actually a hard question to answer.
Because Turtles can actually diffuse oxygen from the water with what is commonly referred to as Bum Gills. They aren't actually gills, but have the similar function.
How does smoking affect gas exchange in the lungs?
well, the effect is very basically, scaring of the lungs due to the amount of coughing. in the gas exchange, normally less oxygen is absorbed because of the carbon dioxide from smoking, which normally is the cause of chronic bronchitis. emphysema is just where a person gets loads and loads of infections which makes the person ill, cough alot, get scares on the lungs which weaken them meaning alveoli might not absorb as much oxygen into the blood stream or as much carbon dioxide out of the blood. THIS IS A VERY BASIC TASTE OF THIS, for more, just type this into google "define: (the name of the disease goes here)"
Are human lungs hollow inside?
Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. This exchange of gases is accomplished in the mosaic of specialized cells that form millions of tiny, exceptionally thin-walled air sacs called alvioli
Which of the main bronchi is more horizontal?
The right main bronchus is wider, shorter, and more vertical than the left main bronchus, and it enters the right lung at roughly the level of the fifth thoracic vertebra.
In contrast, the left main bronchus is smaller in size, but longer in length than the right main bronchus. The left main bronchus enters the root of the left lung opposite to the sixth thoracic vertebra, passes underneath the aortic arch.
What is the medical term meaning dilation of a bronchiole?
Bronchiectasis is the medical term for dilation of the bronchi. It is a chronic necrotizing infection of bronchi & bronchioles causing abnormal permanent dilation of these airways.
Rationale: Dilation (-ectasis) of the bronchi (bronchi/o = bronchus).

The correct way the measure vital capacity is by using a spirometer.
It can also be estimated this way:
Vital Capacity can be measured with a string, calculator, ruler and balloon, believe it or not. Blow up the balloon and let it out a few times to stretch the rubber. Then take a very deep breath and blow out all the air that you can into the balloon. Tie it off. Pass the piece of string around the widest part of it to measure it. Using the ruler, measure the string. (My VC is very good, it's 4.2, and so my string was about 60cm long.) Divide the meaurement of the string by pi (if you don't have suitable calculator, you can divide by 3.14 on a standard calculator) and compare the number to this chart: Balloon diameter (centimetres:)
is your final number that you got by dividing by pi. Balloon diameter: Approximate vital capacity in litres:
8 0.3
9 0.4
10 0.5
11 0.7
12 0.9
13 1.2
14 1.4
15 1.8
16 2.1
17 2.6
18 3.0
19 3.6
20 4.2

Theoretical vital capacity:
Look for Vital capacity in Wikipedia for the formula. There are also online calculators.
What happens to your lungs when you smoke a cigarettes?
The lungs become coated by deposits of tar, which makes them turn black.
The alveoli (air sacs) get pushed out of shape by the tar. The alveoli are where gas exchange took place, so this is made less efficient because hey are a different shape.
You are more at risk of lung infections, becasue the nicotine in cagarette smoke aneasthetises the cilia (little hairs) that line your throat and windpipe, so they cannot trap dirt and germs. This means that the germs can go down into your lungs when you breathe in, and this will make you ill.
You are more likely to develop lung cancer because tar is a carcinogen (cancer causing substance)
Describe the gas exchange in the lungs?
Gases as a law exist independently of each other
Gases move rapidly and randomly
So in the alveoli (lungs air bags) we have "fresh" air entering this has Approx 80% Nitrogen 19%oxygen and a little carbon-di-oxide and other gases.
In our blood we have high carbon-di-oxide levels in the air we have low carbon-di-oxide levels and vice versa for oxygen
If you have smelled perfume and noticed that you can smell it from far away that's a result of diffusion.
Effectively the respiratory gases diffuse to equalize in concentration in both the blood and in alveoli. Basically in blood (deoxygenated) CO2 concentration is 50 mmHg in the air sacs it is 45 mmHg so they try t equalize.
This results in carbon-di-oxide leaving the blood and entering the alveoli.
The same thing happens to the oxygen. It's higher in air than in blood so the oxygen moves from high concentration (in air) to low concentration (in blood)
The end result is carbbon-di-oxide leaving blood and oxygen entering blood this is a basic!!! overview of the gas exchange.
